Are all 17.5 motors created equal?
I'm looking to get into touring car racing, in the 17.5T spec class. My question is, there are so many manufactures that make a 17.5T roar spec motor, are they all suppose to be the same in performance?
I've looked at a couple different 17.5T roar spec motors....
Revtech, 3000kv
Team Epic D3, 2300kv
Reedy Sonic, 2268 KV
Viper R/C "VST", 1900 kV
How can motors with different KV ratings all be considered equal?

I don't own a 17.5 motor but this summer it seems that all the faster guys locally were running either a Trinity Duo 3.5 or the Revtech 17.5 motors. If I were to go 17.5 I would get one of those and not look back.

With any motor just try to keep the temps down and you will be good. try to keep it around 140-160 degree F range. If you keep it there or lower all of the above will be fine. The motors I have seen go were all above those ranges typically by a fair amount.

Having just come back from the BRCA Clubman's meeting at Cotswold, I would have to say that there IS a difference between the motors.
Fastest cars I saw on the day were running Reedy Sonic, GM, Vampire and Revtech motors. My HPI Flux Pro-powered car didn't have the same edge, perhaps 0.5s a lap off - bear in mind this is a very big track, 60m straight, and three long flat-out stretches in total. On a smaller track, I doubt there is very much in it.

I have no information on the ultra sportsman series but can say that the 17.5 1 cell is awesome in my 12th scale car and the 17.5 MMM is almost unbelievable in my 22 buggy. I will be trying the 17.5 1 cell in the buggy after the IIC since the 13.5 1 cell (I have more than one so it was ok to try) accelerates faster than any motor I've seen and can still hang on the top end.
