so when you opened the case and pluged it it.. it didnt stop turning.. (I am guessing your output gear wasnt attached.. and then that continous turning is normal
If the case was closed and still it was continoulsy turning inside.. then you are looking at a stripped gear... put it back together if you havent already and then put a servo arm on it and move it.. have to use too much force compared to the other servos.. or is clicking.. you got a problems.. depending on what is happeing then...
let us know what you are seeing. If you are using align 410m servos then bro believe me on this, this heli has a 100 times better servos that the blade 450..what servo is this?
410's are great... replace all to those.. you'll have lesser issues
Just keep the Cricket bat away from the heli or you will destroy them in an instant![]()
I would put the gyro in DIR mode and make sure your servo arms are all at 90º to the links at mid stick in idle up. Any time you make a change to the helicopter, this should be the first thing you do. Not all servos are created equal and the pot in the servo that measures center may be just a bit off from the other ones. So one servo's center will not the the other's center. I hope that makes sense lol.
I would also recheck your pitch both positive and negative to make sure they are the same as well.
Are you sure your swash is level? In the second to last pic it looks like the swash is tilting to the back and maybe to the right just slightly. But a LOT to the rear. Where are your pots set on the gyro? You may not have enough gain in the ele and ail.
