In conclusion, for Tamiya rc tanks a gearbox brace, a metal elevation arm and depending on which Tamiya rc tank your building and improved idler adjuster system are the basics for dialing in some reliability. Installing larger motors increases the ability of the model to run better in the backyard or survive longer in rc tank club battle games.
Enjoy whatever you choose to do, from basher, to IR fighter to shelf queen! It just doesn't have to be only one type of model, now does it, of course not!
