Thank you very much. The four cycle may have been a-bit of a challange to mount properly anyway. The .40 is brand new and it looks to be a fairly "hot" engine as it has three transfer ports - I can surely grow into it. I was recently done a very good customer service turn by the folks at Great Planes, so I guess I'll just break down and buy thier C.G. tool.

Keep the flaps? I'm really scared.

Again, thanks and happy holidays.

Bill
