Revealed here in it's entirety is a patent which, due to probable
suppression by political, military and/or economic interests, you've never
heard about. Granted to inventor Howard Johnson on April 24, 1979, the
rights to which have expired since 1996, patent number 4,151,431. See there
also patent number 5,402,021, also issued to Howard Johnson March 28, 1995
which continues to build upon the very same principals. These may, in fact,
prove to be some of the most important documents in the history of mankind.
Click the image to the left for a detail view.
In short, it is a patent for a device capable of producing unlimited free
energy with zero environmental impact. A device resembling an electric motor
which produces work without electrical input, using only permanent magnets
for motive force. What some might call perpetual motion. What the inventor
believes is the harnessing of energy not thought possible by conventional
science based on "incomplete information and theory with respect to the
atomic motion occurring within a permanent magnet." He then goes into a
lengthy discussion of his theories, which may or may not be accurate, and I
am not qualified to say one way or the other. The fact remains, however,
that he DOES have a working model of the invention. What ever path he took,
he arrived at the same place.
Featured in the now defunct publication Science and Mechanics magazine,
Spring 1980 edition, it took five and a half years from the date of the
original filing and many legal battles with the patent office to get it
approved as they have a "policy" (due to so many fraudulent submissions) of
not patenting any device which in any way resembles perpetual motion or over
unity. Our assurance that this is no hoax.
It is my firm belief that this patent was suppressed due to the
inevitability that devices built and sold based on the principles described
therein would force the total economic ruin of petroleum producing nations,
the complete decentralization of power generation and totally eliminate the
need for the consumption of fossil and nuclear fuels of any kind, for the
production of energy of any kind, be it electrical, heat or motive force.
Period.
Granted, it will likely result in global economic chaos and political shifts
in power. It will, without a doubt, completely wipe out many industries.
Especially the petroleum industry which will all but disappear forever.
Never completely, though. We'll always have a need for plastics, lubricants
and other petroleum products. But given the benefits of zero or even
positive environmental impact and the virtually eliminated financial burden
on businesses and families for energy, who can deny that the benefits
outweigh the negatives?
Just imagine never wanting for energy again. Imagine no coal fired power
plants belching out black soot and pollutants to satisfy our gluttonous
energy needs, but rather, electric generators in every basement. Imagine
cars with NO exhaust and no engine noise that can't run out of gas and
deliver more horsepower than most sports cars of today. Imagine no gas
stations contaminating our ground water, no oil barges or derricks spilling
crude. Imagine no power lines, no pipe lines, no wind turbines, no solar
panel arrays, no hydroelectric dams cluttering up our landscapes. Imagine
taking a breath of fresh air again or basking in the sun without fear of
cancer. Imagine restoring and preserving this tiny spaceship earth for our
children. We are empowered, and thus obligated to do so.
Having said that, here now, in it's entirety is the patent. If you can
duplicate this device and create working units for yourselves and/or for
open sale to the public, may God bless you. Incidentally, according to the
S&M article, the ferrite graph on the first page belongs to another patent
but the patent office was so shaken by the whole ordeal that, for what ever
reason, they insisted it be put there anyway. In the interest of preserving
the integrity of the original, it has not been excluded here. Read and be
enlightened.

Magnetic rotation apparatus
Abstract
The magnetic rotation apparatus of the present invention has first and
second rotors rotatably supported and juxtaposed. The first and second
rotors are connected so as to be rotatable in opposite directions in a
cooperating manner. A number of permanent magnets are arranged on a
circumferential portion of the first rotor at regular intervals, and just as
many permanent magnets are arranged on a circumferential portion of the
second rotor at regular intervals. Each permanent magnet has one magnetic
polarity located radially outward from the rotors, and has the other
magnetic polarity located radially inward toward the rotors. The polarity of
each permanent magnet, which is located radially outward from the rotors, is
identical. When the first and second rotors are rotated in a cooperating
manner, the phase of rotation of the permanent magnets of one rotor is
slightly advanced from that of the permanent magnets of the other rotor. One
of the permanent magnets of one rotor is replaced with the electromagnet.
The radially outward polarity of the electromagnet can be changed by
reversing the direction in which a current is supplied to the electromagnet.

