Hi Rob, if my drawings are correct CofG is 130cm from leading edge of wing, thats the main wing not the cutout where the wing dowels are, Hi John no it wasn't me , i have had the airframe for about 7-8 years, it just got pushed further and further back in the loft, had a major sort out 3 weeks ago, i was like a kid in a sweet shop found alsorts of goodies that i had forgotten i had. i will try to put some photos up shortly.
I have sorted the front bulkhead and installed mountings for a Roto 25 petrol engine and built a new tailplane and elevators.
Steve.
