Some people like to use the unlimited "mini-start" for this application, but I recommend my standard 1/2" catapult bungee. It's usable tension range is from about 15 to 40lbs. depending on stretch and it will easily launch an open class glider to 100ft. plus with no line. I always recommend at least 25ft. of line just to put you out of the danger range if something lets go! Some people like to use a tape on hook mounted a couple inches forward of the standard hook so the launch becomes a catapult rather than a kite- like histart launch. This method is great for composite planes (glass/foam or molded), I would be reluctant to try it on a built up like an Ava. If you are flying a built up, stick with the normal hook position and use 20' to 50' of line depending on the desired launch height. It will still act as a catapult and really accelerate the plane. If you are flying any plane that can't take a full pedal winch launch, stick to a ministart, the standard bungee will re-kit your plane.
