> Thanks guys! I really just built this thing to test tires under load at very high speeds. (I have a problem with them exploding) It will measure power though. I’ll post up some video at some point. The brakes are robbed off a mountain bike, found out that some of them use a disc. Actuated with a pneumatic cylinder and a solenoid. Works just like a full scale Dynojet.

> Kinda hard to quantify, but I am fairly confident my car has been over 150. I believe it to be the fastest XO-1 on the planet.

> I really just built it for this particular car. My car is obscenely heavy, (over 20 pounds) so the rollers on this dyno would apply way too much load for a conventional RC car.

> The brake is pneumatic and is really just used to stop the rollers. (although I can apply additional load with it) My car weighs over twenty pounds…so I figured if I made the road weigh the same or slightly more and concentrated the weight as close to the o.d. as possible, that should be pretty close to the load the car sees accelerating. I’m no mathematician, but I’m REAL good at cypherin’. :dance: I don’t know if that’s the right thing to do or not but it made sense to me and seems to work great so far.
