RE: modification of the lifting mechanism gun barrel Heng Long tanks.
I have not changed any RX-18 or the lifting mechanism gun barrel. I did not change control of the transmitter sticks. But I made it possible to control the angle gun barrel is not cyclic. The only difficulty - is the passage of the extreme positions of the barrel. Not yet put the stopper rotation gearbox - so long as I can manage both the cycle and not on a cycle.
