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

Why? it really depends...

  • Where You are 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

  • You engine is not correctly tuned, ask a better pilot to help You set the engine. Your engine MUST smoke
  • If nothing of the above aply, You may want to try the mods below


  • Change the cooling FAN for a QuickUk
  • Change the cooling FAN for a Correct upgrade.
