RE: poor traction issue, suggestions please!
WOW DB that is more like a snow jetski throwing up rooster tails like that, the reason the tracks on that are better is because they are mesh like hollow tracks so they allow small pockets of snow through to aid grip. Tank tracks are pretty much solid so they sit on the snow to spread the weight, hence you get grip problems, especially if your tracks have pad's on them it makes it even worse. Drill holes in the pads to let the snow etc throgh like the kyosho ones and it might improve it but you will not have realistic tank tracks anymore your choice. You must also realise these are 1/16 scale, so something that is say 15mm deep is about 2feet deep in scale terms, like someone has already said everything has it's limits, especially SCALED UP to real world terms...........Still enjoy the snow while you can.
Here in England snow brings everything to a stop with grip problems, so youre not alone me old son.........
