| need help geting the right motor
so here it is I have BRXL ecs, 3 and 4s batteries to use. I briefly had my stock Axial 20 turn motor in there (till I smoked it) and the speed was crazy, back flips, front flips wahoo! So my question is What is a good motor that will give me some longevity and that kind of fun? It has to be a brushed motor (BRXL is brushed only). I have a Torque master 27t but looking for a bit more wheel speed. I love torque tho. I looked at Brood motors but that is a bit overwhelming.... Suggestions and comments are welcome. Thanks guys |

If you want a Holmes or Br00d, you can email them and state: What rig What batteries (chemistry & cell count) What ESC What you want to do with the rig (crawling, rock racer, etc.) Your budget What motor you currently have and what you like/dislike about it They can then make recommendations of what they have. |

Your fun and motor longevity are at odds with each other. The more power you push through it, the less motor life you will have with a brushed system. Keeping with a 27t motor is a good choice IMO. You can add 12 degrees of timing for a good speed boost, and 24 degrees if you go easy on the brakes and reverse. If you really want faster faster faster, a brushless solution would be a good long term investment.

For a crawler or trail basher you'll want a sensored system. Is is strictly a crawler or a trail basher as well? There are a few different options from 13.5-21.5T motors.

Well, bashing .....of course! I'll crawl some too but mostly bashing. That Ridgecrest is one tough rig. I drive it pretty hard and I have no complaints so far.

| Re: need help geting the right motor
For a crawler/basher a 13.5t would be my choice. If it was strictly a crawler then I'd say 17.5-18.5t. Tekin makes a 13.5 and a 17.5 and Novak has a 13.5,17.5,18.5 and 21.5. All of these can be had for under $100. The price goes up when you start looking at the Pro4 and Roc 412, they are about $135-150.

what I've read about brushless is that censored is what I want but they are more maintenance. I really like the Holmes but want more speed.

| Re: need help geting the right motor straight line only I assume. don't know what kind of speed I get but I have to reduce the steering a bunch and still seems like the Ridgecrest is allways on its roof like a turtle on it's back.

| Re: need help geting the right motor
A brushless motor is less maintenance than a brushes motor by far, not sure if there is much of a maintenance difference between sensored and sensorless. Anything faster than a 13.5t in a crawler is stupid. Not to mention you'll lose tons of torque.

| Crawler nut, i managed to snap my rear locker and a traxxas driveshaft pin through my mip shaft, stripped 2 spurs, and have snapped drive pins that engauge the hexes, my wraith has more power than any brushed motor could produce and crawls as good, if not better. Setup, Castle mamba Max Pro with a Tekin sc4x 7.5t on 3s, i've snapped my rear steer axle shafts.

Ive broke most if that with a brushed motor minus the universals, just broke the dog bones. Plus you're talking a 550 motor, not a 540. You can't compare the 2. Irs been said before and I'll say it again. If it was that great of a motor then more people would be choosing it over the Pro4.

The pro 4 is a 540 for one so that means smaller... And is a 4 pole. The 550 of the sc4x keeps up with te pro4. And the sc4x requires the same amount if power if not less, and runs cooler with the longer can.

| Re: need help geting the right motor
Yeah, smaller. Fits with no mods. And I have the Pro4 in a 9.5lb wraith. 3 straight hours of crawling and full speed runs. 0 heat issues. Yes the SC4X will work. Is it a better choice? No... I went through the same debate a month ago when choosing the motor for my Wraith. The SC4X just isn't the best choice. Will it work? Yes, but I'd get the Pro4 or the Roc 412412 any day of the week before I buy the SC4X for a crawler. Like I said before, if it was that great of a motor then why isn't everyone running it?

i run a MMP with a novack 18.5 brushless in my wraith, crawler mostly,with good wheel speed. for bashing a 13.5 will be loads of fun, i would stick with tekin or novack for the motors.DONT BUY NOVACK ESC 's. If bashing is your game, you will LOVE the power and torque! Might even want more kv's Have fun!

No fight here. Just trying to steer him in the direction and that motor isn't really it.
