So I got a used Trex 450 pro and it has been hovering fine since. I have mainly been doing hovering, and mini autos. I did a few pirouettes but nothing hard on the tail. Yesterday I started losing tail control and landed the heli. I then tried to take back off and I had lost all tail control. I looked over and noticed the Torque Tube Drive Gear and the Long Umbrella Gear(On the Tail boom Mount) totally stripped. Main I am so happy I got it on the ground prior to it crapping out.
I have lost two heli dues to Torque tube loosing the gears, this would have been a third
. I think I might start liking belts more
I know I do not know the history of the heli from the prior user, but how long do these gears last?
