To Group,
I will have to take the blame for this one and I am sorry for not having it the build manual. During the first flight of the prototype we noticed a heavy buffet in the tail plane when in high angle of attack situations. Like slow turns, say under 110knts. Or slow with no flaps. With out the gaps between the wings sealed there is a significant root wake formed. This will buffet the tail plane when the tail plane is down in the situations listed above. The wake is created thru the gaps and the spar and other attachments which cause very good turbulence. With the gap sealed, there is not buffet , i.e smooth airflow about the fuse and tail plane. I have been guilty of forgetting myself on a few occasions with the exact same results. No it is not fun and will give you quite a pucker factor….discontinue the flight as soon as possible if you have forgot and find out on the first flight! So, seal the wing root gaps!!!

Nick,
Will this happen even when the wing root is flared onto the fuselage?
