Hi Barry. I just got the plane yesterday. I weighed all the parts, some hardware still in the bags and it comes out to 5.5 lbs. Now there are some things that won't go on so it will be a bit less. I figure about 8.5 with the YS 110. I have run into snag though. The screws for the control horns are too short for the surfaces which is no big deal. The other problem is the backing for the elevator control horns is only on the bottom of the elevator. I need to contact Maxair and see what to do. I guess I could do a bit of a build thread. I was thinking I would take pictures along the way and then do the whole thing at once. I will keep you posted.
Don
