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

In tc it was 150/160 in 1/12 130/135. I'm sure results will vary.

I've been running my fan in front of the motor for a while now. When I switched I did not notice a significant different in temp either way but it does more the weight of the fan forward and more compact to the center of the car. Packaging it up there does get a little tight so be sure not to hamper the flow of the fan by having it jammed up against something too tight.

I have been running mine behind the motor, but I have quite a bit of space in front of the motor if I wanted to run a fan there. Balancing it out weight wise could help though. I just want to make sure there is enough flow and that it will cool the motor well. Thanks

I'm going to be running a Motiv 13.5 in a 4wd offroad class. I have the low/mid/high rotors and was wondering which would be best to use? I assume the high rotor...From my motor checker:

40* Timing for both
Mid Rotor
- KV = 3427
- RPM = 27762
- V = 8.1V
- I = 3.2A

High Rotor
- KV = 3113
- RPM = 25219
- V = 8.1V
- I = 3.4A

Which rotor would you recommend and where would I go with timing?

Per Paul, Mid or high rotor, 45deg timing on can. Fan on motor if possible.
