Hey everyone, i have a modified heng long tiger I and i have deatiled it and i have recently had some trouble out of the boards and turret rotaion. It has the infared battle system and the flach with recoil installed. Just yesterday i cranked it up and the tuurt wouldnt turn left. The board fried and i had to use 1 of my replacements. The turret worked fine with the new baord until 5 minutes ago. I started it up, everything worked, i tiook it outside for a run, and the turret stopped working completely. All wires are connected and all solder points hjave been inspected. I have no idea what the problem is but i was hoping some1 here could help me.


Any advice would be greatly appreciated


Thanks

Check the contacts inside the transmitter.

Tried that but that still didnt work. I cant even get a single response out of the motor to the turret gear. I have changed the turret rotation motor housing and the motor but it still wont work at all.

You may have had a short across the turret rotation motor and it fried the 22 ohm resistor of the Heng long board. These are mounted just to the left of the speed control transistors. Check to see for discoloring. If one looks burnt these are pretty easy to replace.

Í tried that and even put in a new motor and changed to a brand new controller and still no respaonse. I just bought this rx18 board 2 days ago and this is the 1st time ive used it.
