All I can say is if there are people spending 300 or more hours an an AW 29% I want to know what they are doing. I have built 8 AW Edges from the 25% to the 40% and everything in between. If I end up with 100 hours in one I've been fluffing off. There really isn't that much to do. I vaccum bag all the foam so I can bag a wing tonight and then bag another in the morning and so on and so on. If you don't bag and have a couple of benches you can sheet several things at once. By morning they are all done. The fuse takes less than 1 day to build including the gear plate mods. The 25% and the 29% have no engine box, the firewall mounts to the fuse sides. I guess my point is I don't understand how guys are getting so much time in them. Just my 2c worth
