Hero Section: The Perfect Upgrade for Your Hangar
Is your favorite sport plane ready for a heart transplant? The RCGF 20cc BM (Beam Mount) is designed to be the ultimate game-changer for pilots who love the hobby. Imagine taking your trusted aircraft and giving it the raw power, distinct sound, and fuel economy of a gasoline engine—without the headache of complex modifications. Whether you are a father teaching his son the mechanics of flight or a weekend warrior chasing the perfect vertical climb, this engine brings a new level of realism and excitement to your shared adventures. It’s not just an engine; it’s the roar of freedom on a Saturday morning.
Why Choose the RCGF 20cc BM?
- The "Beam Mount" Advantage: This is the standout feature. Designed with a beam mount configuration, this 20cc engine fits directly into standard mounts used for .60-.90 size glow (nitro) engines. You can convert your plane from expensive glow fuel to affordable gasoline easily.
- Power Meets Efficiency: With 2.5HP packed into a compact frame, this engine generates over 15 lbs of static thrust. It delivers the torque needed for 3D maneuvers and warbirds while sipping fuel, allowing for longer flight times and less mess to clean up afterwards.
- Hassle-Free Starts: Forget the frustration of endless flipping. Equipped with a genuine Walbro carburetor, the RCGF 20cc offers reliable fuel metering and easy tuning. Combined with the DC-CDI ignition, it starts easily and runs consistently.
- A Gift of Craftsmanship: For the man who appreciates precision engineering, this engine is a masterpiece of metal. It’s an ideal gift that encourages hands-on problem solving and offers the rewarding experience of tuning a high-performance machine.
Technical Highlights: Expertly Engineered
- Intelligent Ignition: The DC-CDI (Capacitor Discharge Ignition) system features automatic timing advance. This ensures a stable, low idle at 1800rpm for safe landings and a linear power curve all the way to 9000rpm.
- Superior Cooling: The single-cylinder design features deep, optimized cooling fins. This air-cooled system effectively manages heat even during slow, high-alpha 3D flight, preventing overheating and ensuring longevity.
- Robust Construction: Built with a piston valve design and high-quality materials, this engine is sturdier and more precise than many competitors. It is designed to handle the higher compression and vibration inherent in gasoline combustion.

Usage Scenario: The Sound of Success
You are at the flying field, surrounded by friends. You fuel up your plane with a simple mix of gas and oil—no more expensive nitro jugs. You flip the prop, and the engine catches immediately, settling into a deep, throaty idle that turns heads. As you taxi out and push the throttle, the plane responds with authority, pulling into a massive loop. The reliability of the RCGF 20cc gives you the confidence to try new maneuvers, knowing the power is there when you need it. It’s a satisfying day of mechanics, flying, and camaraderie.
Important Tips from the Expert
- Propeller Choice: For most sport flying and warbirds, a 16x6 propeller is the "sweet spot," offering excellent thrust and spool-up speed. For speed, try a 15x8.
- Break-In Procedure: Do not rush this step. Run the engine with a slightly richer oil mix (25/1) for the first few tanks and avoid overheating. A well-broken-in engine will last for years.
- Battery Safety: Ensure your ignition battery is fully charged and isolated from the receiver battery to prevent interference.
