Isn't that BJ's Windstream with his own designed 6 cylinder boxer engine in it?
Yep it had a giant truck radiator hyd motor run fan, we removed 600+ pounds of BJ and replaced the fuel system control system and had an RR 250 c 20 ready for install. went from a cramped 4 place to a roomy 4+ cabin -
Fuel 70 gal under the floor
flight controls to tube as the FAA didn't like the Rotorway cables
Seats suspended from the roof
Where the radiator was is a EMS stretcher door
We wrer ready to install the engine when they ran out of money
They tried to lure investors with wine and song and not a flying example
We told them to get it flying first
Couldn't tell the 'bosses' anything
