Most of the sites say just KX015074 for the combo with servos and gyro. Even Aligns site shows no letter. Most of the sites show the pro with a 3700kV motor and 13t pinion. Aligns site shows a 3500kV motor and a 13t pinion. I ordered a kit and got a "T" kit with a 3500kV motor and 14t pinion. The box and instructions both say these are the right parts.

Was there a problem with the 3700 motor and they have replaced it with the 3500 and 14t pinion?

What other changes are there?

Second thing is it looks like they want the ESC th be mounted under the battery and the battery connector to be coming out the top instead of under the front. Is this what anyone is doing or are people still mounting the ESC on the side and have the battery lead facing forward. Any pics of this and your wire routing would be great.

The kits with the 3500kv 450M are the newer kits. The 3700 450SP was replaced by the new outrunner motor. It runs cooler and isn't as hard on packs as the old motor.
