Rodney,
These were installed on an XL?
>1. Stall speed decreased 4kts
I'd say I got a good solid 5 but it could have been 4.
>2. Cruise speed decreased 3kts
I couldn't measure the loss, so I WAGed a 1 knot loss, I had to lose some
right?
>3. Control at approach speeds improved.
Mine too
>4. Nose drops on landing more abruptly when the lift finally gives away.
Yep
>5. Lift on the canard was noticeably increased during cruise.
I didn't have any noticeable lift increase in cruise?
>6. Decrease in take-off roll was 7% above what I got with the trailing edge
>fences (from 15% up to 22% or thereabouts).
I'd say mine was reduced by as much as 15%, maybe more.
high fields all the time, I would add them back. I was/am still looking for
>the magical 200kt cruise speed
Ain't we all!
I wonder if you might have gotten the VG's on the
Canard, miss-located? Which would explain the speed loss in cruise and
the increased lift in cruise.
