I have a Great Planes PT60 that I have been flying for about 3 1/2 years now and it has held up great......over 400 flights. Great Planes kits are good kits to build, good instructions and good parts fit. There are many out there, but go with AT LEAST a 40 size. A 40 size or bigger will be stable in the air and you should be able to get your money's worth out of it. A 60 size doesn't cost much more to build.
