These things have dynos?
 

I was reading in a post someone saying, "I put this thing on the dyno and it pulled 2.4 KPH" or something..


....... DO THESE THINGS REALL HAVE DYNOS?!?! Jesus if they do Id be impressed. Its either this, or he put it on a treadmill or something.

ya i wanna know too:p

I said that. Tamiya makes a speed tester for some old bit like(but bigger) product. They cost 10 bucks at YLHS

do you have a picture or a link?

I remember reading a year or so ago about a dyno that you just plug the output shaft of the motor into it, and hook these gator clips up to the motor and it tells you the max RPM of the motor, plus how long it took to get there.

tamiya makes a speed checker but it's not very accurate I think they're for those mini 4wd things that run on the tracks

that's pretty cool:p
