Info:

  • Important, YS engines are designed to run a minimum of 20% nitro but Probuild & YS highly recommend 30% nitro for best operation unless otherwise stipulated in the YS Manual. Both YS & Probuild recommend Model Technics Bekra 30% mix.
  • It is extremely important to get the correct gear ratio in your helicopter because incorrect gear ratio can damage your engine.
  • On the last flight of the day a fuel line clamp should be used to stop the engine in order to prevent rust & corrosion.
  • The Hatori 2123 Is The ONLY Pipe Recommended & Designed By YS For The YS120SR
