Tomas, I have mechanically matched my throttle servo output, tx endpoints, subtrim and throttle range on the diagnostic page. 0% would represent a fully closed throttle and the engine won't run at this setting. I'll need roughly 10% throttle to idle the engine. How should this be set? I see one option is: to reset 0% throttle so the engine is at idle at 0% and full speed at 100% and then use a mix to cut the throttle (which would then show as -10% on the diagnostic tab). Is that the right way to set it up? Is there another way? Thanks, Scott |

You can normally set 10% in the transmitter for idling. It can be done in the very same way as you have did with for example receiver. Second option is also possible, but first one is easier from my point of view. |

Thanks for the reply. If as in the example, I was worried that I'd be too close to the percentage where the governor would kick in. 15% seems like a very low throttle percent for the governor to engage. I'm worried that the gov will engage accidentally. |

Oh, you have not mentioned that you will be using governor too. If you will not exceed certain value, it can't engage on its own. We are doing lot of improvements in the governor to make it easier especially for Nitro/Gasser helicopters, so it will be strightforward. |