TECHNICAL FIELD
The present invention relates to a magnetic rotation apparatus in which a
pair of rotors are rotated by utilizing a magnetic force.
BACKGROUND ART
An electromotor is well known as a rotation apparatus utilizing a magnetic
force. For example, an AC electromotor comprises a rotor having a coil, a
stator surrounding the rotor, and a plurality of electromagnets, disposed on
the stator, for generating a rotating magnetic field. An electric power must
be constantly supplied to the electromagnets in order to generate the
rotating magnetic field and keep the rotor rotating, i.e., an external
energy, or electric energy, is indispensable for the rotation of the rotor.
Under the circumstances, a magnetic rotation apparatus, which employs
permanent magnets in lieu of electromagnets and can rotate a rotor only by a
magnetic force of the permanent magnets, is highly desirable.
The present application proposes a magnetic rotation apparatus which
comprises a pair of rotors rotatable in opposite directions in a cooperating
manner, and a plurality of permanent magnets stationarily arranged at
regular intervals on the peripheral portion of each rotor. One end portion
of each permanent magnet of both rotors, which has the same polarity, is
located radially outward of the rotors. When the two rotors are rotated in a
cooperating fashion, a permanent magnet on one rotor and a corresponding
permanent magnet on the other, which form a pair, approach and move away
from each other periodically. In this case, the phase of rotation of the
magnet on one rotor advances a little from that of the corresponding magnet
on the other rotor. When the paired permanent magnets approach each other,
magnetic repulsion causes one rotor to rotate. The rotation of one rotor is
transmitted to the other rotor to rotate the same. In this manner, other
pairs of magnets on both rotors sequentially approach each other, and
magnetic repulsion occurs incessantly. As a result, the rotors continue to
rotate.
In the above apparatus, in order to stop the rotation of the rotors, a brake
device is required. If an ordinary brake device is mounted on the magnetic
rotation apparatus, the entire structure of the apparatus becomes complex,
and a driving source for the brake device must be provided separately.
The present invention has been developed in consideration of the above
circumstances, and its object is to provide a magnetic rotation apparatus
including a brake device for suitably stopping the rotation of rotors.
DISCLOSURE OF THE INVENTION
The magnetic rotation apparatus of the present invention is provided with
magnetic force conversion means which is substituted for at least one pair
of permanent magnets of the paired rotors. In a normal state, the magnetic
force conversion means causes a magnetic repulsion, as in the other pairs of
permanent magnets. When it is intended for the rotors to stop, the magnetic
force conversion means causes a magnetic attraction force. Since a magnetic
attraction force can be produced between the rotors at any time, the
magnetic attraction force serves to stop the rotors. The brake device
constituted by the magnetic force conversion means differs from an ordinary
brake device which forcibly stops a pair or rotors by using a frictional
force. In the brake device of this invention, by converting a magnetic
repulsion force to a magnetic attraction force, the rotors can be braked in
the state that the movement of the rotors is reduced. Thus, the rotors can
be stopped effectively.

FIG. 2 is a schematic plan view showing the relationship between the first
and second rotors;
FIG. 3 is a perspective view of a permanent magnet;
FIG. 4 shows an electromagnet, a permanent magnet cooperating with the

