Tail servo getting very hot Hey all. My Outrage BL 9188 is nearly too hot to touch after most flights. I’m using a microbeast on my N5C on an unregulated 2s. The gain is as low as I can get it while still holding. No binding anywhere as far as I can tell.I’m considering it might be vibration. What’s the go to gyro tape nowadays for nitro? |

9188 hate vibration and have a shortened life span.A good mechanical check of shafts, main bearings, tail bearings and engine bearings should be done if you suspect high vibes.Do a hard punch out and see if the tail holds, if not the servo is toast. Also check the frequency your running it at, if it’s too high it can create heat. As for tape, the scotch/3m 411 is the standard but can not solve vibration issues.Tom

Poking around the web, your servo uses a 760 usec wide neutral pulse and it can accept position updates at a maximum rate of 560 Hz.Since your servo centers and goes both directions, it seems you have the correct neutral pulse width setting.I don't know what frame rate you have selected on your microbeast, but I believe the microbeast won't update faster than 560 Hz.You might try backing down to 333 Hz, see if that helps.-----

Turned the frequency all the way down to 165 and it’s not as hot, but still very hot.Also noticed the servo is jumping around a few degrees on the ground once I get the engine started?? It doesn’t kick in flight but it has me concerned now.Was I not supposed to use a beastx for nitro?   |

If it was mine, I'd decommission that servo and thank my lucky stars it gave me warning before failing.My experience lies with going through multiple JR 8900G's. Once they were on their way out, they started getting hot and twitchy. Horizon would always just replace the entire servo when I'd send em' in. |

/Check gain of tail servo.Most of the time, high temp is related to high gain.Try by 5 point in down step...
Fly... Check till wig wag appears... Then 5 point up and leave as it./Saludos cordiales, |

Well, a new tail servo didn't help. Actually might be even hotter than the last one... guess I could have stuck with it. Going to be putting a step down on the tail as maybe straight 2s is too much with all of the vibes and 6v will help keep it cooler. |

Put a 5.2v step-down on it this weekend - MUCH better temp wise and holds just as well. I still think some vibes are creeping up through the servo wires into the beastx and might be causing the remainder of the heat. Time to snuff those out and all should be well.Now I just need to figure out where any excess vibes are coming from |
