I don't know much about Hitec as i always ran JR in my planes. But i just received the 5765 and it is not a 2.5 screw or the threads was not tapped right. Connected Hitec about it they would not replace servo but did agreed to send me the gear and shaft after three phone calls. Not high on my list of good venders. So my new truck still sits awaiting servo 5 days has passed and mail has ran for the day. I have have the time to break it in just running in the garage.
