If you want to skip the talking and get to the action jump to 1:30 for the first attempt and 6:45 for the second.
This is the first two attempts at trying to tow and fly a scratch-built 60" wingspan glider that is getting towed up by a short course RC car.
The wing I am using came from a Dyncamic S glider that I crashed beyond repair. The truck we are pulling it with is a Kyosho SC-R. The glider's AUW is around 500g and the car needed a few lbs added so it wouldn't flip.
Had one successful flight with this glider before breaking the poorly designed vertical stab. Check out the attempt here - http://youtu.be/4daBgSHFxh8
