RE: CA Hardening of Balsa Wood
Hi!
Never ever use balsa for mounting servos!!!! At least not in a glow powered plane. Small electric is another matter
Servos should be fastened to plywood! Nothing else!
Here is a picture of my aileron servo in a Q-500 racer. 3mm plywood used. Holes drilled, then soaked with thin Ca glue , after Ca glue has dried the servo is bolted in place
