Jim,
If you go to http://www.model-plans.co.uk this guy sells the plans so you could have another crack at making one.
For those into R/C, Rubber Power, Free Flight, Jetex etc this website is a gold mine. He sells what must be 1000’s of plans.
What a great site Martin! Other KK models I built were Gannet, Bf109, Javelin,Cub and Provost but the best balsa model I ever had was a Lancaster which must have been 1/48 scale but still had rubber powered engines. My uncle made it for me for Christmas 1945 and I think it was painted as S for Sugar, now at Hendon, as I remember it had an Indian’s head and bomb tally on the ff. However, as I was only 4 years old I’m afraid it didn’t last long!
