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.
