Anyone had issues with the stock speed control? Ive only flown my aircraft once and it worked great. I bought some lipos and also had some for my heli to use but when I put the esc into lipo mode it surges and pulses above 80% throttle all the way to 100%. i talked to horizon and they said it was the batteries but if I try it in lipo mode with the stock battery it does the same thing. When I put it back to regular mode it acts normal with any battery. Horizon said to send it back and id rather not if its a setting issue.Any help would be greatly appreacated, Thanks
