Mark,
I could not agree more with your commentary on the
decline of full scale soaring. I witnessed some of the
early development of the lead sled era. The first
sailplane I ever saw was a Sisu 1-A in the process of
being built by Len Neime and my brother. The one I sat
in that day now hangs in th

Jim isn't, but I am. I got a Kraft on 50 Mhz when they first came out
with 'em. Boy was that cool. By that time, I had been through hard-tube
superregens, gas-tube rcvrs, compound DeBolt actuators (right, then
left, then up elevator -- s
I got some great ideas for fool-proofing and full-proofing my winch with
it's dual solenoids. I will be investing in some LED's and resistors shortly.
Thanks for all suggestions.

Greetings!
Can anyone point me at a good source for bell cranks for both 2M and open
class planes?
Thanks,

I am interested in this scale sailplane, does
anyone have experience and where can I get one?
thanks

In 1952, I decided to try radio control, however the only license free
radio was the first Citizenship radio in the 435 MHZ band and far too
expensive for a college student. I began working on a ham license, however
before I finished, the FCC authorized the first citizens band for kits
(27.255).

Fritz, Bill,
I would think having a small 12V light bulb across each solenoid would
work. If they don't both turn on when the pedal is released you know
something is wrong. If both solenoids open both bulbs would be running at
reduced brilliance at about 6V, but if one solenoid failed you would

Check.

I must point out a common experience between us modelers.
The modeling experiences of pilots usually share two commonalities.
1a. When starting out they did so alone and did much rebuilding.
2a. They urge new comers to not make their mistake.
