You are pretty limited as to engine placement with stock mount and Saito 82. if engine is at 5", it barely clears back part of mount (I had to cut ears off). and it almost hangs off front of mount. Use you battery to change CG around. 5"to 5.5" is a good starting place. It flies good anywhere in that range. Don't go to 6" unless you like tail first landings. You'll love it.

P.S. I'm a new 3d'er also and it is just plain fun to fly. Landings are so easy.
