Hey, Great looking Plane~! I'm about to do the same and hope your learning curve can help me. First, how did you shorten the engine box to accomodate the extra length of the engine?? Second, were you able to achieve CG by moving components around or did you have to add weight to the tail. If you just moved things around, what did you move and to where. Seeing your plane has really got me motivated. Thanks~!
