I went and got this combo today from a LHS. They matched the price Castle is selling it for on their website,which I thought was cool. I only had a few issues with installation. First I couldn't get the 14t pinion off the stock BLX motor. I have a pinion puller but I couldn't use it because of my HR channel motor mount. The grub scew stripped and it was just a nightmare. I finally got it off just as I remembered that I have a 14t pinion from my Typhon, lol. So I went and used that. Another issue was the sensor harness. It doesn't come installed on the MMX, which is just freaking stupid. There are no directions and no obvious place to plug the harness in. I finally googled up something to help me out and I got it on there. Once I has everything installed I took it out and forward and reverse were reversed. Since I am using it sensored I couldn't just swap motor wires. I had all the motor wires in the proper places, so I tried reversing the throttle in the transmitter. Bad idea. I went forward at half speed and when I hit the brakes I did front flip, lol. So I knew it had to be something else. Again I went to Google and saw there was a setting in the ESC to reverse the motor direction. I changed that and went back out to test. All was good.
Running the same 14t pinion I had on my stock BLX motor resulted in very difficult to control power. Based on the Bolospeed calculator, I should only be picking up 5 mph by going to a 2200 kv motor, but man it sure seemed like a lot more. Insane torque too. I had set the Castle Punch to 50% which is like a 4 or 5 on the BLX. Definitely not enough. The Proline Trenchers don't help either as they really balloon. I took it back inside and put a 13t pinion on it. Again, according to the Bolospeed calculator 13t and 2200Kv is basically identical to 2050 an 14t. I also set the punch to 60% which is like the BLX 3 or 4. This combo tamed it a bit, but it still it super wheelie happy.I am running 500k in the center diff too. The Castle motor is just super punchy. I am very happy with it so far. I ran a full 6s battery combo through it and the motor temp maxed at 177 according to the log. My handheld could only find a max of 161. The ESC was warm but not hot, yet the log showed a max temp of 228. I find that hard to believe as my handheld was showing 140. Max amp draw was 226.3 but I can't find it on the graph. The highest I can see is 190.4.
Anyway here are a few pictures:
