Some progress.
Motor mount completed with additional piece from this (based on the suggestions in mistercrash's thread):

Braking servo installed. Also connectors soldered on ESC and motor. I'm using CC 6.5 bullets on motor/ESC and Neu 6mm bullets on the ESC/batteries. I have some 2s batteries and a 4s that I'll be running in series to get 8s, so I wanted to change to bullets to make series connections easier. I still have to solder connectors to batteries. I'll also change my Muggy ESC to the 6mm connectors, since I use these batteries in it too.
