The strakes were definitely forcing air outward along the wing -- the fences put a definite stop to this! Followed Mayday27's advise and did an inverted test -- all went well. With the CG back further, the launch was a breeze -- there was no initial dip -- she flew straight off with some torque roll. Inverted was also nice and controlled with just a touch of down elevator to stay level. Rolls are now truly axial. The speed envelope has definitely increased, or rather widened. At slower speeds, she no longer "twitches" -- and the tail does sit a bit. The control surfaces are much more effective at slower speeds now. I can maintain level flight at less than 1/4 throttle. She is even more twitchy at speed now. Also -- I need to find a happy medium for trim b/s if I trim for slow flight, she climbs at high speed, and vice versa. Thanks again guys! It feels like a newer, MUCH lighter plane! Man, I love this hobby - the learning never ends!
AWESOME! I'm glad it worked out. I love my Mini FJ I can't wait to finish my version 2...SOON after I finish my Kronik2010 bird.

Happy flying,
