I new that Airfoil looked familer
( HN-216)
Funny I got 2 of these F3B Ships from China they look Real Nice
Called a Zoom Glider or Chico in the USA and I just looked it up
and its a HN-216 Airfoil this is on the Zoom Glider Website
I am a test Pilot for these New ships coming in the USA

Hey all, I've been flying slope a lot lately, and as a result, I have been
making a few slope related items. One such item is a ballast slug mold. I know
nobody in their right mind would want to ballast a TD plane, so this is mostly
for you slopers...
I built a batch of these and have a few
Looked like Michael is right. According to Profili, it's VERY similar to
the RG-15. I checked it out at re*sqrt(CL)=100k and 150k. (That is,
equivalent to a sailplane which is at Reynold's number of 100k and 150k
when flying at Cl of 1) The two lines are just about right on top of
each other.
Gentlemen, I would like your feedback on something I created last
season in a bit of a whim. I have been competing at various TD tasks
in the Northwest over the last 3 years. Over this time I have
witnessed far too many launches where the pilot after the fact
admitted that he/she did not turn on
David,
Launching without turning the transmitter on is a symptom of a greater
problem. You must build a routine that you consistently follow each and
every time you launch, otherwise you will make this and a bunch of other
mistakes.
Most of the problems occur if you let yourself be rushed,
Richard, Norbert Habe's database (www.habebert.com) has a little summary data
of all the airfoils he has designed, from HN-003 to HN-1091. The HN-216 is not
included. It's possible that he did design it and it's just not listed, but
it's also possible that some plane manufacturer chose this

My best flights are when I forget to turn on :-

For over 25 years, I used a system that prevented launching unless
both the transmitter and receiver were own. Basically, it was a
capture tow hook that had to be opened by radio to hook the towline
to the tow hook and then latched by radio. It was an EK remote
release tow hook with a pin at
They fly good not great. I would compare it to a heavy RNR late 90's moldie
with a fast airfoil like the RG15. It is not a floater like a 7037 but all in
all would make a great intro to open class due to the cost. Zoom will sell to

Well let's see. I'm at a contest and another pilot on my frequency is

plane to do something or other and instant stripped servos?
Maybe not.

In another 1970's story, Rick Norwood, of the Soaring Union of Los
Angles (SULA), launched a Javelin Open class ship and did an active
zoom-type launch at the top. For those unaware of the Javelin series,
these were rolled plywood fuselage R/E planes with straight dihedral
wings and up-swept
No flying here today -- it snowed 8 last night. My high-school son had a snow
day off school, so we XC skied through the back yards of our neighborhood for
about an hour. Made me envy Skip, Cody, Jim and Dr Dan who can do it all the
time.
sounds like a great day with your son mother nature, glad
to hear it Tony.
(don't get any better then that!)
we've been getting a ton of lake effect snow here in SW Mich.,
getting alot of snowshoeing in, and loving it.
seems we would get 12'' to 18'' of snow, then it melts off completely then
Are these the same guys that had an issue with what end of the chute to use
last week and needed the colored rings?

Guys:
I have really enjoyed the Tree Stories. First, they remind me of the
incredible variety of ways that we as a group have found to screw up process
of launching and flying RC sailplanes.
And secondly, the stories all make me feel a whole lot less stupid than
I normally appear.
I have a Pivot Plus kit in mint condition. $200 and shared shipping.
Pictures available. I could deliver it to the Monroe WA swap meet next
weekend to save shipping. Please respond directly to me.
Thanks,
Dan

On a similar note, when I was learning to fly back in the early 90s in
upstate NY, Bill Johnson the kind gentleman that that was mentoring me, said
to meet him at the flying field one afternoon. As I drove up I watched him
do a beautiful launch with his RES (something that started with an M... :)
It's good to know that others have felt as foolish as I, when several years
ago I parked my brother's Electrasoar in the top of a very large tree. This
airplane had a pretty flat glide as long as the speed was maintained.
Needless to say, I was making a long approach and thought myself well
Capture tow-hooks don't work well with zoom-launching techniques.
Operation of such increases pilot load during arguably the most
critical portion of a sailplane flight, seemingly causing a problem
rather than solving one.
FYI, those older types of (nylon) hooks can bind and not release
Connect the switch to a miniaturized fence charger connected to two metal
bits, right where you hold the plane to launch. You will probably not launch
that way, and you will probably not forget to turn on the tx even when you're
launching some other glider. As long as you remembered to be
I only used either the EK Remote Release tow hook which I converted
to a capture tow hook for models up to 115 inch span such as the
Paragon. These models didn't zoom very well and I could usually do
as well by towing as slow as possible to minimize the amount of
towline reeled in. Nothing

How about a bright LED or strobe light inline with the switch. Mounted under
the wing, even if you don't do the hookup your self, you always look at the
hook.

I just do the KISS(Keep It Simple, S7up1d) thing, wiggle the sticks(
and see the response) before you go!! Haven't failed yet. I did have
battery failure, but not the switch. I did forget to turn them off,
is that count?

Brian, you are right on the spot. KISS is always a better path. Why do we keep
circling KISS while looking for the ultimate fix ?

Nowadays I have a big bright flashing LED in my planes,
which helps when I forget to wiggle the sticks!
And I don't use no switch no more, but electrically-
powered-plane-style banana plugs. Very secure
on and off!
Big Deans would work, too, I guess :-)!
