Hi guys,
I am planning on using a catapault to launch my SAPAC L-39. where would you recommend the hook be located on the fuselage?
Thanks,
Ron

I just went through this with my GWS A-4, and the glider fanatic of my club advised me to put it 1-2 inches ahead of the CG. This allows the plane to rotate (as up elevator is applied and you throttle up) and fly off the bungee ring. So far it has worked fine. Kinda exciting watching your plane go from 0 to 60 mph in about 3 seconds!! CC

Hi Just in front of the wing saddel add a bit of ply epoxy it into place screw in your hook and away you go.
