Rotor scale 450 AH-6 tail rotor

I got problems. It seems like as I run the heil. I increase the speed i.e rotor speed, the tail rotor sometime just stop spinning. What am I doing wrong?

what mechanics are you using and the drive system to the tail?

I have the RotorScale 450 helicopter. Tail rotor is belt driven. The main motor is 450L 1800kv Brushless motor. I have no other info on the tail rotor. Thank you for answering.

are you running 3s or 6s battery with that motor?

First thing you need to do is check the belt is tensions. If its too loose it can loose engagement
