This photo, from Nov. 2012, shows that Bill has built his Coot in just over 3 years; - remarkable!
He used a Subaru EJ25 engine and a 3-blade Warp Drive prop; total empty weight = 1400 lbs.
Here, Bill is checking the EGT at home, easy to monitor with externalized exhaust stacks.
After building a trailer per plans, he took VH-WID to a grassy airport nearby,
where, after taxi-testing, he hopes to make his first flight soon.
