i just remembered that a throwing "lever" could be used to give extra power to the launch of the glider.
like the south american "atlatl" (see picture).
maybe this way the tip of the lever could be molded to fit the glider and not the other way around - minimizing the risks of altering the aerodynamic design of the glider.
Cool idea Cachalote!
If anyone is wondering the pictures shows a man throwing a spear.
The Atlatl is a "holder" for the spear, and that when used (as Cachalote says) will boost the power of the spear.
I think it is a brilliant idea Cachalote, and if the glider already goes really far without one,
Who knows how far it will go with an atlatl! (Probably miles!
)
