[frazee71]

just got her out this weekend gave her a onceover powered her up. Went forward fine but in reverse it started lunging like something was binding. Went forward again ,smooth, no problems hit reverse again something lunging. Any thoughts would be helpful and appreciated. ( it is a stock gen 8 v2 i bought used) thanks

I would look to make sure everything is tight, nothing moving that shouldn't and make sure their is no binding. After that, have you tried recalibrating the ESC?
