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.

Just got home from the Prairie Knights Classic, I would like to say how incredible the 25.5 motor is. I was able to bring home the F1 A-Main win with a Motiv 25.5 when the others were running a 21.5. The 25.5 Motiv motor just rips!!! The funny thing was the rules allowed a 21.5 but myself and Brian Wynn took 1st and 2nd with 25.5's. Just wanted to tell everyone that the power out of this Motiv motor is INCREDIBLE!!!

I was thinking about puting the timing back to factory and gearing to a 4.0 and see how it runs.
USGT right? I would say 170 is pretty much the limit to avoid burning anything up. In 17.5 TC I try to stay 160 or under. Most of the time I end up around 140 just because the gearing feels better, laptimes are quicker and it fades less. But I'm also running on a relatively small track, 80x36. I ran USGT once at home and ended up around a 3.7 gear and around 47* timing. That was at Stock Wars and the layout was very open and flowing, so those settings should work as a starting point on a bigger track as well.

As always, anytime you try something new (especially if it's a big change) I would recommend running for 2-3 minutes in practice, check the temp and if it's within a normal range, continue the run to your full 5 or 6 minutes and check temp again.

I'm hoping they get restocked soon... Canadian Onroad Nationals is 2 weeks after the ROAR Nats and I was hoping to have a couple motors for that.

Thanks again for the info. Yes, this is for USGT. I will try your suggestions out next time I get some practice time in.

No problem! Just wanted to confirm also that you are using a fan. I think most of us on here just assume that everyone uses a fan, but that's not a safe assumption to make. I've been using the WTF fans this season but will soon swap those out for the Motiv/Gravity fan.

That goes for F1 as well, a lot of our team setups for F1 are developed using a fan on the motor. 1/12 classes are the only on-road classes where the team is consistent on not using a fan on the motor.

Yes, I have a heatsink with a fan mounted on it.

My opinion is loose the heatsink fan. mount the fan behind the motor blowing forward on the motor. the heat sink will trap more heat than help dissipate it. I ran one on some offroad stuff in SCT and found that out. also in A VTA car because it was quick and easy but locked in too much heat in the can.

Thanks for the heads up, but I have not noticed that. The main reason I use the heat sink is because I needed the weight on that side anyway, I did check temps before and after install and temps did drop with the heat sink. I also use di-electric grease on the heat sink to help with the heat transfer.

Jon, heed Robbie Dodge's advice for temps, etc at Access, we're 80x40, so it should be spot on. Plus, it's the advice of my hero RDodge.

Default 10.5 for oval

My club is going to be running 10.5 Cup and I was wondering if the motiv would be good in this class. What rotor would be best for 1s? Thanks

Oh I plan to Ian. Would you call the track free flowing though? Next time I am out I plan to put the timing back where it was and try his gearing set up.

I don't know much about our motor in oval racing, so I'll ask Paul & let you know what he says unless someone else can chime in before this evening. Are you racing on the old grey carpet or the new black carpet?

Sorry I didn't get back sooner, I messaged Paul this morning and he responded with the following,

"If this a blinky class he will want the mid or high rotor with 40 to 45 deg timing, gear accordingly as we do not know. if this is for boosted the 12.3mm rotor would likely work best but this is totally un tested to us."
