NGH GF38 38cc 4-Stroke Gas Engine Efficient Gas Power for RC Aircraft

NGH 38CC 4-stroke gasoline engine GF38

Product feature introduction:

1. The piston is equipped with 2 rings, further increasing compression and making some local improvements to the piston. However, the power and speed have not decreased, and there is still a 200 rpm increase. Do you know that the increase in the number of piston rings has increased friction. Start better now

2. The compression ratio has changed and increased

3. The timing of the gears has changed slightly, reducing vibration

4. Change in the method of installing propellers

5. The installation method of the engine has changed, and BEAM OUTING has been cancelled. Thick carbon fiber boards are used for installation and fixation to reduce engine vibration
