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

Following are some suggested starting points for the MC2 line of motors for each class (we will update/add to this as often as possible). One key piece to pay attention to when adjusting your motor is Amp Draw. Try to keep spec motors around 3.0.

I spent all weekend testing the 13.5 and 17.5 in 12th and the 17.5 in wgt-r. Ran them back to back with the TSR and they are excellent. Fast laps all were on par with the TSR and the fade seemed to be a little bit less. In 13.5 I actually got .1 faster hot lap than with the TSR so that is encouraging.

Big thanks to Paul for getting a good product that will allow us to compete!

Default GTR and Touring

What would be the best 17.5 motor combo for a GTR and then Touring?
Would you change rotors and or what?

The MC2 with the standard High rotor it comes with should work for both of those classes.

From what I understand after talking with Paul they are all coming with the High rotor. That is how I have been running my 12th motors and had the best luck with.

I got a 17.5 MC2 in and is very excited to try it. The motor comes with S high rotor so I'm not sure if it is too much for 17.5 touring car on large track. The Stack is 21mm long so I guess it is no longer a short stack design? But I did notice the plastic divider is no longer there and the coils are about the same length as the v1 M code. On paper the resistance is on average 1.6 milliohm lower than the v1 I got. I guess the new design allow for short wire to work with longer stack to get both torque and rpm up? The KV is higher than my old v1 and the no load amp draw is also lower than v1 under the same 45 degree timing setting using a motor checker. The can only mark up to 40 degree of timing now. Does this mean the motor do not like to go above 40 for the MC2?

I think the stacks are actually 19.3. If you look the end of the stack on both sides there's a little green epoxy to protect the wire making it a bit longer. I'm sure when ROAR and other sanctioning bodies do their qualification they remove this to make sure the min value has not been exceeded.

No he is correct. It is just below 21mm long with out the green hysol.

I noticed actually even the stack is longer, the over all length of the coil is much much shorter compared to my r1 v7. This is a very different design for sure. I think the new r1 v15 has a similar stator design look.

Im sure whatever the reason was, it was done in the interest of maximum performance. I wouldn't get too hung up on specific build points, and save judgement for when you actually get a chance to run one....

...whenever they are finally available to the public.
