This weekend I got the motor mounted, filled the f/r diffs (7k/3k), trimmed the servo tray down and got everything ready for a quick trial.

The brand new MMM went up in smoke when running the wheels slowly holding the truck after about 30 seconds after calibrating. It was working okay and then just a pop burnt smell and then nothing. It took one of the HPI SF-1 servos out with it too (glad it was a cheapo servo and not the good one I have on order).

So to a back-up MM with 5S and CC-BEC, still using the 1512 and 12T gearing. Just been doing a little small driving around the house to check things out. The MM was getting a little warm on 5S so I need to pull a little fan out of the toolbox to cool things down.

Right off the bat I can see a few pretty weak areas. The hub carriers seem to be a little thin and the a-arms seem to be very soft and bendable - not sure if that will be a problem.

The servo saver is pretty flimsy, but I found a stornger plastic spring, so we'll see. The stock servos are pretty slow and not too powerful.

Still waiting for the battery tray - so cell just ziplocked in place to test out the truck. A few pics to follow.
