NEW FOR 2017 - MC2!

MOTIV M-Code motors, now MC2 for 2017, come pre-set to perform well in most applications. Each MOTIV M-Code motor comes with a specification check list specific to that individual motor. All MOTIV M-Code spec motors come standard with the new "S-HIGH" rotor. If you prefer a different rotor, please send an email via the "Contact Us" page on the Motiv site and reference your order.

Motiv dealers in the U.S. that have received MC2s are:

ProLevel RC
Fordham Hobbies
Lefthander RC
TQ RC Racing
Activ RC
Gripworks RC
Stormer Hobbies
AMain Hobbies
NorCal Hobbies

& More - Check your local hobby shop!

“Defy” Series Pro Li-Po battery weights

“Shorty” 2 Cell, 7.4v, 5000mah, 65c+ - 215 grams

ran my 13.5 in my 4wd buggy (B64d). ran 26/78 with the factory timing setting (small, indoor track). buggy was very fast! with a fan it came off at 150 after first heat. took the timing down just a touch for main to account for the extra minute.

next time out i'll play with gearing. very happy with the motor!

a lot of home work went into this motor since the Snowbirds. Pass the word; it a keeper and hopefully the new KING OF THE HILL.

Used the Motiv MC2 in 13.5 1/12 this past weekend at MHIC, where I finished 5th overall. Track is 45x90ish, CRC black carpet. Settled on 43 degrees of timing and ~82.5mm mmpr with the S-High rotor. Motor seemed really strong with very good fade, so I will likely use this as my starting point for future races.

I was at 79.4mm rollout, 41* timing and the S-High rotor and was really happy in 13.5 12th with minimal fade.

In 17.5 TC, a lot of us moved to a 4.3 FDR and 51* of timing, as a potential alternative to the normal lower timing. Just be sure to utilize a fan in TC.

They have been replaced by the 6000 packs as far I know.

They are still available at some retailers.

Paul receives motors every week or 2. I think he is expecting to receive an order this week.

Nope, use the one that comes with it.

I got mine today (17.5). Can't wait to put it on my B6D!! I am not familiar with the rotor/stator/sensor and what the numbers are supposed to indicate, but I am just excited to try it out.

theoretically the closer A B and C are the more efficient the motor will be
