Information on the D3 motor I found online suggested that the "Stock" or "zero" mark was 30 degrees mechanical advance.

Think i found the issue... WAY To much Drag Brake i had it set at 10% but i just got back from the track and id let off and it was like some one Threw a 1000lb Lead Brick down.. so I'm going to try to lower that. to 5 this is prob my Driving style causing this?

so on these new MMM motors, what endbell timing should it be on for boosted applications? (17.5) The new timings are 11-20deg right?

If you don't want to use the optional 21-30 timing...try max 20*. If you want to use our setting...we were set at 23* on the green timing board.

is it possible to order mmm motor with 20+ degree sensor? or i will have to buy 20+ sensor separately?

I had a MMM motor 17.5T
I put the sensor on min (10°).
Run boosted class.
With same gearing and ESC settings of my comp v3 motor.
it gets way to hot after 2 min 80 deg
I run in belgium on large nitro tracks.
changed the esc (gt2 pro) settings way down.
It had nice speed out of the corner but lackt top speed.
After 2 min the temp was 36°
after 3min 45°
Then 2 rounds later (40 sec) without fading motor stopt and started smokking like hell and the temp was 120°.
So after 10 min run the motor was dead.

Did you change your gearing from a V3 if you ran one?

These motors are a torque based design now so gearing change from a V3 is a MUST.

Sorry, +20* sensor is optional....MMM came with +10* sensor standard (11* to 20*).

for new mmm motor should i gear it higher or lower? roughly by how much?

Most motors when running with timing should not have mechanical timing added. If the MMM is a torque based motor like the LRP X12 then run standard timing on the motor. so with a +10 sensor board standard in the MMM i would turn it down to -10. For gearing, a torque based motor can take more gear try around 6.0 +/- .5. ESC timing, be easy at first, add a little a time until the motor temp rises or you have sufficient speed.
