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

What rotor comes in the motors stock? Are they all 12.5 rotors? Thanks

Yes, other than motors for classes that only allow 12.3 rotors, all motors come with a 12.5 rotor.

Put a 21.5 Motiv motor in my USGT car. Took it to practice on a carpet track with 80' straight and a pretty technical layout. Endbell timing 44* like it came. Gearing at 3.7. Motor was coming off track at 100 to 105 degrees after 6 minutes. Gear up to 3.6 and temp stayed the same. Is that normal for Motiv motors?

Hello. I would suggest turning the timing up 3-4 degrees and checking the temp and going from there. 3.6-3.7 should be right around where you need to be for gearing. The timing will probably increase as the timing is turned up. Try setting to 47 degrees to see how it runs for you.

Yea 44* sounds low. The gear sounds right, maybe actually a little overgeared. Timing should be around 49 or 50 really. I'd try timing in steps tho, don't just jump right to 49, start at 47 like Sam suggested and check temps.

Could someone tell me what size the flathead screws in the endbell are. Just went to adjust my timing and noticed the screw heads are messed up. Want to get new screws before i take them out.

I don't know the size but Paul sells them in a kit (link below). I'll try to get a measurement for you today though.

25.5, 17.5 and some modified winds should be instock towards the end of this week, with more spec winds coming in the following week. Look for the site to be updated and reflect this by the end of the week if everything works out.

Thanks!

Sam

How are your lap times?

I put the timing at 47*, gearing to 3.8. My fast lap times were within .4 seconds of the fast guys. I only got to run 2 1/2 heats, so not much track time. Thats good for me I am a b main driver.

Yes. The timing adjustment tends to be stiff.

Loosen/remove those three screws and then pop the timing endplate off a mm or two and rotate. Way easier.

I saw somewhere, maybe FB or something, that someone is making a tool to help adjust the timing. It's basically an open-end wrench that you can use to fine-tune the timing a little easier. Think it was 3D printed. Of course, I cannot find anything on it now.
