| Higher Turn Motor Vs Lower Turn Motor ?
I have been seeing alot of guys running 35T and lower Turn Motors, Why is that ? I was thinking its for wheel spin but not sure.Ive even seen a Mamba 5700 system in an AX10 ? ! Seems to me that it would take away the "Crawling" part with a faster motor.... |

Yes, as you lower the number of turns, you increase wheels speed and decrease torque. A good balance of both is helpful to have when crawling. Of course, you can go with a 7T puller and have tons of wheel speed and all of the torque you'll ever need!

Decrease torque per amp as the turns get lower, to be exact. Max torque of a motor doesn't change with wind, just the voltage that it occurs. So a 55t may need 5 amps to produce 100 ounce/inches of torque but the 35t would need 7 amps. Both can get the torque layed down. People use faster motors for wheelspin, and enough speed to bump objects. My current comp rig has 55t motors on 6s lipo. Same wheelspeed as 35t on 4s lipo. Very nice... |

Thats what I thought But Ive been into crawling about a week so ya never know until you ask lol . So what would be the best/least expensive ESC/Motor for my scale crawler ? I'm running a Traxxas xl-5 and Integy 55T right now and it seems to be just fine for fun and runtime......That 7T Puller seems a bit much for my rig and so does a high turn brushless system.

Run what you have for least expensive setup. If you want a bit more power get a 35t and gear the rig down some more. If you want more than that get a handwound.

Wow another bunch of setup's to choose and try,Much different than a Short Course Truck.... Thank you for taking the time to explain. I will surely look into a 35T at least,I wont be in any comps just out in the yard and in the house annoying the kids and the dog lol

speaking of turns. how does the bushed verus brushless compare up in turns. like a 55t is roughly a what in brushless. What does brushless do for me that nothing else can?

I am going to take a stab and guess that the equivalant to a 55t brushed would be around a 17.5t brushless.(please correct me anyone) and a brushless setup will offer little to no maintenance and depending on the kv rating will give you more power,torque and will be more effecient with runtime depending on the quality of your battery and gearing.I run short course truck and have only had a crawler for about a week so I am still learning how to go slower lol

A 17.5 is closer to a 35t motor in speed. Brushless has no maintenence, that is the huge plus. |

he's saying 17.5T BRUSHLESS is equivalent to a 35T BRUSHED motor speed wise.
