RE: Blade SR120 Spinning Problem
Have you adjusted the rudder trim? If you are using the stock transmitter push the trim buttons until you have the rudder trim centered then try that. I think you mean the heli is spinning on its axis, or spinning around the main shaft. If the rudder trim does not make any change then either your tail motor is bad or the 5 in 1 board has a problem. If the heli is fairly new, call HH as they have a good customer service rating. But do check over the trims first.
