RCGF 26cc BM Single Cylinder 2 Stroke Gasoline Engine | 2.5HP High RPM Replacement for 1.20 Glow Engines
Hero Section: The Ultimate Glow-to-Gas Conversion
Say goodbye to expensive nitro fuel and messy cleanup. The RCGF 26cc BM is designed to be the perfect drop-in replacement for 1.20-size glow engines. Featuring a standard "Beam Mount" design, it fits easily onto existing engine mounts without complex modifications. But it’s not just about convenience; with a screaming 9000 RPM redline and 2.5HP, this engine breathes new life into your sport planes, warbirds, and 3D models. Enjoy longer flight times, cleaner airframes, and the reliability of gasoline power.
Why Choose The RCGF 26cc BM?
- Compact Powerhouse (High RPM)
Don't let the size fool you. This compact engine revs higher than its big brothers, hitting 9000 RPM. This makes it exceptionally good for speed planes and warbirds that need high prop speeds. Weighing only 740g, it keeps your plane light and agile.
- Easy Installation (Beam Mount)
The "BM" stands for Beam Mount. Unlike larger gas engines that require standoff mounts, this engine mounts on rails just like a traditional nitro engine. This makes converting your favorite .90 to 1.20 size aircraft to gas power incredibly simple.
- Reliability Standard
We don't cut corners on the core components. Equipped with a genuine Walbro Carburetor and NGK-CM6 Spark Plug, the RCGF 26cc offers easy hand-starting and a reliable idle. The Walbro carb ensures consistent fuel metering in all flight attitudes, from inverted passes to vertical climbs.
Technical Highlights: Precision Engineering
- High-Efficiency Porting: The cylinder design is optimized for high-speed airflow, allowing the engine to breathe freely at 9000 RPM.
- DC-CDI Ignition: The included electronic ignition module (6V-8.4V) features automatic timing advance, ensuring the spark fires at the perfect moment for maximum power and efficiency.
- Robust Cooling: Despite its small size, the deep cooling fins ensure excellent heat dissipation, preventing power fade during long flights.

Usage Scenario: The Sport Flyer's Upgrade
You have a 1.20-size P-47 Thunderbolt that has been sitting on the shelf because nitro fuel is too expensive. You swap in the RCGF 26cc BM. It fits right on the rails. You fill the tank with cheap gasoline mixed with oil. One flip, and it starts with a crisp 2-stroke ring. You take off, and the 9000 RPM power pulls the warbird through fast, scale maneuvers. You fly for 15 minutes and land with plenty of fuel left and almost no oil residue on the wings. This is the freedom of gas.
Important Tips & Expert Advice
- Propeller Selection:
- Speed/Sport: Use a 16x10 or 17x8 to take advantage of the high RPM.
- 3D/Thrust: Use an 18x8 for better pull-out power (note: this will lower max RPM slightly).
- Break-In: Because this is a high-revving engine, a proper break-in is vital. Run at least 1 gallon of fuel at a rich 30:1 ratio with a smaller prop (16x8) to seat the ring without overheating.
- Ignition Power: Ensure your ignition battery is fully charged. A weak battery can cause the engine to miss at high RPMs (9000+). We recommend a 2S LiPo regulated or a direct 2S LiFe pack.