FIG. 5 is a view for explaining how a pair of rotors rotate.
BEST MODE OF CARRYING OUT THE INVENTION
FIG. 1 shows a magnetic rotation apparatus embodying the present invention.
The magnetic rotation apparatus has frame 1. Frame 1 is provided with a pair
of rotation shafts 2 which extend vertically and in parallel to each other.
Shafts 2 are located at a predetermined distance from each other. Upper and
lower ends of each shaft 2 are rotationally supported on frame 1 via bearing
3.
First rotor 4a is mounted on one of rotation shafts 2, second rotor 4b is
mounted on the other rotation shaft 2. First and second rotors 4a and 4b are
arranged on the same level. Rotors 4a and 4b have similar structures. For
example, each rotor 4a (4b) comprises two ring-shaped plates 5 which are
spaced apart from each other in the axial direction of the rotation shaft 2.
Gears 6a and 6b made of synthetic resin are, as cooperating means, attached
to lower surfaces of first and second rotors 4a and 4b. The diameters of
gears 6a and 6b are identical but larger than those of rotors 4a and 4b.
Gears 6a and 6b mesh with each other. First and second rotors 4a and 4b are
thus rotatable in opposite directions in a cooperating manner. In FIG. 1,
reference numeral 7 indicates support arms for supporting first and second
rotors 4a and 4b.
For example, 16 magnets are arranged at regular intervals on a peripheral
portion of first rotor 4a. These magnets are secured between two ring-shaped
plates 5. In this embodiment, among the 16 magnets, one is electromagnet 9a
(see FIG. 2), and the others are permanent magnets 8a. FIG. 2 shows only
some of permanent magnets 8a.
As shown in FIG. 3, permanent magnet 8a comprises case 10, and a plurality
of rod-like ferromagnetic members 11 housed in case 10. Ferromagnetic member
11 is, for example, a ferrite magnet. Ferromagnetic members 11 of each
permanent magnet 8a are arranged such that ferromagnetic members 11 have the
same polarity at one end. In first rotor 4a, for example, an N-polarity end
portion of each permanent magnet 8a faces radially outward, and an
S-polarity end portion of magnet 8a faces radially inward. As shown in FIG.
2, when each permanent magnet 8a is located between two shafts 2, angle C
formed by longitudinal axis A of magnet 8a and imaginary line B connecting
two shafts 2 is, for example, set to 30.degree. C. On the other hand,
electromagnet 9a is, as shown in FIG. 4, constituted by U-shaped iron core
12, and coil 13 wound around core 12. Electromagnet 9a is arranged such that
both N- and S-polarity end portions face radially outward of first rotor 4a,
and the above-mentioned angle C is formed, similarly to the case of
permanent magnet 8a.
The same number of permanent magnets (8b,9b) as the total number of all
permanent magnets and electromagnet (8a,9a) of first rotor 4a are secured on
a peripheral portion of second rotor 4b at regular intervals. In FIG. 2,
when first and second rotors 4a and 4b are rotated in opposite directions,
each permanent magnet of second rotor 4b periodically moves toward and away
from the corresponding one of the magnets (8a,9a) of first rotor 4a.
The permanent magnets (8b,9b) of second rotor 4b will now be described in
greater detail. Permanent magnets 8b of second rotor 4b, which periodically
move toward and away from permanent magnets 8a of first rotor 4a in
accordance with the rotation of rotors 4a and 4b, have a structure similar
to that of permanent magnets 8a of first rotor 4a. The polarity of that end
portion of each permanent magnet 8b which is located radially outward from
second rotor 4b, is identical with that of the end portion of each permanent
magnet 8a of first rotor 4a. That is, the radially outward portion of each
permanent magnet 8b has an N-polarity.
Permanent magnet 9b of second rotor 4b, which periodically moves toward and
away from electromagnet 9a of first rotor 4a, has a structure shown in FIG.
4. Permanent magnet 9b has a structure similar to that of permanent magnets
8a. Both polarities of electromagnet 9a face radially outward from first
rotor 4a. Permanent magnet 9b has two different polarities which face
radially outward from second rotor 4b and correspond to both polarities of
electromagnet 9a.
As shown in FIG. 2, when each permanent magnet 8b,9b is located between two
rotation shafts 2, angle E formed by longitudinal axis D of the magnet
(8b,9b) and imaginary line B connecting two shafts 2 is, for example, set to
56.degree. C. In addition, when rotors 4a and 4b are rotated in opposite
directions, as shown by arrows, the magnets (8a,9a) of first rotor 4a move a
little ahead of the corresponding permanent magnets (8b,9b) of second rotor
4b, in a region in which both magnets (8a,9a; 8b,9b) approach one another.
