ENGINE INSTALLATION

Screw: You can directly mount the engine on the firewall. We recommend M6 screws for your GP

engine. The firewall should be stiff enough to prevent engine vibrations. Use high-grade 1/4 bolts
with washers and locknuts in the back of the firewall. Make sure your firewall is structurally sound.
Servo: We recommend a high-quality servo for the throttle, as it can ensure accurate and reliable

engine's performance and longevity. To cool the engine, an appropriately-sized air intake is
required. The exhaust outlet should be 3 times larger than the intake. Make sure cool air goes

baffles because they can create turbulent air movements in the cylinder fins, which results in
maximum cooling for an air-cooled engine.
Caution: It is important to use seals to prevent sawdust, residual abrasives etc. from entering
