Also, look at the prices... The 1512 is more expensive than the axi, as it the 1915 (by quite alot). And they are for different applications. Axi makes a great outrunner, and castle will have to step up to excede axi's standards.
We can all agree that neu motors are some of the best in the world, so they should perform well. If I was making anything to race i would go with an inrunner, for both construction and performance. If i was making a crawler I would go with an outrunner. As for a dual purpose vehicle, it all depends on the speed desired...
I have a 6x6 maxx based truck, and I run an axi 2826/10 in it. It is geared for about 20mph in 2nd and 8-10 in 1st. It has tonns of torque and can crawl with the best of them. It will also jump and has plenty of speed for bashing, plus it has exceptional throttle control (due to the multipole design and the great firmware on the MM).
As I said, it all depends. HP (watts) is not the be all and end all of rc. Just read a car mag and you will see that the shootouts are not always won by the big number car...

That's why I keep asking about torque :) That's why I keep talking about gearing down to the same shaft speed. Power and torque are directly related via rpm.