In other words, the phase of rotation of the magnets (8a,9a) of first rotor
4a advances by a predetermined angle in relation to the permanent magnets
(8b,9b) of second rotor 4b.
As shown in FIG. 4, electromagnet 9a of first rotor 4a is electrically
connected to drive circuit 14. Drive circuit 14 includes a power source for
supplying an electric current to coil 13 of electromagnet 9a. While rotors
4a and 4b rotate, drive circuit turns on electromagnet 9a upon receiving a
signal from first sensor 15 only when electromagnet 9a and permanent magnet
9b are in a first region in which they periodically approach each other.
First sensor 15 is an optical sensor comprising a light-emitting element and
a light-receiving element. As shown in FIG. 1, first sensor 15 is attached
to a portion of frame 1 above first rotor 4a. First sensor 15 emits light in
a downward direction. The light is reflected by reflection plate 16
projecting radially inward from the inner edge of first rotor 4a. First
sensor 15 receives the reflected light, and feeds a signal to drive circuit
14. Thus, drive circuit 14 turns on electromagnet 9a.
The circumferential length of reflection plate 16 is equal to that of the
above-mentioned first region. When magnets 9a and 9b enter the first region,
first sensor 15 is turned on, and when they leave the first region, first
sensor 15 is turned off. When drive circuit 14 receives a signal from first
sensor 15, it excites electromagnet 9a such that both polarities of
electromagnet 9a correspond to those of permanent magnet 9b of second rotor
4b.
Drive circuit 14 is electrically connected to switching circuit 17. When
brake switch 18 is operated, switching circuit 17 reverses the direction in
which an electric current is supplied to electromagnet 9a. When the current
supplying direction of drive circuit 14 is reversed, drive circuit 14
excites electromagnet 9a only in a time period in which drive circuit 14
receives a signal from second sensor 19. Second sensor 19 has a structure
similar to that of first sensor 15, and is attached to frame 1 so as to be
located closer to the center of rotor 4a than first sensor 15. Reflection
plate 20, which corresponds to the position of second sensor 19, is formed
integral to an inner edge portion of reflection plate 16. As shown in FIG.
2, compared to reflection plate 16, reflection plate 20 extends in
rotational direction of first rotor 4a, indicated by the arrow.
The operation of the above-described magnetic rotation apparatus will now be
explained with reference to FIG. 5.
In FIG. 5, rotation shaft 2 of first rotor 4a is denoted by 01, and rotation
shaft 2 of second rotor 4b is denoted by 02. Only the radially outward
polarity, that is, N-polarity, of the magnets of rotors 4a and 4b is shown,
for the sake of convenience. Although electromagnet 9a and permanent magnet
9b have both polarities located radially outward, only the N-polarity
thereof is shown.
When first and second rotors 4a and 4b are put in a position shown in FIG.
5, magnetic pole Nb1 of one permanent magnet of second rotor 4b is located
in a line connecting shafts 01 and 02. In this case, polarity Na1 of first
rotor 4a, which is paired with polarity Nb1, is a little advanced from
polarity Nb1 in the rotational direction of first rotor 4a. For example, as
shown in FIG. 5, magnetic pole Na1 is advanced from polarity Nb1 by an angle
of X.degree.. Polarities Na1 and Nb1 exert repulsion force F1 upon each
other along line L. Supposing that an angle, formed by line M, which is
drawn from shaft 01 perpendicularly to line L, and the line connecting
shafts 01 and 02 is represented by Y, and that the length of line K is
represented by R, torques Ta1 and Tb1 caused by repulsion force F1 to rotate
first and second rotors 4a and 4b can be given by:
Ta1=F1.multidot.R.multidot.cos (Y-X)
Tb1=F1.multidot.R.multidot.cos Y
Since cos (Y-X)>cos Y, Ta1>Tb1.
As shown in FIG. 5, since magnetic pole Na1 is advanced from magnetic pole
Nb1 by angle X.degree., first rotor 4a receives a greater torque than second
rotor 4b. Thus, first rotor 4a forwardly rotates in the direction of the
arrow in FIG. 5.
Mention is now made of paired magnets of rotors 4a and 4b in the vicinity of
magnetic poles Na1 and Nb1. Magnetic poles Nan and Nan-1 of first rotor 4a
are advanced ahead of magnetic pole Nal in the rotational direction.
Magnetic poles Nan and Nan-1 receive a torque produced by a repulsion force
acting between magnetic poles Nan and Nan-1 and corresponding magnetic poles
Nbn and Nbn-1. In FIG. 5, magnetic poles Nan and Nan-1 receive a smaller
torque, as they rotate farther from the location of magnetic pole Na1. It is
well known that a torque of first rotor 4a, which is caused by a repulsion
