A motor mount for a Sig Wonder balsa RC aircraft produced by Sig Mfg. The author states this mount was designed to use the original glow engine firewall screws and provide mounting for a brushless motor. The author reports using a 35-36 1400KV motor with an 8" prop, 3S LiPo, and 60A ESC. In V2, the author removed a 1mm offset to the left so the motor is centered and added more strength to the firewall mounting holes.
