I built the companion Piper Cherokee kit. It was OK, but nothing to rave about. The interior is there, but very basic- just seats and a yoke and a sparse instrument panel, as I recall. It has an engine, but I had trouble fitting it in, so I just left it out. It's small which makes it tough to work on, but with a little patience you can end up with a very nice model. You'll need to put some weight in the nose, or you'll have a tail sitter. About a year or more ago there was a thread on here showing the Cherokee (I think) made by a young lady who did an excellent job, maybe it could be searched up.
