A more precise tune in the fact that using bearings will eliminate much of the friction. So...when put on a dyno, the numbers that are produced by the motor are more "true" to the motor.

So....by eliminating as much friction as possible, we can tune the motors to be more effiecient, and get more precise numbers on what the the motor is producing.

That comment makes absolutely 0 sense. It takes ball bearings to make a tune precise? Uh oh, I think that all of the other motor tuners are now in trouble because their tuning methods are inaccurate.

If you are going to present such comments please make them credible.

Intelli,

Would you not agree that ball bearings:

1. Reduce friction on the motor?
2. Allow the motor to be more effiecient?
3. Allow the motor to "operate" in a more "true" fashion?

I think the answer is YES, so..with this in mind, if the motor has less friction, and is more effiecient and runs true, is it not possible to say that we could get MORE ACCURATE "true" numbers from the Dyno, thus allowing us to "tweak" the motor more precisely?

That is my point...so if I mis-communicated my thoughts, or they were mis-understood, I applogize.

URC

WTF is "more true?" That is amazingly ambiguous. Runs "more true" As opposed to what? All of those other "less true" motors out there?

Give me a break man.

I understand that you are trying to market a product which may or may not be any good but please try to keep the bs to a minimum. If this motor is so great, it will sell itself.

Isn't that what Lube is for??

Like I've said before if you have the numbers show em...

Mike,

When the product is ready for release, we will release our data on the motors.

So basically you don't have any data.

I will never buy a 280BB motor again. I bought one for my RS4 and it sucked. My first problem came when the brush cracked in half. since my LHS didn't sell replacement brushes I had to make my own from a standard 540 brush. then to top it off, one of the can magnets came unglued which made the motor and expensive paper weight. Then I got smart and bought a speed 300 which is half the price and found that the 280BB had no where near the speed that a speed 300 has.

while yes the brushes are replaceable on a 280BB, by the time they need replacement, you will need to true the commutator also. I have yet to see a com lathe small enough to work. so really your better off with the $15 disposable speed three hundy

That was your experience.

The comms of these motors are able to be cut as a FYI.

You most likely purchased a 7.2v 280bb

I am sure they are able to be cut but with which comm lathe? I don't know of any comerically available lathes for motors that small.

Send a message via AIM to hpidriver
You want the 6V version motor, not the 7.2-8.4v, like Intel said.
And the comm can be cut on a normal lathe, it fits on mine. Or you could do it another way, right Intel?

Lemar, hit me up on AIM if you're on.

Where can you get the 6volt version of the 280BB? Is it the same as the Baja? The Baja is 35mm, but the no-name 280BB I have found seem to be 41mm (the can in length). I dont have enough room for a 41mm in my m18's setup without raising the CG (not willing to do).

Im also interested in knowing which lathes can trues such small motors.
