heng long troubleshootin
hello fellow tankers!! recently purchased the heng long panzer 3 from matomart.com. it has the metal upgrades, gearbox, tracks, etc. after less than one hour of run time the gun barrel started to cycle continuosly. then the turret started to rotate on its own. with the transmitter off and battery on, it does it, so i know ive eliminated the transmitter as the problem. i unplugged the wires for turret function...the tank still drives well though. any ideas?? im thinkin something took a dump in the circuit board...ive heard these boards are fairly flimsy. does anyone make an upgraded board with quality electronics on it...or am i stuck replacing it with more stock heng long hit or miss boards?? thanks for your help
