Now, I WAS using a 12.5mm high torque rotor on the Revtech. I haven't had a chance to test the motor with a different rotor to see a difference in braking power. I've also tried different sensor boards and several different stators to see if that was an issue. So far, it hasn't changed the feel. I will test a different rotor, however. Based on what some people said though, a larger rotor should, theoretically result in MORE braking power.

With regard to motor timing, I am using almost full timing on both motors (two ticks from full timing). Again, I haven't tried lesser timing. I'm racing in a blinky class, so low timing doesn't really help much.

Could there possibly be a software issue with Revtech motors and Hobbywing ESCs? My brother's 17.5 sedan has a Hobbywing 1s v2.1 ESC and a Revtech with 12.5mm HT rotor and his brakes are just as weak as my v3 ESC. Again, we never run our motors past 140f, which is WELL below the thermal limit for those motors.

Both of our cars are running the stock caps supplied with the ESC. We are both using high quality batteries, so I know that isn't an issue. Both of us are using an Airtronics MT4 radio and the RX-461 receiver. The only difference between our two cars is that he has a v2.1 ESC and I'm using a v3 ESC.

I don't know what hrs and shr stand for.

Still odd that changing motors would make it go away, don't you think? If it were purely an Airtronics/Hobbywing issue, it should happen all the time with any motor right?

You should not run HRS, SHR modes with most esc's on the market. I'm fairly certain that with the M12 you can run normal mode for throttle with a higher response mode for a suitable steering servo.

I'm using the M12 & have come from a Tekin rs pro, (don't use windows) and am using a revtech. I hope the brakes are every bit as good on the V3.1 as they where on my Tekin. I do run boosted so am keen on the results of this new esc.

All of a sudden my Xtreme stock will not start the motor. I have to spin it to get it started. Did cross check with a different motor and same result. Any ideas? Is my ESC damaged?

Spot on agree +1 only normal mode should be run thats why i asked if it was sanwa radio gear.

Does it work without the sensor cable? If so you have damaged the control card esc which runs the sensor module if it still doesnt work then one of the phases is damaged.

Esc needs repair must be sent back to were you purchased it from.

Yes it will run without the sensor cable. (sigh) Thanks!

Hey,
Im after settings and gearing for a reedy 4.5 turn and v3 speedy. First time trying mod, just wanna have a play :sneaky:

It seems your from victoria the best person that can help you is justin vergunst hobbywing factory driver he runs mod .

So your control card is damaged that runs the sensor port.Reverse polarity of the battery can cause it.
