Not only that, but if your plane is ever tilted at that angle as you carry it to or put it into your car, it may turn itself on when you don't expect it, leading to a dead (or worse -- _almost_ dead) battery when you're actually ready to fly. Or it may turn itself on and do damage as the servos glitch because the TX isn't on. Perhaps you could design around this, but then perhaps not all launches would trigger it, if you make it *too* picky? Just wiggle your sticks a little before you launch. (For bonus points, make sure the sticks do the right thing on the plane, every flight!) If it costs a pilot a Gentle Lady to learn this lesson, then they got off cheap! (If it costs them a Pike, well, ouch, but they'll probably remember!) Personally, I've never done it with a glider, but I did do it with a nitro R/C car once. Chasing a R/C car doing donuts at 30 mph in your front yard = fun! All that was lacking was the Benny Hill music! Fortunately, the curb finally intervened to stop the car (and rip out half the screws and bolts in the car in the process ...) If you do decide to make this device, I'd suggest at least adding an audible alarm that goes off when the plane is turned on by it, that runs until the plane is turned on in the proper way (or the battery dies, of course.) That way, people will know that they forgot (and that your device just saved their plane!) when it activates when needed, and they'll know that they need to go turn the plane off again if it activates accidently. -- Doug McLaren, [EMAIL PROTECTED] Gone crazy - back later!
