Turbo
 

Some guy at The Shack told me that you can hook up a watch battery to an enginge and make it turbocharged. Just wondering if that was in the least bit possible.

You'd make it a little quicker, I guess; but I wouldn't call that turbocharging it by any means. I'm not sure watch batteries could handle the current being shot through the existing circuits anyway.

You can use a Mini-Z "turbo" (actually a set of better,external FETs) to boost motor power. They are relatively easy to install if you can solder, and also allow for the use of crazy motors, like the low-wind ones Mini-Z guys use.

which mini z turbo is it?

if its the same one I was looking at, I think it might be like the one here
