Can anybody help.
Some time early in 2006, I came across an on-line source of the old

I posted this question on RC Universe, but have got no response.
I want to reverse a servo with a switch. In other words, when the switch is

Now that I've lived in my new home in the country for a month I figured
it was time to find a place to fly airplanes.  Not being much of a club
joiner, I decided to try out the freshly baled hayfield about 50 yards

on rec.models.rc.air that I have listed are being sold "as-is". There is
nothing wrong with them as they are within a year or so of being shipped ...

too much stuff.

Thanks for looking.

the motors up????

No sharing of actual experiences flying, little talk of whole planes

I would like to change my receiver crystal from channel 25 to channel 12.
