GP-61 is designed for a power maximum of 9000 RPM. We recommend that you do not use

propellers that turn the engine on the ground at more than 7700 RPM. Do not forget that the

balance of your propeller is absolutely critical to the health of your engine.

Fuel and Oil Mix

Always use 40 to 50 volume units of unleaded 89~93 octane fuel mixed with 1 unit of synthetic

oil (40~50: 1). We recommend Red-line Two Stroke Racing Oil and Motul 710. These oils are

easy to find at most motorcycle stores. Oil used in cheap garden appliances and synthetic oils

are not intended for methanol model machines and must not be used. Any damage resulting

from the use of low quality fuel is not the responsibility of GP Engine. Do not use mixed fuel

that is more than 90 days old.

Screw: You can mount the engine directly to the firewall. We recommend a M5 screw for GP-

61, M6 for GP-123, GP-88 andGP-176. The firewall should be stiff enough to prevent engine

vibrations. Use high grade 5mm or 6mm with washers and locknuts in the rear of the firewall.

Make sure your firewall is structurally sound.

Servo: We recommend a high quality servo for the throttle, as it ensures accurate and reliable

throttle operation. We also recommend a high quality servo linkage. Do not use all metallic

servo linkages, as this could cause radio interference.

Fuel Tank: We recommend a 450cc-500cc fuel tank for GP-61, a 800cc-1000cc fuel tank for

GP-123 & GP-88 models, and an approximately 1500cc one for GP-176. The tank must be

vented, and the vent should be routed to the outside of the plane, preferably at the bottom of the

cowl.

Engine Cooling: Sufficient air circulation under the cowl must be ensured, as cooling is

important for the engine's performance and longevity. To cool the engine, an appropriately sized

air intake is required. The exhaust air outlet should be 3 times larger than the intake at the bottom

rear of the cowl for the hot air to exhaust. Make sure cool air can go through the cylinder fins

and does not bypass them and rake an easy route to the exit. It is better to build baffles, as this

can create turbulent air movements through the cylinder fins, hence providing maximum
