Gene, watch the nose weight..I powered mine with a O.S. 60. FS and had to install the elev servo above the removable stab and add weight to balance it. Mine is the J.& J. kit(balsa) . The O.S. is a 2 stroke with a 744 stock muffler and they are heavy. The fiberglass kits of that era tend to be tail heavy so yours wont be as bad as mine.Mine is over 8 lbs. but still flies a lot better than I can pilot her. Lands slow with nose high,drags the tail .... Light is best but dont worry too much if you get a little heavy. Post your opions of your first flights.. Jim
