I bought this seconmd hand helimax novus cp heli. The problem I had was that when I increase the throtle the heli start to rotate like crazy to left. I tried to
follow the manual to correct this deviation as was written in the manual :
"E-Board Adjustments The Revolution Mix adjustment controls how much tail rotor is mixed when throttle is increased or decreased. If you find the model rotates to the left when climbing please increase the adjustment
by turning the dial towards the “+”. If the model rotates to the right when climbing then decrease the adjustment by turning
the dial towards the “-”"

but the heli continue to rotate like crazy to the left so I the heli can not stay on the ground.


1. Is there a way to return the heli reciever to factory default.
2. What should I do to overcome this problem?

All dip switches in the transmitter are in the defualt state.

Please advise.

I found the problem. The problem is binding between the tail rotor and the tail rotor motor shaft. for some reason the binding between the two was weak so the tail rotor rotate relativetly slowly. after I glue it. the problem was solved.
