Hello again.
Now I present to you the modification of the lifting mechanism gun barrel Heng Long tanks.
Remote control does not change
All changes in the motor control circuit inside the tank.

?? Don't get it what exactly did you do?
Did you make the gun go up and down with the RX instead of cycle up and than down?

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.

How did you accomplish this?

one relay with two pairs of contacts on the circuit-breaking
I switch it relays a signal rise gun barrel
commutating voltage motors turret
the left stick left-right - the relay is normally closed, the wires to rotate the tower through the relay goes to the motor turret
the left stick down - the relay throws these wires to the motor hoisting gun barrel
the left stick is not picking up a left-right - in a closed relay contact voltage turret - the motor lifting gun barrel
In parallel coil relay - a diode in reverse polarity to the supply voltage
