I've never bothered to do much more then run up a gasser to temp then tuned and fly. I do run a new gasser on the rich side but that's about it. After a flight or two I lean them out. Another good test bed for the 20 is a Pulse from Horizon but any 1.20 size of plane and a number of the bigger 60s will work. You can go into the gas engine forum and read up on the DLE 20 and see what others are using for planes and break in.
