Engine Bolts and Firewall Requirements

The KAVAN AP06 should be mounted to a glass filled nylon motor mount or to an integrated wood beam mount built into the fuselage structure of the aircraft. Use M2.5 socket cap screws, washers and locknuts to mount the engine to the motor mount. If using a glass filled mount, the firewall 3 in the airplane should be aircraft grade plywood no less than 3 mm (1/8”) thick. The firewall should also be reinforced to meet the torque and power of the engine.
