Trex 450pro problem or not?

I ordered a Trex 450pro combo from a common r/c helo web site and the sealed kit came with a BL450M 3500KV motor, not the 430SP Brushless motor(3700KV) that every web site including where I got it shows.

Also the sealed bag had a 14 tooth pinion.

My box and instructions both show the 3500kV motor and 14t pinion. All the web sites that have down loadable instructions show the 1700kV motor and 13t pinion. Has Align changed what the pro comes with?

OK, now I'm confused even more. There are KX015074A and T kits. Web sites show the T kit that I got with either the 3700kV motor or the 3500kV motor. All show a 13t pinion.

Assurance (alignrcusa.com), which is what the seal on my box says, does not have a T kit on their web site but the A kit they have shows the 3500kV motor in the pictures and says 3700kV and 13t in the text on their site.

Aligns site does not say A or T kit and shows the 3500kV in the pictures and says 3500kV in the text. They also still say 13t pinion in the text.



So has there been an issue with the 3700 motor and they replaced it with the 3500 and a bigger pinion???

Don't know about the pinion, but from what I understand the new pro kits are coming with the M motor. I hoped mine came with it, but it was the SP. I hear the M is the better choice. Cooler running and more power.

I hate hot running, power robbing stuff, so I just bought a Scorpion 2221-8. Efficient, cool, and powerful.
