RE: ParkZone J-3 Cub RTF
I used the gearbox as the template and traced it onto 1/16 ply. I also epoxied small pieces of 1/16 ply to the left side of the wooden firewall adapter behind the mounting holes and at the top where it meets the boss of the cubs firewall, this was done to give the motor a slight offset to the right. Yes, I'm just using the stock batteries. JT.
