Finally got the kit built. It took a lot longer than I thought it would, but it was well worth it. The weather was really bad earlier today, but the driveway was just a tad damp, not wet, so I took it out for its first drive. Even putting around the drive way I can tell this is going to be one fun car. The Savox servo is a bit noisy, but it's FAST. The 5S and 6S Zippy LiPos fit just fine, but the battery wiring is a bit awkward. I might have to shorten the wires on the MMM a bit to keep them away from the spur gear. I did have to shorten the motor wires quite a bit, and I could stand to shorten the white wire a tad more.

The Grid RC mount is super trick. I highly recommend it to anyone looking for an aftermarket motor mount. There's tons of room between the motor and the chassis now.
