RCGF 32cc BM Single Cylinder 2 Stroke Gasoline Engine | 3.9HP High Power for 30cc RC Airplanes & 3D Aerobatics
Hero Section: The Perfect Entry into Giant Scale
Step up to the world of gasoline power with confidence. The RCGF 32cc BM is the ultimate powerhouse for 30cc class aircraft. Whether you are converting a glow model or building a new 3D aerobatic plane, this engine delivers the perfect balance of weight and performance. With a screaming 3.9HP output and a lightweight design (only 914g), it transforms your aircraft into a vertical rocket. Experience the thrill of long flight times, the smell of gasoline, and the reliability that only a high-quality 2-stroke engine can provide.
Why Choose The RCGF 32cc BM?
- Class-Leading Power-to-Weight Ratio
In the 30cc class, every gram counts. The RCGF 32cc BM weighs just 914g (engine only) but generates a massive 7.2kg (19.9 lbs) of static thrust. This incredible ratio allows for explosive pull-outs from a hover and unlimited vertical climbs, making it a favorite for 3D pilots.
- The "Gold Standard" Reliability
Forget the hassle of hard-to-tune engines. This model comes pre-installed with a genuine Walbro Carburetor and an NGK-CM6 Spark Plug. These industry-standard components ensure easy hand-starting, a stable idle at 1800 RPM, and smooth throttle transitions without hesitation.
- Compact & Versatile
The "BM" (Beam Mount) design makes installation a breeze, fitting easily into cowls designed for 30cc engines. It’s the ideal powerplant for popular models like the Edge 540, Extra 300, or scale Piper Cubs.
Technical Highlights: Precision Engineering
- Optimized Porting: The cylinder porting is tuned for high RPM performance (up to 8500 RPM), allowing the engine to breathe freely and deliver peak power when you need it most.
- DC-CDI Ignition: The included electronic ignition module features automatic timing advance. It adjusts the spark timing based on RPM, ensuring easy starts and maximum efficiency across the entire throttle range (Supports 6V-8.4V LiPo/LiFe).
- Efficient Cooling: The BM series features deep cooling fins that effectively dissipate heat, ensuring consistent performance even during slow, high-alpha 3D maneuvers.

Usage Scenario: The Weekend Sortie
You arrive at the field with your 70-inch wingspan Extra 330. You fuel up, flip the choke, and give the prop a few turns. Ignition on. One solid flip, and the RCGF 32cc roars to life, settling into a steady purr. You take off, and the plane feels light and responsive. You pull into a hover, the engine holding the plane effortlessly against gravity. When you punch the throttle, the 3.9HP kicks in, rocketing the plane skyward. This is the joy of gas power—simple, powerful, and fun.
Important Tips & Expert Advice
- Propeller Selection:
- Break-in: Use an 18x8 prop for the first gallon of fuel to keep the load light.
- 3D/Aerobatics: Switch to a 19x8 or 20x8 for maximum thrust and braking action.
- Speed: Use an 18x10 for faster sport flying.
- Oil Ratio: For the break-in period, use a high-quality mineral 2-stroke oil at 30:1. Do not use synthetic oil until the engine is fully broken in (approx. 2-3 gallons), as synthetic oil is too slippery for ring seating.
- Ignition Battery: We recommend a 2S LiPo (7.4V) or LiFe (6.6V) battery for the CDI. Ensure it is fully charged to prevent ignition cut-outs.
