OTOH, why not build a foam wing for the model and toss the balsa wing? Yeah, it will set you back some green backs but will greatly reduce the possibility for a failed wing. Chances are good that the end result will be lighter than the balsa stick one. This model is inexpensive enough yet flies well enough as is to where an additional couple 100 won't kill the wallet.
