it better be high.
OS Speed V-Spec - FreeRideFrosty - 01-26-2007
It says 40,000 right in the specs. It is a sick motor.... but dynos on these things are like dynos were on cars a few years ago before everything was standardized. Any manufacturer can make the numbers go in their favor. The only real way to check out a motor is run it, or see someone run it in person IMO.

So, where did ya smuggle these in from?
OS Speed V-Spec - FreeRideFrosty - 01-26-2007
That is just an amazing looking motor. I would be scared to run it for sure. Imagine how much damage could be done with one tuning error or freak runaway.
OS Speed V-Spec - DAVEC-NITRO-RS4 - 01-26-2007
Dan, I'm sure you could pick up one that looks that good but doesn't run, for a whole lot less. Then you could just pose with it and never have to worry about messing it up.

Brilliant!! Can I make nitro noises and have someone just pass my truggy over the wire for the transponders every now and then?? It will really save on fuel and broken parts!

You got it. Just spray matte black on whatever motor you got now and we'll stencil the red lettering and flags on there....

I think you just found a new option to talk to your future customers about. Not ONLY do you paint bodies, you do motors too!!
