I always hesitate to jump in on these discussions of aerodynamics. I thought I knew a couple of things, but then Jerry Burr or Jim C. comes along and I have to learn it all over again.
Flap gap FLOW is a GOOD thing, and helps in the production of low-speed lift.
Flap gap seals CANNOT be considered a help in the flight regimes (slow) that we love our Cubs for. If they're designed to SEAL the gap, gap flow will be eliminated, NO?
Yet, I haven't seen Murph's seals, so what do I know?
There you go, Jerry. I have set up a target. Shoot that sucker full of holes.
Jerry, did you get that new false-spar wing in the air yet?
I've kindof stopped building 'til I hear how the thing performs.
Will you be flight testing it without the slat, as well?
Sorry, guys. Off topic, but maybe we can all learn something we thought we knew.
