Question about motor turns and ECSs

[DieCastoms]

I know this is oversimplified way of stating this, but is it accurate:

MORE turns = LESS torque but MORE speed
Any ESC can run a motor with MORE turns

FEWER turns = MORE torque, but LESS speed
running fewer turns means a beefier ESC


Ok, this question is for an 11-y/o friend Noah and his short-course truck.

He has a "Torment" that appears to have the following specs (as copied from a Horizon Hobby catalog page:

Spektrum™ 2.4GHz radio system including the DX2E transmitter and SR200 receiver
Dynamite® 20T motor and 12T ESC
2WD transmission with slipper clutch

I bought myself a HonchoRTR, and am planning eventually to throw a higher-turn motor in it. I was considering giving my stock 27T from the Honcho to Noah to replace his 20t. I did some searching and find warnings not to use 'more than a 12t motor' on the 12t ESC. But that truck comes stock with a 20t motor?? I've seen other 'product specs' for the same ESC that say 'for 12t or more' ..... what the hell . . .

And while I am on the subject, the Axial AE-2 ESC that comes with the RTR Honcho says that it is good for '19t or greater' but again, doesn't say a range..

I think you are turned around. More torque comes from more turns like 55 turn (as an example).

More speed comes from less turns like a 12 turn.

The motor limit means that is the fastest motor you can put in the rig. So a 11 turn motor (or faster I.E. 10T, 9T, 8T, 7T, etc.) would burn up your esc, but something like a 12 turn, 13 turn, 14 turn, 20 turn, 27 turn, 35 turn, 85 turn, etc. would be ok.

And if you really want to know turn, is actually winds on the armature. Check out the electronics section. Lots of reading to do!

Thats just a quick and dirty explanation.

this is why I was double checking . . .

So if I was Noah's short-course truck to go faster, I want to get him say, 12t motor (since he has a 12t ESC) and if I want my Honcho to pull harder, I want a higher-turn motor, like a 35t, but it will be slower.. Is that right?

sorry for being such a newb, here..

[TURTLE]

That is correct.

But really just the tip of the ice berg.

Agree with turtle but will add not to forget about gearing. If your drop from a 20 to a 12 you will want to use a larger spur(the big one)gear or a smaller pinion gear(the one on the motor shaft).
