Hey guys just ordered by b4.2/centro combo on amain. Great deal by the way... Anyways old my tlr 22 2.0 I had for a week. Do the tlr wheels fit the B4.2?

I assume everyone heard about the combo? $325+ shipping after $25off code, get both b4.2 and centroc4.2 as one. That's almost $100 cheaper than separately.

What pinion do i need for 17.5 blinky? Med indoor carpet track
