No, the BL winds are in the can, which is kind of opposite of brushed motors. You can change the rotor and that changes the material, but the winds are in the can.

Well, you *could* put a bonded rotor into one of those motors but I really don't recommend it...

You will get less power with the bonded rotor...but you will also be giving up efficiency, durability, and longevity of the magnet.

I recommend simply getting the right motor for your application

Carl was right that the winds in the motor are in the can and those are what make the biggest differences.

Without knowing what kind of application you are intending your motor for I cannot really recommend a motor... for instance most off-road applications only require 5.5R, 6.5R, or 7.5Rs

Carl, oh yeah, 5 cell gearing... general rule of thumb is up another 2 teeth on the pinion... but that's for the low turn mod stuff... the 10.5 might require more gear....at least that's a starting point

So my question is can one change the rotor or something to tone down the horsepower? Will a 10.5 rotor work in a 3.5 can?


thanks

carl, I've heard that with brushed motors and 5cell you should gear 5 teeth higher... for what that's worth

Anyone can help??
With 5-cell Novak 4.5R (sintered) I drive a FDR of 6.6 at my Local Track.
Tomorrow I would like to test some runs with a 7x1 motor, any suggestions on a FDR for 5 cells??

Rob,

I haven't really played with a 4.5 with 5 cells...most of the 5 cell running I have been doing is with the 3.5

for instance...at tamiya with 6 cells we would run a gear ratio of 10.1:1... with 5 cells and the same motor guys are running around 9.0:1

Most of the time on our medium sized tracks I would say we gear a 4.5 with 6 cells around 9.2 ...so with 5cells I would make a guess that I would gear around 8.3 or so...

It's hard to say what to recommend when I don't know what proper gearing for you track with 6 cells is...

I know on some large tracks I have run as low as 8.0 w/ a 4.5R... and using that as a refference I'd probably gear around 7.2 there with a 4.5

I hope this helps?

Default GTX question

hi Steve,
do you know why my GTX buzzes when i switch it on?
there's a high pitch buzz.
i'm trying to set it up for the very 1st time.

i notice that the sound goes away when i adjust my futaba throttle ATV (e.g. increase from 50 to 75%).
i thought ATV is used mainly for adjusting throttle servo end-points.

i know with my GP cars, if i reduce the ATV, then i reduce or eliminate buzzing completely, from the digital servo.
but in this case, it seems to be the opposite, i need to increase the end-point to reduce the sound

thanks in advance.

wyl,

You need to set your endpoints to their maximum points before you do the one touch setup.

This allows the ESC to be as smooth as possible!

I think everyone is catching up on lost sleep from the race

I'm sure things will be back to normal around here soon enough

e/ Raises Hand

Why is this thread called "Ask Steve 'The Evicerator' Weiss"? Mr. Weiss is currently being called Scuba Steve. Shouldn't it be "Ask 'Scuba' Steve Weiss"?

At least we need some un-informed guesses where these nicknames came from. The stranger the better
