RE: US 60, rebuild and electrification.
Vmsguy:
I hadn't realized you were electrifying the US from Minn's US build thread. Your ideas about hatches are good. My Minishowtime uses the pin approach, with magnets holding down the rear of the front hatch.
How will you approach the cooling problem? With the tight cowl/spinner interface on the US, there cant't be much airflow through the firewall. Maybe some sort of louvre/scoop system on the sides/bottom of the cowling, with an exhaust hole cut in the bottom of the rear fuselage, or maybe in front of the wing?
