Help Needed: Tailsitter “Tornado” Spin (CCW)
I’m struggling with a persistent Counter-Clockwise (CCW) spin on my tailsitter during hover. The tornado has reduced with tuning, but the CCW rotation won’t stop.
My Setup:
-
FC: Matek F405-Wing V2
-
Firmware: ArduPilot
-
Frame Weight: 700g total
-
Motors: 2207 2550kv
-
Props: 5-inch
-
Compass: None (Running compass-less)
-
Wiring: Motors on S1/S2, Elevons on S3/S4
The Problem:
As soon as I throttle up to lift, the plane spins CCW (viewed from the nose). I’ve verified motor directions and stabilization movements, but I can’t get it to hold heading.
Does anyone have experience with compass-less tailsitter tuning on high-KV motors? Any help would be appreciated
