I don't know about the others here but I would not choose an LRP motor over a Novak, ultimately the Novaks have more options, there are something like 3 different rotors, 'L' and 'R' motors, etc. With brushless you need to be sure to use a brushless ESC, if you want differing winds with a brushless there are no x1 or x4 motors, you just have to tune the motor type and the rotor for more or less torque. Again this is where the Novak 'L' motor or a different rotor comes in.

Be sure it's a brushless ESC, I don't know if the LRP A.I. no limit is a brushless...

As for turns, don't overdo it, it's about RPM and unless you are going for ultimate speed or super acceleration you really only need about 40,000 or 50,000 tops. Many people go out there and buy the lowest turn / highest KV motor right off the bat thinking its the best, but then realise they have to gear it real low or it overheats, for an ST you really want ~6.5 turns tops and no less.