force acting on magnetic poles Nan and Nan-1, is decreased in inverse
proportion to the square of the distance between paired magnetic poles Na
and Nb.
Magnetic poles Na2 and Na3, behind magnetic pole Na1, receive a torque which
tends to rotate rotor 4a in the reverse direction. This torque is considered
to be counterbalanced with the torque acting on magnetic poles Nan and
Nan-1.
In FIG. 5, attention should be paid to the region of magnetic poles Na1 and
Na2. As first rotor 4a forwardly rotates, the direction in which a torque
applies to magnetic pole Na2, is changed from the reverse direction to the
forward direction, before magnetic pole Na2 reaches the position of magnetic
pole Na1. The torque for forwardly rotating rotor 4a is larger than that for
reversely rotating rotor 4a. Therefore, first rotor 4a is easily rotated in
the direction shown in FIG. 2.
Second rotor 4b is considered to receive a torque in a direction reverse to
the direction shown in FIG. 2, as seen from the description of first rotor
4a. It is obvious that second rotor 4b receives a maximum torque at the
position of magnetic pole Nb1. As seen from the above formula, torque Tb1
applied to second rotor 4b in a direction reverse to that denoted by the
arrow is smaller than torque Ta1 applied to first rotor 4a in the forward
direction. The rotation of first rotor 4a is transmitted to second rotor 4b
through gears 6a and 6b. By determining the relationship between the
strengths of torques Ta1 and Tb1, second rotor 4b is thus rotated in a
direction reverse to the rotational direction of first rotor 4a, against the
torque applied to second rotor in the direction. As a result, first and
second rotors 4a and 4b are kept rotating, since a torque for rotating
rotors 4a and 4b in a cooperating manner is produced each time magnetic
poles Na of first rotor 4a pass across the line connecting shafts 01 and 02.
In a diagram shown in the right part of FIG. 5, a solid line indicates a
torque applied to first rotor 4a, and a broken line indicates a torque
applied to second rotor 4b. The ordinate indicates a distance between each
magnetic pole and the line connecting shafts 01 and 02 of rotors 4a and 4b.
The first region in which electromagnet 9a of first rotor 4a is turned on is
set in a range of Z during which a torque is applied to first rotor 4a in
the forward direction.
In order to stop the cooperative rotation of rotors 4a and 4b, brake switch
is turned on to operate switching circuit 17. Thus, the direction in which
drive circuit 14 supplies a current to electromagnet 9a is reversed. The
polarities of electromagnet 9a are reversed. The torque applied to
electromagnet 9a in the forward direction is stopped. When electromagnet 9a
approaches permanent magnet 9b, a magnetic attract:on force is produced. As
a result, the rotation of rotors 4a and 4b is effectively slowed down and
stopped. Since the second region, in which electromagnet 9a is excited, is
larger than the first region, a large braking force can be obtained from a
magnetic attraction force.
In the above embodiment, since electromagnet 9a is excited only in a
specific region, a large electric power is not required. In addition, since
electromagnet 9a rotates and brakes rotors 4a and 4b, a braking mechanism
for a magnetic rotation apparatus can be obtained without having to make the
entire structure of the apparatus complex.
The present invention is not restricted to the above embodiment. With the
exception of the paired electromagnet and permanent magnet, all permanent
magnets of the rotors are arranged such that their end portions of the same
polarity face radially outward from the rotors. However, it is possible that
the polarities of the radially outward end portions of the permanent magnets
are alternately changed. Namely, it should suffice if the polarities of the
radially outward end portions of the first rotor are identical to those of
the corresponding radially outward end portions of the second rotor. The
magnets may have different magnetic forces. Furthermore, an electric power
for exciting the electromagnet can be derived from the rotation of the
rotors or from the revolving magnetic field of the permanent magnet.
Angles C and E are not restricted to 30.degree. and 56.degree.. They may be
freely determined in consideration of the strength of the magnetic force of
the permanent magnet, a minimum distance between adjacent magnets, angle x,
and the like. The number of magnets of the rotor is also freely chosen.
Industrial Applicability
As described above, the magnetic rotation apparatus of the present invention
can be used as a driving source in place of an electric motor, and as an
electric generator.

