I ahve a delta of my own design with TT 36 Pro and throttle pipe with a 8*8 prop that eats up the sky except this sunday when it bit the dirt and cartwheeled down the runway after a hand launch.

Moral of the story damb on of switch to close to hand hold result palne switched off on launch... result bust prop and leading edge to repair... good job I build em strong.....

Lesson learnt put the on of switch in a less vulnerable spot away from my big fingers.....

I did that once to a glow powered glider of mine....

....accidently turned off the switch at hand launch. (RIP) []

Bummer, sorry to hear about your crash. I've done the same thing at least once

Try installing the switch so that "on" is to the rear. Works for me.

will....

....that's the problem. When you throw the plane, your hand moves the switch
forward.... to "off". []

Ok, let's hear it for a vertical switch

Yep thats what I had a pull out for on and a push in for off...will move my switch out of the way....you fly you crash and you learn.

That happened to me asweal, with a thunder tiger ehawk1400, hand lauched it and nocked the switch. It glided well for a bit until the wind lifted the right wing and sent the thing into a tree, not much damage though

Bless the soft leafs
