Seems like the 120A KDS ESC was causing serious wobbles on fast forward flight. So strange. No matter how low gains I set on BeastX I still had those wobbles. I then switched back to my trusted 100Amp Hobbywing ESC and everything gets back to normal. Guess I will have to keep my bad boy this way. It's a great 3D helicopter and I simply love its performance. Comments and feedback welcome at [email protected] , [email protected] or [email protected] Don't forget to visit , and Subscribe to
