Looking for a better option for a cooling on Motor for 1/10 scale bashing. - RC-Monster Forums

Desert Rc

So I am just about over the heat issues with Mamba. Anyone that has read my praise of Castle products will know that I am a diehard, I just have to find a motor that will maintain lower temps for longer runs.

I have noticed alot of new BL 1/10 motors hitting the market...mainly on places like Amain. I know a few of you guys are BL gurus and I would love some suggestions on a new motor to give a try. I have tried the VXL series and I am not impressed with the performance. I would like something comparable to like a 4600kv mamba motor.

Now that is the first motor I need to try. I also have one other application that needs power. I am build a Rock Racer out of a axial axles and tuber application. I would like the speed to be a bit faster then like a 27t. Where I get confused is the 4.5, 5.5, 8.5, ect ect. I know that the lower the number the faster supposedly but is there a industry standard for these motors that match to a particular kv rating per Number?? Like I thought the 17.5 was comparable to a stocker 27T brushed but some of the number comparisons I have read the last couple days are leading me to believe that the industry standard is a very loose system kinda like C ratings...cough cough....MaxAmps.

Anyway I am in the market for a couple good cool running BL motors. One for my blitz and the other a durable/torque/peppy happy bl motor forr my little rock crawler/racer.

Any feedback would be helpful. I am constantly learning in this hobby and this part of the 1/10 BL side has always had me wondering.

If Medusa motors were still easy to come by, I would suggest the 4800kv 36-50. Despite their size, they stay amazingly cool and tons of power. I couldn't believe the difference on my CRT.5 going from the 4600 Castle motor to the 3300 Medusa. Otherwise, a Neu 1506, 1509, or the equivalent 14xx series would be very good too, albeit more pricey. Either Neu or Medusa are just better motors, and an efficiency difference of just a few %'s can make a HUGE difference in heat.

I dearly miss Medusa as well. I run a 4800kv in my SC10 and it hauls. I just something good for my blitz. As far as the crawler I just want something cheap as its got to be just a fun to run every once in a while rig. What about the Orions?? Crap??

what happened to medusa? shoot it seemed only a few months back they were a big hit?

they just like UE? make a few runs of some bomb stuff then backoff?

There was a notice on their site that said they were going out of the RC business. Later, it was said that Neu was taking over their repairs, and might release some of the more popular wind motors. I guess we just have to wait and see...

Medusa left the RC market, Neu is taking over their repairs and I beleive possibly manufacturing. If you could find a decent used Medusa that would be a good choice, otherwise a Neu motor is your best bet.

The VXL motors are not bad and are far more tolerant than the Castle Creations 1/10th motors. I had no end of problems trying to get a MM4600 or MM5700 motor to run cool in a Traxxas Rustler, but the VXL geared a LOT harder with the same esc and battery ran significant cooler, and drew less amps.
