RCGF 56cc BM Single Cylinder 2 Stroke Gasoline Engine | 5.5HP 8500RPM High Speed Motor for 50cc RC Planes
Hero Section: The High-Revving Upgrade for 50cc Class
Why settle for standard performance when you can push the limits? The RCGF 56cc BM is the ultimate upgrade for your 50cc class airframes. Bridging the gap between the 50cc and 60cc markets, this engine offers a blistering 8500 RPM redline and 5.5HP of raw power. It fits into the footprint of a standard 50cc engine but delivers the extra punch needed for high-speed warbird passes and explosive 3D pull-outs. It’s lighter, faster, and built to perform.
Why Choose The RCGF 56cc BM?
- Speed Demon (8500 RPM)
Most engines in this size range top out around 7500 RPM. The RCGF 56cc BM screams up to 8500 RPM. This higher rev ceiling translates to higher top speeds and more kinetic energy for tumbling maneuvers. It brings your plane to life with a distinct, high-performance sound.
- Reliability You Can Trust
An engine failure can cost you an airframe. That’s why the RCGF 56cc BM comes standard with a genuine Walbro Carburetor and an NGK-CM6 Spark Plug. These premium components ensure easy starting, a stable idle at 1500 RPM, and consistent fuel delivery even under high G-forces.
- Exceptional Power-to-Weight Ratio
Weighing in at just 1329g (Host), this engine is incredibly light for its output. Yet, it generates a massive 14.5kg (32 lbs) of static thrust. This means you get 60cc-class thrust without the weight penalty, keeping your wing loading low and your flight performance high.
Technical Highlights: Precision Engineering
- BM Series Durability: The "BM" designation signifies a reinforced crankcase and optimized cooling fin design. This ensures the engine stays cool and maintains structural integrity even during aggressive, high-temperature flights.
- Piston Valve Efficiency: Utilizing a proven 2-stroke piston valve design, this engine minimizes moving parts for maximum durability and ease of maintenance.
- Smart Ignition: The included DC-CDI ignition module (6V-8.4V) features automatic timing advance, optimizing the spark for both easy hand-starting and peak RPM performance.

Usage Scenario: The Adrenaline Rush
You taxi your 50cc Edge 540 to the runway. You advance the throttle, and the RCGF 56cc responds instantly, revving quickly to a high-pitched scream. The plane leaps off the ground. You pull into a vertical climb, and the 14.5kg of thrust pulls the plane upward effortlessly. You level off and go full throttle—the 8500 RPM capability pushes the plane to a blistering speed that turns heads at the field. This is what a sport engine should feel like.
Important Tips & Expert Advice
- Propeller Selection:
- For Speed/Warbirds: Use a 22x10. This takes advantage of the high RPM for maximum airspeed.
- For 3D/Thrust: Use a 23x8. This provides better low-end bite for hovering and harriers.
- Break-In Procedure: High-RPM engines need a good break-in. Run at least 2 gallons of fuel at a rich ratio (30:1) using non-synthetic oil. Avoid holding full throttle for long periods during the first few flights.
- Cooling: Ensure your cowling has sufficient airflow. The air exit hole should be 3 times larger than the intake to prevent the engine from overheating at high RPMs.
