Fellow KR heads;

Does anyone know where I can get a replacement stator ring alternator for the 
Great Plains Diehl accessory case?
The Great Plains web site looks like it’s no longer available?
Did they go out of business?
Also would like to find a replacement rectifier for this set up.
Any help appreciated to locate these items.

Re: KR> Muffler

 Hi Stef,
You may want to read Eduardo Barros's web page where he installed a Rotax 912 
engine in his KR2S and made his own muffler.
His plane is featured on the Facebook page - Rand Robinson KR2.  Eduardo Barros

 Hi all

In the Netherlands we have to do a noise test. This year I have to do 
itcost will be 600 euro. And if you are to loud with your plane you have to 
do it again...and pay again..grgrgrgr. A few guys from the air field told me 
that our plane is making a bit more noise than normal. So I need to design an 
muffler. I have surged on the internet but there is a lot information. I think 
to make a turbo muffler (strange name) so I have to design something. 

My easiest fix is to install my catilisator again. Before the first flight I 
removed it to save some weight an this cat gives Also a lot backpressure. On 
the end off the system I have the original BMW muffler (absorber). My idea is 
to design a turbo muffler instead of the catalisator.

 

Is there someone in our KR family who can help me to design something?

The engine sound is 6500 rpm sound.

The lenght I can easily use is 12/ 13 inch. If I go longer I think I have to 
install the Muffler outside the cowling. That is not what I want.

http://www.masttotaalconcept.nl/kr2/styled-27/index.html

The link above you will see at 3/4 from the top my exhaust system ( at this 
moment the cat is not there and it is only a tube). The last muffler is the 
original BMW type.


Hope someone off you have some tips for me.

Re: KR> Engine mount

[CHRIS GARDNER via KRnet]

Leif,Pressure relief holes are not needed in your engine mount unless you plan 
on having it “normalized” after welding to relieve stresses.I wanted to do that 
after TIG welding but forgot to vent each tube beforehand.The temperatures used 
to normalize or stress relieve the mount would cause them to burst if not 
vented.Anyway no issues with cracks in spite of omitting that process.Your 
decision.CheersChris Gardiner

Re: KR> Max gross weight.

[CHRIS GARDNER via KRnet]

Stef,Mine (kr2s) is certified at 1150 lbs max gross weight in Canada. I’m not 
aware of any with a higher gross weights. I used some statements from US KR 
owners that have 1200 lbs or higher to help sell it to Transport Canada.
My KR2S has flaps as per plans ,which factors into the calculation for 
allowable gross weight.My wingspan is also 25.5 feet with larger 
wingtips.CheersChris GC GKRZ

Re: KR> aileron balancing

[CHRIS GARDNER via KRnet]

Jeb,
I cast my lead weights using an empty tin can that was approx. the right shape 
( Tin of hereford corned beef , as I recall) . It was a rectangle with rounded 
corners that seemed the right shape.
The lead was heated in a cast iron skillet frypan , outdoors,  on my camp stove 
( Propane or Naptha type) on a warm summer day. These are cheap skillets for a 
couple of bucks.
Carefully pour the molten lead into the can on a concrete floor . After it 
cools , cut away the can and drill and carve the lead block down to the 
finished weight needed. Dispose of the skillet never to be used again.

Subject: Lead aileron castings

To whom it may concern;

I calculated the size/weight needed then made a mold using plaster paris of 
that calculation.

I heated the mold in the oven to prevent steam explosions prior to pouring the 
liquified lead into the mold.

Once the mold was heated to 450 degrees I poured the melted lead (using proper 
face shield, gloves, and full body heavy clothing to cover all exposed skin 
surfaces) into the mold and let cool.  I then shaved the lead weights using a 
sure file to get the weight to the exact amount needed to counter the aileron 
and perfectly balance it.

Be very careful when pouring molten lead into plaster molds that the mold has 
been sufficiently heated so that all water is gone or it WILL EXPODE in your 
face throwing molten lead in all directions !

Another alternative is to use heavy paper/cardboard to form a square mold to 
pour the molten lead into, the sides can be taped together using ordinary 
masking tape, several layers, without the tape burning through until the lead 
solidifies.  I have used both types of molds.

Hope this is of some help

Re: KR> Fuel header tank

[CHRIS GARDNER via KRnet]

Deon,
CG shift with the header tank is a non -issue. I have a 12 US Gal. header tank 
from RR in my KR2S and the change in trim from full to almost empty is only a 
couple of bars on the trim indicator .
Aluminum is probably superior in chemical resistance from auto fuels and less 
likely to leak than fibreglass. I would keep it . Not sure there is any safety 
issue with it? Lets face it , sitting behind 12 gals of gas in a wood airplane 
is inherently dangerous to begin with . Don't lose any sleep over it.
Cheers

KR> Carbeuretors

I have had good success using the speedometer cable style adjustment on my 
Zenith carb.

With 238 hours to date, I have not had any issues with this method.

Looks a little unconventional but works fine.

KR> Rudder pedals

[Chris Gardner via KRnet]

Phil.
I would definitely recommend going up a few sizes on wall thickness (.058) on 
the rudder tubes as I bent them twice trying to stop on a short runway.
The right hand one is really the culprit not so much the left one due to the 
torque you can apply when the adrenaline starts flowing and the end of the 
runway is near.
I actually ended up re-enforcing the lower corners with an internal tube to 
strengthen the weld and torque points to stop it from bending.
The rudder pedals were one of the surprising things that I did not expect to 
have any problems with yet it was an ongoing issue until the third set were 
made as above.
Contact me directly if you need more details.
