also, if you go after market control board beware right now the IBU2U has an inirtia delay built in. You cant turn it off. Eventually they will likely create an option to turn it off but its not available right now. Makes the tank horrible to drive in my opinion amd impossible to use in an IR battle.
Rich brought up an often overlooked point about the Taigen gearbox drive output axles. They have to be fitted to HL M41 sprockets (and other HL sprockets). A easy way to do this is to install them, then run them while holding a “sanding implement” to the first ~2/3rds of the axle checking routinely the fit of the sprockets onto the axle shafts. It does not take long, is easy enough and will save a lot of grumbling.
I do it this EASY way now, after it was point out to me by Rich.
