Lets hear it for planes that are RTF!.
I don't consider myself very good with my hands, at least where carpentry is concerned. Covering is a whole other disaster story. I'm not even that good at putting ARFs together to tell the truth. I always seem to run into problems. I have a cramped workshop (which unfortunately doubles as a storage room) so builds frequently suffer hangar rash before they even leave the basement. I just hate building.
I also lack time. The busiest part of the year for me is in winter so I don't really have a building season, since I have so much else to do. Kits are very time consuming.
