okay i have compared three motors for speed and tourqe and here is what i got

phast motor: not the speed of the the 4.2 but the tourqe of a 2.6

perfection 4.2 pro: best all around speed with not mutch tourqe

perfection 4.2: faster than phast motor but slower than 4.2 pro but more tourqe than the 4.2pro

and these were tested on a all stock microsizer 1 speed

Perfection says the 4.2 PRO is best suited for a 2 speed car, so maybe that's why it didn't perform very well... Just a thought.


silla

i took what you said and tryed out the whole thing over agian but i got still the same results

i like the 4.2 elvis in bits but the best all around motor is still the infamous pink clone motor that is worth about 40cents. nothing beats it in torque/speed

I don't understand your findings. The Perfection 4.2 Pro is advertised to have more torque than the Perfection 4.2. the reason it is reccomended for booster cars. In my experience the one 4.2 Pro I have has great torque, and probably more torque than the other 4.2s I have combined.

How did you come up with the findings?

My method of testing is unscientific, but the way I judge power is in my fet'd cars. I only half FET reverse, so I don't have as much of a problem with the front wheels being in the air when slamming from reverse to forwards, trying to back out of tight situations, hard to steer with your front wheels in the air. Anyways, (stay focused dave, stay on track, k sorry, I'm better now) with motors that have more torque, I can hardly tell the difference between forward and reverse, but with weaker motors, the difference is very noticable, and that is the case with the 4.2, where-as the pro is one of the ones that there is very little difference.

i riged an electronic scale to tell me how mutch tourqe its got and i got my budy down the street withone of those plolice spedometers to tell me how fast it was going

I take you you mean a Police Radar Gun...

Why dont you just make a mini dyno
