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
“Thin Shorty” 2 Cell, 7.4v, 3900mah, 65c+ - 159 grams
2 Cell, 7.4v, 5000mah, 60c+ - 258 grams
2 Cell, 7.4v, 6000mah, 90c+ - 311 grams

Hey Mike,

The stator is at the ROAR minimum so it is within spec.

Thanks!

I'm a newbie to motor timing and I just picked up a Motiv 17.5. I noticed the end bell was set to almost the max timing setting. The included build/setup sheet says it was at 49 degrees.

Does this mean I will not have any room to adjust to add?

Thank you in advance for your help

Hey rcfan3,

The timing can go past the 50 line, so there is still room. Mine at 53 on the motolyser is a little past that last line. 49 is a safe starting point for most applications.

This video explains a little bit about what goes into a Motiv motor.

I've been running my 17.5 m-code with h rotor for a couple of weeks now. Fantastic motor. Much smoother and easier to drive than my D4ss that I was previously using. Very broad power band....it pulls good everywhere. Now I know why m-code powered cars were faster than me at the end of the straight when I was running the D4ss.

Did y'all watch that video? I think Paul nailed it there.

In my big box-O-spec-motors I have three Motiv spec motors, three generations of Trinity/Revtech motors, ORCA motors, R1 motors, LRP motors, Reedy, and Tekin's represented. The Motiv motors are the only ones that are dead on when I check them and need no adjustment to run their best out of the box. I'm really impressed with how good the sensor boards are matched and how close the out of the box timing is set to perfection with these motors. Together these things mean that anyone can put a Motiv in and have confidence that that motor is truly race ready.

Don't bother with the fancy checking tools, dyno's, etc.. Just buy a Motiv, bolt it in and have fun.

I've run both the 21.5 and 13.5 Motiv motors & both were very fast. I haven't run an R1 before, but I ran the D4 1s plenty before switching to Motiv. I've never felt that any of my Motiv motors have been at a disadvantage to any other brand.

I never used a d4 1s but I have run r1. Power is very comparable between the two. R1 feels like it has more rpm power band and motiv feels more like amid power band. That being said the motiv is the smoothest motor I have run.
13.5 worked very well all season in stk 1/12
21.5 is perfect for f1. The smoothness of the motor adds loads of drivability to the car.

Bought a high strength rotor for my blinky 13.5t (touring), what type of gearing change should I start with going from the stock rotor?
