Does anyone know the difference between the 17.5 2270kv red can and the 17.5 2270kv silver can? Both motors have the exact same specs and solderin tabs.

It's not like the 1870kv 1cell 17.5 red cans. As far as I can tell, they're the same motor, just red vs silver?

Good question. Thought at first you were talking about the 3s-4s version, never saw the other red one before. I think you are right about just the color being different. The given specs look the same.

Yep, Just a change in colour, the red looks better in my opinion.

Cheers

Hobby King would have to submit the motor to ROAR and prove they have inventory in the US. Their business model makes the 2nd part difficult.

Hopefully Hobby King will start stocking the motor in US inventory, once they realise just how popular the motors are.
And then, as HK done with their batteries, submit them to ROAR for approval.

Cheers

When you guys temp these motors, are you temping the outside? Or the gaps where you can temp inside the motor?

I noticed mine is coming off the track at 145f on the outside, but sometimes I've seen 180f on the inside. I figure the outside is usually what matters, since that's where I temp all of my other motors.

Temp the hottest bit you can find, the cool parts don't burn...

This is actually a good question, when a motor manufacturer recommends under 165 (or 74C for those of you who swing that way) does that mean the outer surface or the hottest bit you can find? I really don't know, because if it's the hottest part, my old LRP 17.5 gets to 180+ every run and is still ticking.

They do have them in US inventory. Whether they choose to submit (if comply with rules) or not is a question.

My LRP goes up above 200 every run and its still strong. Most who runs LRP pushes its limits without issues. LRP motors are of a different breed.. Don't know why...

I haven't read through the entire thread yet, but I'm looking to throw a 10.5 in my 2wd SC10, along with a new ESC.

Is there a combo on the hobbyking site that you guys could recommend for me? Does the motor have to be a "SCT" model? I only drive on indoor, high bite clay tracks. (OCRC and WCRC)

I'm going to go poke around this thread some more right now.

Thanks.

**crap, i just realize this is the onroad forum, sorry bout that fellas. im off to the offroad forum now.

Higher temp wire coating than others mainly. At least that lessens the wire insulation related heat failures.

Yes. But still doesn't explain why it needs to be at those temps to perform. My other motors does just as well way below those temps.

Any body know what size bearing goes in these motors? I have a 9.5 red can and the bearing on the sensor board end exploded after about 4 packs in one of my drift cars. I run the 17.5 in sct and the 21.5 in F1 without any issues.

The bearing on the sensor end is 3x7mm (not sure how thick). I bought a set from Duratrax (#DTXC1506) to have them as spares, but haven't needed to change one yet so I'm not 100% sure they will fit. Apparently the Dynamite motors, Trackstar (and maybe Reedys) all use the same sensor board/bearing holder design.
