I wasn't too sure if the parking brake would work where located so I took it apart and tested where the on/off positions in the valve were. I determined the valve couldn't move far enough to activate before hitting the firewall. Need to re-loate to the firewall instead of parallel with the floarboard. Worked on figiuring out how/where I'd place the gascolator. Took the wing off the rotisserrie and put the fuselage back on.