Everything has its limitations and it sounds like you found the limit for
your Kostov motor. 15 % grade, one mile, 4600 lbs, 45 mph was
probably too much to ask the Kostov to do. High voltage and
high current at the same time has killed a lot of EV motors. A common
scenario is that sparking starts and rapidly grows until there's enough
ionized air around the commutator and brushes that arcs occur between
brush sets of opposite polarity and between brushes and other metal parts.
This phenomenon is called "flashover". I prefer to call it the "great
balls
of fire" effect. As you now know, the destruction can be awesome.
I think 192 volts is too much for a daily driver unless you have a
controller that limits motor voltage as yours apparently does not.

Hey Danny
Jeeez Louise! This has got to be a record for length of POST of info that
could have been just linked to.
This page is familiar to many, if not most on the EVDL.
Been around for quite a while.
Took most of the space in my most recent EV digest. :-)
I have linked to this page for years at my EV links page (in signature line)
Sorry if this harshes your mellow.
But... Jeeez Louise!!!

My most sincere apologies if I caused anybody any trouble.
It was to late to cancel before I realized how large it was.

I WAS a little quick on the trigger there Danny.
I appreciate the fact that you felt that the info was valuable enough to
share with the list.
I admit to being guilty of similar stuff in the past :-)

Hi all,
A few weeks ago, a reporter and camera crew from Sydney's Today Tonight
program interviewed Dr Michael Symons and myself about electric cars.
The hour or so of footage of me and my family doing electric car stuff
compressed down to about 20 seconds in the final segment :-)
So, while I sit back and wait for the film offers to come in, you can
check out the text version of the story at

Steve,,I really enjoyed reading your message, it's a great feeling and makes
you feel good that your alive,,,I feel the same way when I go to the pulls or
car shows with my mini pullers, sometimes I have difficulty just leaving the
gas station or a restaurant,,,so I'm thinkin that an EV puller will do the same
thing...a people magnet...the actual pulling is ONLY half the fun...I find I
spend quite a bit of time educating the public just explaining how everything
works in the sport trying to be a "hooker",,ya know..getting others "hooked"
on the sport ...lol,,,my wife didn't like the sport much UNTIL I bought her a
tractor to pull with (didn't have time to build one then),,now she's the one
pushin me to get goin to the pulls or do some improvements to her pullers,, it
gives me great pride to hear her tell pulling stories complete with gearhead
speak,,, the good times last much longer by sharing the great experiences,,,the
comraderie is nice too as long as ya ain't one of those who are in every group
that are despised...anyway,,thanks for sharing those moments with us,,,i'm
sure a like experience can be had by EV pullers if an effort is
made,,,hey..we're ALL gearheads,,it's nice to see a smorgasboard of variety,,,but ya
won't
know till ya try !!! Geo

Yes, I'm the editor, so send it to me, and I'll format it and create a
question for it (it's a lot like 'jeopardy':-). I'll take charging
protocols for $200, Alex. "This is the voltage most often quoted as the
gassing voltage for lead-acid batteries." ...ummm... What is 2.4VPC?
The 'editor' links on the page will send mail to my home address. I can add
questions, and supposedly, I can now add subheadings as well, though I
haven't tried that yet. It's a strange job - usually there is a lot of work
updating things for about 1 month out of the year, then everything gets
quiet again til the next year.
I thought that was a good subject as well, and copied Lee's response to the
variac charging question and pasted it into the document where I keep
interesting posts.
The reason we have it so that only one person has access is that if everyone
had access, the FAQ would soon become a flaming mess of spam and vulgarity.

dangerous to touch, 130V DC I know is not dangerous to touch. That's why I
was asking the question about the higher DC voltages. I wasn't really
looking for an "Osha" or "UL" statement on this question, just someone who
has actually been shocked by a 300V pack. Although this info is really good
for the newbie to digest and understand.

Sorry to hear about your Kostov , I have one in my work truck and pull a
trailer . I'm running around the same voltage but my t-rex's top battery amp
is under 200 and usually I cruse at around 50 to 75 battery amps, . In the
old days with 120v 400 amp Curtis's ruled the streets a kostov or 9" adc
would seem to live forever (I have 50 k on mime ) . But now 156v 1000 amp is
looking like the " standard " , motor care and knowing how far to push them
is coming into the picture. How hot did your Kostov run after pulling the
hill normally , I can always put my hand on mime and leave it there. Was it
very hot when it smoked , I couldn't see the pictures but that's nothing
new for me as I can't ya ho,

as easy as it is to put a volt/amp meter on the motor I haven't got one
either , but I think I will soon .
I also wanted to check the Grizzly PWM operation at near
> 100%
I use to think my controller was operating at 100% duty cycle as the amp
would fall as the motor reved ( in 2 nd gear) to about 45mph ,then I tried
a t-rex 1000 and saw an easy 55 in the same gear. Before I always though
that when the battery amps started falling I was in 100% controller on , but
now I'm not sure.

2 8"s cost just a little more that the kostov, and I'll bet would hold up
much better , probable be easer on the controller to.
