I tried to remove old bearings from the 8.5 murfdogg I got. After installation I might have damaged the sensor board. The ESC reads sensor fault. Works fine in sensorless mode though.

Does Matt sell spare sensors? Will a reedy sensor work?

Also the bearings were really tight compared to other motors I have serviced. Is it by design, almost had to hammer the new bearings in the front side.

Yes, you can get spare sensor boards from Matt.

Also what is the correct way to get a used bearing out of the sensor board?

*I believe Matt, just returned and is working to catchup.
*He does have individual sensors for the motors.
*After speaking to him about changing bearings in sensor, he advised pressing them out, but is a tedious process to not damage the sensor. I use a bearing press-puller for the can. He also has ceramic bearings, which have been helpfull in providing even more performance. Hope this is helpfull.

Sorry for the lack of presence lately here guys... I have spent 4 of the last 7 weeks on the road, and then sprinkle in new years and XMas and I have had very little time to check in on everyone. Thans to my team drivers for keeping everyone going!

If I am not answering PM's on here, please shoot me an email as I check that daily most times.

Out of the 7 message boards I am on, sometimes one slips through the cracks.

Thanks to all of you for supporting MurfDogg Products!

Mine have all tested between 2200-2500kv at 0deg endbell timing. This just gives you an idea of what gearing to start with though. Not the true power of the motor. This also changes with the amount of endbell timing.

Speaking of Stock 17.5 motors, I searched this thread and couldn't find the answers to these questions:

How does the MurfDogg 17.5 compare to the other manufacturer's?

I'm running a Fantom Apex 17.5 with the 12.5mm high torque rotor and it is doing better than most of the other motors at the track. A buddy told me that the Novaks are pretty torquey so I'm going to try their Premium 17.5.

I run stock truck and would love to have as much power as possible while staying within the rules.

Any help is greatly appreciated as I'm happy to try something.

I've tried Tekin, no torque; Orion VST, no torque, although the V3 and V2 are good; I borrowed a FTM built Novak and that was crazy, felt like a 10.5.

Yeah I don't understand all that stuff. I like our arrangement. You build it and I will run out front with it.

Most of the time when tell people I am only running a 5.5 2pole 540 motor in my SC 4w they look at me like I just farted or something. Then they asked me how come I can run that fast and not thermal. My standard response is "Murfdogg Baby!, Race one or Chase one."

Several of the motors you mentioned are good power plants. I have personnaly used all the ones you've mentioned and definitely preffer the Murfdogg Synergy Motor. It provides the best bottom end torque and top end RPM. Most satisfying power plant I have raced.
