    Subject: Picture of fillet
    Jesse Thanks for posting the picture. Similar to mod I have in mind. What do you mean you never flew the original? I thought you made the modification after you started flying the aircraft? Julian told me his fillet improved the slow speed handeling. My KIS is very stable and controllable at stall+20 kts. At stall+10 kts the aircraft is a bit "wobbly", small pitch and roll distubances. Don't really need to correct the disturbances, and the aircraft is still responsive to contoll input. At stall speed there are noticable pitch buffeting, and if the stick is kept in the aft position, the aircraft will sharply drop a wing (feels like 90 deg), and I have never attempted to see what hapens after this if do not recover from the stall.

How it works compared to the orginal I don't know as I never flew the orginal. Jesse Wright

    Sounds like just about a perfect stall warning to me. I am not saying that a larger root fillet would not help reduce stall speed. It may. But a good prestall warning is a very important thing to have. If your aircraft is a tail dragger do you have fairings on the gear leg to fuselage junctions? I really like the look of the larger aft wing root fairing. Not really a big fan of the big fairing at the forward part of the wing root.

    Mark My KIS is a nose gear version. It could be that the tail dragger behave differently. I don't think an improved fuselage junction will lower the stall speed, but it will maybe improve the handeling at 10 kts above stall speed? I feel I always am a bit fast on the final approach, as I don't like to fly in the speed where the pre-stall warning wobbliness occurs. But, in ground effect/flare I don't experience the wobbling/unsteadyness. Last weekend I went to the Duxford airshow in the UK. All old airplanes with round fuselages have wing-fuselage fairings that start off with a short radius at the leading edge and ends with a quite large radius at the rear.
