REFLECTOR: VG for naca scoop.

[Jim & Sharon Beck]

Thanks for all your good information on the VGs placement and other good ideas. I've been working on shortening my takeoff roll on my 173 Elite RG with 200 hp Lyc and MT electric prop. 2 people & 40gal fuel take me about 2700 ft to break ground at our 4000 ft elevation here in the winter at 50 degree temps and fully loaded in the summer much longer. So far I've added the lower winglets and gained about 300 ft on takeoff roll and just put 6 pr of vg on the outboard main wings, about 1/2 of the full recommended set. Hope to test that when the wind quits blowing and then will possible ad the full set on the main wings. may skip the canard or just put a few on as I don't have trouble rotating, just getting the main wing to leave the ground. will try your suggestions on the oil cooler and also a naca for back seat ventilation that doesn't seem to have much air coming through.
Thanks again
Jim

  I found these photos that I took at Copperstate in 2003.  If we assume that they helped, you can scale the distance from the photo.
