Started building in the 30's when that was the only way to have an airplane. Just never got over the habit. Have to confess I assembled 1 ARF and an ARC. That's it. Never again. I sometimes design too. Mostly successful and occasionally a disaster. The quality of some kits is superb and some kits a disaster. Prefer to buiild from plans so I can assemble my own kit. Try to get everything together in the shop before starting on the plan built types. Problem is lack of hangar space and piloting skill. One of the reasons for plan building is a preferance for scale or semi scale. If it doesn't look like a real airplane, Ugly Sticks, most yard bird and park flyers leave me out.
