RCGF 35cc RE Rear Exhaust Gas Engine for RC Airplanes 4.1HP High Performance
Hero Section: The Clean Power Solution
There is nothing more heartbreaking for a scale modeler than cutting a massive hole in a beautifully painted cowl to fit a side muffler. The RCGF 35cc RE (Rear Exhaust) is designed to solve this problem while delivering adrenaline-pumping power. By routing the exhaust out the back, this engine allows for a sleek, aerodynamic profile perfect for warbirds and high-performance aerobatic planes. Whether you are upgrading a 30cc airframe or building a new project, this engine offers the perfect blend of aesthetic perfection and raw, 4.1HP mechanical force. It’s time to give your aircraft the heart it deserves.
Why Choose the RCGF 35cc RE?
- Streamlined "Rear Exhaust" Design: The standout feature of this engine. The rear exhaust port allows the muffler (or a tuned pipe) to be hidden behind the engine or routed through a tunnel. This preserves the scale look of your P-51 Mustang, Spitfire, or sleek sport plane.
- Power Upgrade: Don't settle for standard 30cc power. This engine fits in the same footprint as most 30cc engines but punches out a massive 4.1HP. It gives you the extra vertical thrust needed for 3D hovering and aggressive pull-outs.
- Reliability is Key: Equipped with a genuine Walbro carburetor, the RCGF 35cc RE offers easy starting and a consistent, linear throttle response. No more dead-stick landings caused by unreliable fuel metering.
- The Builder’s Choice: This engine is the ultimate gift for the RC pilot who values craftsmanship. It allows for a cleaner, more professional installation that shows off the builder's skill, not the muffler.
Technical Highlights: Engineering Excellence
- Optimized Thermal Management: Rear exhaust engines can run hotter if not designed correctly. RCGF has engineered deep cooling fins and a specialized cylinder head to ensure maximum heat dissipation, keeping the engine cool even during high-stress maneuvers.
- Smart Ignition: The included DC-CDI system features auto-advance timing. It ensures a stable idle at 1600rpm and smooth acceleration all the way to the 9000rpm redline.
- Precision Construction: Built with a robust piston valve design and high-grade metal components, this engine is designed to withstand the high compression and vibration of gasoline combustion.

Usage Scenario: The Perfect Line
It’s a competition day or a busy weekend at the club. You bring out your Extra 300 or Edge 540. The cowl is smooth, unbroken by ugly muffler cutouts. You flip the prop, and the RCGF 35cc RE roars to life with a deep, tuned sound. As you take off and pull into a vertical climb, the extra horsepower is immediately evident—the plane accelerates upward without hesitation. The clean aerodynamics and the reliable power give you the confidence to push your skills to the limit.
Important Tips from the Expert
- Cooling Airflow: Because the exhaust is in the rear, ensuring airflow over the cylinder is critical. Make sure your cowl has proper baffling to force air through the fins, and an exit hole that is 3 times larger than the intake.
- Propeller Selection: A 20x8 propeller is the sweet spot for 3D flying, offering massive thrust. For speed, a 19x10 works well.
- Tuned Pipes: The rear exhaust design makes it very easy to install a tuned pipe (canister) inside the fuselage for even more power and a quieter sound.
