Well, the 1527 is rated for right at 3hp cont, and 6 hp bursts. The common motor choice for the baja seems to be the 2215. It is rated at 3.3hp, but will have more torque than the 1527 due to the larger diameter rotor. Pretty close looking at the numbers, except the 200 dollar price difference (if both were purchased new).

Thinking about everything... If a 2215 2y on 8s (22k rpm) with a 16t pinion works well, a 1527 2y on 12s (28k rpm) with a 12t pinion should do fine. The higher motor speeds and lower gearing should make up for the drop in torque. Speed control choice may be limited a bit, but a CC hv110 is capable of around 5000 watt bursts so that should do it. Decent lipos would be a must, 5000mah 30c cells would do. One might get away with a pair of the zippy 5000 30c 6s packs, less than 250 for the lipos there.

So... 300 for the motor, 250 for the lipos, and 250 for the hv110 you would have the makings of a decent setup. Still 800 bucks worth of parts... Not sure if HC has any giant outrunners that would work... I will let you have a look and report back!

After doing all of that math and comparison, I can't help but think my dual 1521 setup may be a bit overpowered. I guess it will run cool, and hopefully the turnigy hv plane escs will be able to handle the load. I figured that one of them would not be enough, and considering the price of 2 was similar to the price of 1 hv110 I though it would be ok. Main reasoning was based on the fact I had the motors, and could not justify dropping 500 bucks for the 2215 when the complete baja cost me around 300 bucks. That and dual motor stuff always looks cool! Now that I have a 1527 2y I guess I could change my plans, but that motor is earmarked for the big savage...
