Having some stability issues on my D-130 X8
In light wind or (as today) in suspected thermals it gets very unstable Scary on a 10 000Usd rig!!
If I compare Roll des roll and Pitch Des pitch it has a big gap right betore i aborted the mission and climbed accidentally over 120 m fence in stab mode... between the both...
I have manually tuned the D-130 and it is VERY stable in STABILIZE mode but as nov in AUTO or RTL mode it becomes very wobbly!! I have also lowered the CG by moving the lipos to below center plate. Got somewhat better but still scares the sh..t out of me when it starts wobbling in any autopilot mode... Maybe i have to lower the nav gains on this big bird??? Or what??
Please tell me what to do. :-(
