I'm not complaining (the 1406 motors sound awesome and I already have a 1410 combo on order) but I'm curious why the change of heart regarding building a slotted motor in the 36MMX56MM size?

Is is just that we are wanting to run heavier cars with 36MM size motors?

Pretty much -- cars are getting heavier and heavier, so more torque is necessary to keep pushing 'em to higher and higher speeds and acceleration.

While slotless motors rev faster, have less inductance (so respond faster) 4 pole motors have much more torque -- and with some of the software changes we've made to run the big 4 pole motors well (like the 1515) the differences between the motor designs have become smaller.

Note that I was talking about "light" 1/10th scale vehicles in that post -- but the trend recently have been to heavier, more robust 1/10th scale cars.

Also -- please note that we haven't discontinued the CM36 motors -- they will still be available. So, what we recommend is that for lightweight 1/10th scale vehicles where maximum acceleration is the most important aspect, the CM36 slotless motors are still best. For heavier cars, the 1406 four pole motors will be superior.

Thanks!

Thank you, Patrick.

more awesome products.... like already said a sensored version of these babies would be the icing on the cake, and one below 2000kv would be the best brushless crawler motor ever.

Icing on the cake for us and an unfair advantage(the best kind!) over others who still think the green stuff is for bashing!

I remember this happening thick and heavy only a couple of years ago Brings a tear to my eye... how things have changed now

Isn't it great?! I felt like the proverbial fox in the henhouse the other night at the track. When my buddies at the pit table saw I had this "puny castle motor" in my rig and I was running an uncharictoristic 2s they all laghed and asked if max power had gone soft! After the first qual I was the one laughing when I was hit with a million questions about what they all thought was a cm-36 motor and how the he'll was it so fast and not melting a hole in my rig.

That'll teach em
Sounds like a great motor.

Thats a good story, they never knew what hit them

So what is the motor Watts rating? And is there a 5mm rotor option?

I would hate to see when you hit 85mph it will just be 2 flameing tracks and rc car will be gone.

Umm, that's 88 mph.

But thats only with the additional Flux Capacitor addition.

Awwwww crap I cant believe I put 85 I have only seen them about 50 times each .
