Bizarre Question

At this point, the flap was only blown by prop wash, I believe!

I presume the purpose of the rig was to confirm actual pitching moments, pre-first flight. I'll try to find out from somebody who knows later this week.

In the 1960s (I think) DeHC were interested in STOL. I think this was a non-flying testbed to examine deflected slipstream effects. Mounted on a frame to get the aircraft out of ground effects and with that grid painted on the fin it looks as if they were measuring downwash effects over the tailplane.

Here is the flying version.

LANDROGER yes..you mean the long legs hahah..I see...missed that

Up in the NW Territories there are some really beautiful lakes and down in MN also...not to mention those fiercesome Great Lakes of the Mid West or Lake Hood in AK.

This airplane is iconic. I would love to own one. I bet there are many memories of these in Canadas' history.

Then of course in winter the floats helped with the ice. A really wonderful machine.

Flaps blown by prop wash - I can recall the Breguet 940, 941 and 941S, the Ryan VZ-3 Vertiplane and the VZ-5 Fairchild Fledgling. Then the jet versions, the two Coanda machines, Boeing C-14 and Antonov An-72/74. Then there was the McDonnell Douglas YC-15 where the jet efflux blew over the flaps, leading eventually to the C-17.

Here is the French Breguet 941 with flaps fully extended into the slipstream and flying in a markedly nose-down attitude.
