That British olive drab colour looks just about spot on too. As for removing that sticky stuff, I usually use WD40 though I would test with the plastic first - I personally have never had a problem using this but it's as well to be careful.
Regarding the HL TK6.0 polarity for ch.16, etc, perhaps this schematic can help, though I'm not sure the image size displays or expands properly (I'm not very well versed in uploading images here, I tend to click and hope for the best
)

Thanks, Doc!. Yes, I have that schematic, and all the others. The issue is one of terminology. IR hubs tend to have their own unique pathways, and terms. There's a useful site here:

Where it says 's' for signal on the diagram, there's no indication on the unit case. But 's' becomes 'Output' on the PCB itself, I discovered. I'm just highlighting a few niggles for future TK 6.1s users, with some answers for them.
But, it is irritating to have to graft a slimline three-pin (servo type) connector onto the one supplied with the MFU. That IR receiver JST would never fit.
I don't have a TK 6.0 to hand, but I imagine the receiver unit/cable bundled with the bag of cables, is the one for the TK 6.0.
It's a one bag-of- wires/cables-fits- all package. But it doesn't.
It's no big deal, really. Just frustrating.
Yes, I began this build back in 2017. I had it the testing stage two years ago, but was thwarted by the mildly oblate shape of two gears in the R/H gearbox, and the track sticking. Thereafter, I was lured away by other projects... a familiar story to many, I'm sure.
Yes the SCC15 Olive Drab (British armour 1944-45),is only made by MIG, I believe,and was a great find. It looks the part, and is a treat for the airbrush. It never gums it up.
I'm really glad you're active on the forum again, by the way.
I've had a few short restcures myself; but the lure of the build is a hard one to suppress.
