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 careful and not hold that spot, you could go ahead and load the thing in the car. Have it turn off after a while if another tilt switch cycle doesn't occur.
Alternatively, you could just hook the switch to a tiny speaker playing emetic music. I'm not sure, though, that the one form of hurling is conducive to the other. On the other hand, the simple way is probably to use a jack switch like the dlg guys use and hook up something really obnoxious to the end of the red streamer. Like a softball on about two feet of string. Or maybe just something heavy enough to pull out the plug when you pick up the glider. ---- Original message ---- >Date: Fri, 1 Feb 2008 14:12:36 -0600 >From: Doug McLaren <[EMAIL PROTECTED]> >Subject: Re: [RCSE] Re: Airfoil flight comparison( HN-216)? >To: Anker Berg-Sonne <[EMAIL PROTECTED]> >Cc: David Webb <[EMAIL PROTECTED]>,[EMAIL PROTECTED],Soaring@airage.com > >On Fri, Feb 01, 2008 at 10:31:59AM -0500, Anker Berg-Sonne wrote: > >> There are so many ways launches can go wrong that your proposed device may >> save you from one problem, but the others will be sure to bite you instead. > >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.
