How many bands on the Avistar. My short lived plane had 8. I would go into a gentle turn and all of a sudden it would pull super hard and I'd have to shove the stick forward. In the end I had the DR set so the elivator only moved about 1/8 inch up and down and it still did it. Is this because the front of the wing lifted up? My son nick named it the Crazy-8 plane.
Sure sounds familiar.. Unless it was a gust or radio hit, that kind of sudden pull up was probably the LE coming up. The number of bands is kindof misleading because there is a huge (in my experience) variation in the tension of #64 bands even brand new. And when you start reusing them it gets even worse. I probably use 20 now, of mixed age/tension, but more importantly I hold down the fuse and try to lift the LE of the wing up with 10-15 lbs of force, about 2-3x weight, and it better not come up more than a tiny bit.

if you put dowels going into the bulkhead from the wing to keep the le down, you may as well put on bolts because they look so much better
You are probably right.. I just didn't want to have to do that much work (reinforcing TE where bolts go through, doublers in fuse, etc).
