Default Brushless motors

Can I put a 4074 motor in my red cat racing volcano epx pro, if so is that the fastest red cat racing brushless motor there is?

I don't have a Volcano (HSP), but Ido have a Caldera 10E (BSD), and I think you'll run into the same problems I have. Looking at the Volcano chassis it looks like the regualr 3650 motor is already almost right up against the central aluminum chassic brace, so you're probably stuck with a 36mm-diameter can:


...and it looks like there's a plastic ridge/brace molded into chassis about 1cm behind the motor: which would limit you to 60mm long motors.

So, Idon't own one, but from the pictures Ithink you could fit a 3660 motor in there unmodified, or go as long at a 3674 if you're willing to Dremel some clearance out of the chassis. That's what I'm going to do with my Caldera.

not certain what you mean by a 4074 motor.
But using a motor of higher KV rating than the 3300kv novatech motor can get you higher speeds.
As will running a 3s lipo battery.

Could I put a traxxas stampede motor in my volcano epx pro? I'm kinda new to this.

That's the physical size of the motor: 40mm in diameter, 74mm long. The average "540-sized" motor is 3650 (which is what comes in the Volcano: 36mm diameter 50mm long). 4074's are typically found in 1/8th-scale RC's.

It depends on if you mean the brushed version (12-turn Titan motor) or the VXL brushed version. Either should fit: the Titan has a metal collar you may need to slide off for clearance, and the VXL Velineon brushless motor has a black plastic endcap you'd probably have to remove as well (it makes the end of the motor thicker, so it may hit the chassis).

A cheap upgrade for a noticable bump in speed would be something like this Tacon 4000kv: though it's a bit overspec for your speed control and may cause it to run hot. For that price you can afford to give it a try.

I had a vxl motor in a volcano i used to own. the vxl fits same as the stock motor.
the titan 12t brushed motor will fit if you take the metal sleeve(what thas the label on it) off.

Thanks everyone and how do you tell the wheel and tire size.

stock wheels are 2.8inch rims i think.
The hex is a 12mm (the back part of the wheel) and this is pretty standard. most 1/10 scale tires have a 12mm hex.

Many people use traxxas stampede tires (talons) or proline masher 2000's.

other than different tires, not much you can do.
some tires simply work better on certain surfaces.

you can stiffen the rear shocks with pre-load spacers. this will keep the weight from shifting to the rear as much...thus keeping the front tires having better contact with the ground.
