| Post subject: | Governor Setup |
Hi, I am about to setup the governor on my Goblin 380, and have a couple of questions. Firstly, in the max head speed box, is this calculated using 3.7 v per cell, making 22.2 v for my 6 cell lipo? Secondly regarding the gear ratio, my heli has a gear ratio of 5.45, but the Spirit software only goes to one decimal point. I know this is only a small difference but it would be nice to have it as exact as possible. Can this be addressed in a later firmware update? Thanks, Eric. |

Just a bump to see if I can get an answer at some stage. Eric. |

Hi, Max Head Speed is simply value you can get at 100% TC with governor disabled. Yes, it is so small difference that RPM readout is way under the threshold. So it would make zero change in the behavior. |

Thanks for the reply. Regarding the max headspeed figure, obviously one does not actually fly the heli at 100% throttle curve with no governor to see the max headspeed it can achieve! So it must be a calculated value. Which brings me back to my original question, what cell voltage is used in this calculation? I am assuming that it is 3.7v per cell, but would like to confirm before setting up the governor. Thanks, Eric. |

Castle creations use a nominal figure of 3.7v per lipo cell for their gov settings.... |

Thanks for the reply. I think this must be it as 3.7v is usually what is called the nominal voltage. I just wanted it confirmed by the man himself to be absolutely sure. Eric. |

Yes, it is true, because it should be the lowest average voltage during flight. |

Great, I will use this value. Thanks for the reply. Eric. |
