Hi Holo,

From rc tank divsion in singapore, lurking here most of the time. Decided to post because of the questions on slip rings keep coming up.

I've fitted a 24 wire slip ring off ebay on my HL leopard 2A6. However the configuration is such that the TK22 board remains in the lower hull with the battery. There is no high tension flash and the flash is replaced with an white LED.

The reasoning is the same problem as you have. The slip ring is designed for sensitive signals to be transmitted through it (CCTV video for instance). It is still safer to use the slip ring to carry over servos, MG light, barrel flash, TBU instead of the method you worked.

So far there hasn't been any major electrical/electronic issues concerning the slip ring, although initially issues such as TBU sensitivity, IR range and such was presumed affected, however the tank has been dry tested and has been in quite a few matches so the concerns are debunked.

There has, however been issues concerning turrent rotation.

1. The slip ring wiring must be done correctly and anchored to the turret ring (as you can see in the picture), or else the slip ring won't be allowed to rotate properly and tangled causing the turrent rotation unit and motor to blow (cost me a tk22 board). I've countered this problem by getting the generic tamiya 4WD motor, dismantling it and greasing it up and gluing the clutch in the HL turret rotation unit.

2. Due to the slip ring being placed in the central axis of the turret, The barrel assembly may not have enough room to elevate or depress, and causing problems like in point 1.

Other than that, the slip ring has proven very useful and I don't have to worry about making too many turret rotations, however caution has to be placed on making sure the turret doesn't jam.
