RCGF 10cc BM Small Gasoline Engine | 1.9HP Glow-to-Gas Replacement for 40-60 RC Airplanes
Hero Section: The Glow-to-Gas Revolution Starts Here
Stop wiping slime off your wings and stop paying a fortune for nitro fuel. The RCGF 10cc BM is the engine that changes everything for the .40 to .60 size class. Designed to fit into the same footprint as a standard glow engine, this compact 10cc powerhouse brings the reliability, economy, and clean operation of gasoline to your favorite sport planes and trainers. With 1.9HP on tap and a featherweight design, it’s time to upgrade your hangar to the modern era of gas power.
Why Choose The RCGF 10cc BM?
- The Ultimate .40-.60 Replacement
This engine features a Beam Mount (BM) design, meaning it mounts on standard engine rails just like a .46 or .55 glow engine. No custom standoffs or firewall modifications are needed. It’s a true drop-in upgrade that pays for itself in fuel savings.
- Walbro Reliability in a Micro Package
Small engines can be finicky, but not this one. RCGF has engineered a genuine Walbro Carburetor to fit this micro-gas engine. This ensures consistent fuel metering, easy hand-starting, and a reliable idle at 2000 RPM—something cheap clones simply cannot match.
- Clean & Efficient
Gasoline burns cleaner than nitro. Say goodbye to the oily residue that ruins your covering film and soaks into the balsa wood. Plus, gasoline is significantly cheaper and provides longer flight times per ounce of fuel.
Technical Highlights: Precision Engineering
- High-RPM Performance: Optimized for small props, this engine revs up to 9000 RPM, providing the speed and thrust needed for sport aerobatics.
- DC-CDI Ignition: The included micro electronic ignition module features automatic timing advance. It ensures a hot spark for easy starting and adjusts timing for peak efficiency at full throttle (Supports 6V-8.4V).
- Compact Crankcase: The crankcase is precision-cast to minimize weight (only 466g) while maintaining the structural strength needed to handle the higher compression of a gasoline engine.

Usage Scenario: The Weekend Trainer
You have a classic .46 trainer or a Stick that you love flying. You swap out the messy glow engine for the RCGF 10cc. You fill the tank with a few cents worth of pump gas. Ignition on, flip the prop, and it purrs to life. You take off and fly for 20 minutes on a tiny tank. When you land, you grab a rag, but there’s nothing to wipe off. The plane is clean. You smile, realizing you’ll never buy a gallon of nitro fuel again.
Important Tips & Expert Advice
- Tuning is Sensitive: Small gas engines are more sensitive to needle adjustments than large ones. Make very small adjustments (1/16th of a turn) to the Walbro needles when tuning.
- Oil Ratio: Small engines run hotter and faster. During break-in, use a 25:1 or 30:1 ratio with high-quality mineral oil. Do not go leaner than 30:1 even after break-in to protect the connecting rod bearing.
- Ignition Battery: Since this goes in small planes, weight is key. Use a small 2S LiPo (450mAh - 800mAh) or a lightweight LiFe battery for the ignition to keep the Center of Gravity (CG) correct.
