Gene, on disc I have the Sun Fli 4 and the daddy Rabbit. I had plans printed and sent the DR plans to a friend and he built the plane first. He loked it so much he talked me into building one. Two or three years later I built mine, there was no reason for me to have another old pattern plane, I still have the Kaos in 60 and 120 size so my thinking was, if you have a Kaos you need nothing else!! Well, the DR is smaller but I think it tracks better then the Kaos, it's like it's on rails. I was talked into building it as close to the plans as I could but there really are better ways to set up a plane sense 1966, the wood rail motor mount is just too old school, I did it but I wouldn't do it again. Engines sticking up and looking at you is just wrong. If anyone wants to tell me how {I think I know} how to put these into my files I can just send them to you by computer. Very easy build, flys very fast but lands nice and slow. Standard every day old school pattern plane!! I'm going to fly it tomorrow!!
