• Symptoms:
    • Engine overheating
    • Loss of power even if the motor smoke a lot

    Why? it really depends...

    • Where You are living....in the desert? do not forget that some gyro may have trouble too and may drift a lot if the day is too warm (more than 35°C). In altitude, less oxygen -> more nitro
    • The percentage of nitro/oil the more oil/nitro the cooler the engine will run -> Attention here in europe, nitromethan can cost an arm and and leg -> 30euro/liter !!! at 15%nitro. I personaly usually fly with 1% nitro! enough for learning.
    • You engine is not correctly tuned, ask a better pilot to help You set the engine. Your engine MUST smoke
