Plane pithching up and down in rth mode. #10213
Comments
The bigger problem is that it's in failsafe, not RTH.
You want to check all of that before touching PIDs. |
Ok i will try it and see if it works. |
Well it is in RTH but triggered via Failsafe mode I assume. If you want to use RTH just trigger RTH mode directly, don't do it via Failsafe mode. Failsafe mode is really just to check Failsafe is working as expected, it's not a mode to use normally. |
The throw is ok and servos centre correctly. There might be a problem with my control linkage beacouse it is just a thin steel wire, its pretty stiff but it bends a little when the servo is at max throw. Also I will try to run auto level trim today. |
How much throw is max throw? What airframe is it? |
It is a custom made airplane. Max throw is around 1 or 2 centimeters. |
Between 1 and 2 cm. You mean it can vary between 1 and 2 cm. If so, that is a big problem. 2 cm could be a lot of throw. Depending on how big the aircraft and wing is. |
Sorry for miss Information but today I mesured my throws to be shure. The exact value is 5mm of throw on the elevator. |
I've had a similar issue with running a waypoint mission - see video https://www.youtube.com/watch?v=N0CbEymUxSM |
I'm also getting this issue during rth and cruise. Any other flight mode is perfect |
Which version of INAV were you using ? |
7.1.1 |
Here is the HD video of this waypoint mission as it has sound you can hear the motor ramping up and down... |
