Default Roar

Here is what I know,

Roar says you can not switch arms in cans or endbells. They are verry descriptive about the motors.

Roar says no epoxy balanced motors, and no quad magnet stock motors.

I bought some hand out motors that had a chrome can and an epoxy balanced arm. They were basicly monsters. REALLY fast, but not ROAR legal

Here is some discussion on it

Yeah, that is called a "Hybrid" motor, which is illegal. This has been gone over many times before.

They're out already (I have one).

More rpm and less torque than a regular MS. I have to gear it about 2-3 teeth smaller than my MS's.

Overall, I think that the outlaw version should be a better motor if your track allows them. Even more rpm, with about the same torque and no balance holes to reduce overall power (watts).

There are 3 different arms. Binary arm 36 laminations, ROAR Stock arm 38 laminations and Monster arm 40 laminations. The binary is too short (short stack wire lenght) and is epoxy balanced. The other two are long enough and drill balanced so they are both roar legal arms.

Default Ti coated armatures

Has anyone tried to titanium coat the arm of a stock motor. If the theory is correct the titanium coating will reduce friction on the bushes and will reduce the heat inside the can to give a much better power over the duration of the whole race.

The problem is the coating will add to the outer dimensions of the surfaces and the clearance between the shaft and bushings is already at a minimum.

I have seen some "Specially" tuned Arms that have the stack lamination polished. I am assuming this is to reduce windage in the can. Hummm......

Default I have thought of that

I thought that the arm could be trued to compensate for the addition of the coating of the bush could be enlarged. It could be dont but would it result in a benefit at all is the question. People always dicourage you with " That will only give you .01 of a second whats the point" But i say it's the .001 of a second that add up to the seconds.

Just a thought.

I know this is the stock thread but could not find the 19T one. Quick question.

What is a good brush and spring combo for the Chameleon Pro 2 19T Spec. Can anyone help?

Try Trinity 4499's or Reedy 767's with double Red's. I'm not EXACTLY sure what to go with for a Chameleon, but that should be somewhat close, and it will give you an idea of what to do.

If I understand your question right, you're talking about using titanium as the comm surface, instead of copper? If that's it, then I don't think that would do any good at all, what little improvement you might gain in wear(or even big gain), you'll more than lose in electrical resistance. Copper conducts electricity MUCH better than titanium does(pretty much only silver is better), so the the increase in resistance by using titanium would likely make the motor lose a BUNCH of power, far too much to be of any good. Having said that, I WOULD be interested to see if it were possible to have a SILVER plated comm, now THAT would have some intriguing posibilities....

Default You misunderstood me.

I am talking about the shaft that runs inside the bushess at the end of the can and end bell. The parts that all Roar stock 27t motors have instead of bearings. Coating the shaft that the pinion attaches to and runs through these bushes where the most amont of friction beside the brushes against the com which is required.

My Epic Roar Stock has 36 laminations.... This one had deep drill balance holes. Not sooo good as you can see....
