INTEGY DYNO
I just got a used one about 1 1/2 weeks ago and it works fine, it's not a Fantom. It works great for breaking in brushes and running my tire truer. I had no way of comparing the motors I had and it helped me find out what I had. I have been racing on & off for a long time, so I kind of know what to do to get a fast motor, but the dyno made my motors faster. The good thing with it compared to using a turbo 30 or LRP charger to just do amp draw is the com. condition feature, because you can have a motor that draws real good amps, but if the com condition # is real high the motor sucks.(I found that out this past weekend)
