i do not know much about electric motors. I have the stock tail motor right now, the DD GWS tail motor is in the mail. at this time the stock motor is starting to chatter when it runs. if i apply right full rudder on lift off it will make the motor run smooth, at times in flight the motor will chatter and i will lose alttitude, all the way to the ground unless i can get the tail motor to run correct. then its hard to recover, its all over the place.
Is this what happens when your tail motor is starting to burn out?
I run the birdseed and i am able to power the tail with more current and it will operate correctly.
With the Etex battery, it will not run smooth, i think that is because there is not enough current to over ride or push enough power to the tail.
Can i get a few tips on this problem please
