forgot the 2nd question. I would try a Playboy or something like it. easy to put together and a very good flying plane. your 4 stroker 52 wont be too strong or heavy for it. NO need to over build it either. nothing better than good old Mon-o-Coat. have fun building and flying. its still my favorite and prove at the field. have about 4 fellows, in the club building one. dick
