After some fiddling about I couldn't get the tank to work at all so ripped out the electronics
Fitted a Clark TK20 I borrowed from my ZTZ99 tank which is currently in bits
Drilled out the machine gun and added a 3mm red LED
Also changed the red headlights to amber ones.
The original turret turn is slow, so tried swapping with a faster motor and still slow. So ripped it out and fitted a HL turret turn and removed the turn limiter so now is quicker (12 seconds full turn) and fully 360 degree.
Next back onto the lower hull and drive gear. Going to try the ZTZ99 tracks and drive sprockets, but the gap in the wheels is too large and needed closing up.
I cut a load of plasticard to 5mm strips and wrapped them around each side to fill them in.
I then put some rubber (bike inner tube) over it all. And some filing away pinch points.
Tracks fitted to idle wheel
Then onto the gearbox end. Used the battery compartment lid as a base
Cut some plasticard
Also cut the corner off the HL gearboxes
So it wouldn't get in the way of the suspension arm
Gearbox fitted
Removed 3 track links to get this
Finished other side
Now i've only made the idle wheel gap smaller non of the road wheels but took it for a test drive on the grass, and surprisingly the tracks didn't come off.
Next is to add servo recoil, LED flash and hidden battle unit.
