i think one motor has about a 5 degree difference and another a little under 2. I’ve had 2 volta sensor boards go out but nothing for my newer, less used v21.

I’m in the market for a new 21.5 motor and there’s too many good motors to choose from. Also do I either go for something like a nick bell or rotor Ron built motor or just do it myself. I can do the timing myself, and non-magnetic hardware, it’s just shimming. That I don’t know how to do. The nick bell built v30 with ceramic bearings seems like a good deal.

I guess my last thing - anyone run these on their motor? Seems overkill but seems worth it, IF, they last a long time.

Those types of ceramic bearings will not hold up to the speed and stress of an RC motor. That's why you don't see anyone using them. I looked into it a while back.

As for which motor to get, It's a personal preference. They all do the same thing.

So, I saw this and started thinking how you can weaken a magnetic field when the motor isn't under too much of a load.

That is why you have several diameter rotors, the larger ones are for more torque and the smaller ones for more revs.

Yea, I see that. What I'm saying is, it would be nice to be able to control that magnetic strength while driving. Therefore, you will have the high magnetic strength when accelerating hard, then once up to speed, the magnetic strength goes down so you will have a higher RPM and to allow the motor to run cooler.

What you want is variable timing. Less timing on startup and more timing when at full throttle. Look up field weakening, this is what happens when we apply timing advance.

Is this ESC available?

Hobbywing XR10 Pro G3. Boost timiing can be activated by either throttle position, OR motor rpm.

It's available on most ESC's sold today and used all the time in modified racing. Almost all stock class racing outlaws this feature and requires "blinky" mode be used.

I knew they were adjustable, but I was not aware that they can be programed to automatically adjust while driving. They only race blinkies around here, so I never paid attention to all the ESC gadgets.

I looked at the r1 boost settings and damn, I’m kinda glad I’m just blinky. Boost min/max rpm, turbo, turbo slope, turbo delay, plus the actual timing settings for turbo and boost.

all that plus the regular radio and esc settings. Every throttle percentage has its own custom curve and timing :P

Boosted 12th scale was a ball to run back in the day. You didn't need the best motor or batteries, just figure out the correct gearing and timing boost rate.

Has any of you used the new REDS Racing VX4 motor? I'm reviewing a couple of them, right now. I have to say, they are very well made. Even the standard $100 motor came perfectly shimmed and timed. They only needed about a 1mm shim also. No loose windings either.

I finished my review on the REDS Racing 17.5 Standard Stock motor. I still have to run it on The Jerry and I still have the Factory select version to review and test.

I found a 10.5T going through some of the motors I had made in 2008 (found the date lol), PM me your address and I'll ship it out as a gift. Now the quality is not perfect since at the time my goal was to offer okish motors for a lower price. The actual motors that I did spend the money to have them made to my specs came with much higher quality bearings and Kevlar wrapped rotor, but I only had that done to the low turn motors (1.5T, 2T, 2.5T, 3T and 3.5T).
