Good idea truckracer hadn't thought of that. Due to the shape of the firewall and the size of the box I will need do you think a box that will fit my firewall and a larger faceplate that will fit my motor mount would be ok? (The faceplate would be larger than the box where the standoffs will mount)
Reason I ask is the firewall bolts to the fuselage and I can't cover up the mounting bolts with the Motor box.
1/4" plywood heavy enough?
