rcken, after looking at your post, i checked on towers site and I did not know that there were 20cc engines for fixed wings. I know they have 20cc for helis which fits roughly in the 50 size class. So, I assume that the DLE 20cc will fit roughly in the 60-70 class?
The 20 cc is more of a replacement for 120 size planes, but it won't fit on all planes of that size. That's the biggest problem with the smaller gas engines, they can be a bit "clunky"and won't fit in all planes. Some slim fuselages, or small cowl areas, won't accommodate a gas engine.
