Any estimate on when more of the super 7 12.5mm rotors will be in stock?

Is it worth getting this rotor for 1/12 or just still with 12.3mm sized ones?

Running on tight tracks here.

I have to say, for an old school vehicle I am using (Losi JRX-S Typer R), it handles extremely well.

Oh, I also tried out the 1 cell 17.5 I was having issues with, the track I was practicing at though is swinging double duty for the owners HVAC business so was not ideal, but the motor with same gearing that I had at the previous track and the new timing board, 20 degrees, came off ice cold. So glad that this appears to be fixed now.

Sorry for the double post, thought I was editing the last one.

how hot is your motor when you feel it fading?

temped at about 170

Anyone know what the stock rotor is in the 21.5 Competition V3.0 MMM?

What Rotors have you guys tried 21.5 MMM

Thanks for the info and advice

From what Solara said, the 12.5mm Super 7 rotor appears to be the hot ticket in 21.5. I am assuming the stock rotor is 12.3mm .

wonder if the 12.5mm rotor is the hot ticket, maybe a version can be made that comes with it out of the box.

I got a question on reventon setup item, for max rpm like 150k 140k if I lower them down to 120k with everything else constant, my car will get slower at the end top speed right? I just trying to keep the temp lower by reducing max rpm without changing anything else

does this rotor work well with the 17.5 motors? in non-boosted t/c racing, we are looking for ANYTHING that will help give an edge...

I haven't tested any of mine in onroad, but using a 12.5 rotor with a MMM 17.5 or V3.0 1cell 17.5 and a 20 or 30deg timing board makes them bada$$. In 2wd buggy and SC I have never had an issue racing vs D3.5s, Sonics, or other motors.

They are just as fast if not faster than anything out there. Just find the sweet spot in gearing for your vehicle remembering that not all motors can be geared the same.

You are going to hurt your brain....can you simply tell us what you are running and I think we can all help you to pick the right board and setting for your motor...

Don't forget, you have to work with the gearing...and rollout.

It will have lower TURBO timing after the WOT. yes, it should lowered the temperature....also try go 1T smaller.

Right now...everything is OFF ROAD, on road is just....not there.

However, the last testing with the 21.5 MMM, the super 7 red rotor is just perfect, this was tested by G12314 for small indoor carpet on 21.5 MMM

Setup:
FDR was 3.85
Yellow timing board on pin 3. (that is = 32*)
12.5 Silver/Red rotor.

I think the same can apply to 17.5...probably go to 4 ~ 4.2 final, Green board full right (30*). But we have not tried that yet.....or at least I don't have any solid test result of this.

SOLARA,
Send me new rotor and a new green board, and I will test it Sunday at NOR-CAL, home of the REEDY RACE!

Solara: any estimate on when the 12.5 Super 7 rotors will be in stock? Will you make a version of the MMM with the 12.5 motor out of the box?

I have been all over the map with Blinky 21.5 for USGT. The setup Solara posted here has worked very well for me and matches my driving style. 6 minute race will have motor temps at 150F (w\ fan) and the 8 minute mains I see 160F. Both cases I experience no motor fade and have equal or better pace against the current crop of other 21.5 motors.

Also, watch your Brake & Drag brake settings. With the 12.5mm rotor, you should be able to turn these settings down compared to the stock rotor. This also helps to keep the motor heat lower.

For 17.5, I think I like the 12.3mm silver/purple rotor better in the MMM. For our carpet track, this rotor with an FDR of 4.5 and yellow timing board set to the middle has worked very well.

thanks jimmy, I appreciate it......
