Both tow hook and CG changed accordingly. With 20m bungee and 100m nylon cord the glider reached 63m having 16km windspeed. Can I have better results? The CG looks correct because gliding is perfect. Do I need to have the hook more to the front or aft to reach more height? 20230429_134118_1.mp4

Hello guys, I am new on this topic. I bought myself a nice present on Marktplaats being an Edmund Halton Special glider. I am surprised how easy to fly this model. However I am having problems with the start. Reaching a height of 20m the glider disconnect from the line. The theory about this issue seems to be a rearwords position of the release hook. I have not yet changed the original releasehook (the triangle plywood hook). I have the following questions: - What is the best location of the releasehook? - What is the location of the C.G.? - Is the constuction drawing still available?
