Been building a Bertella plans SU27 which was designed for two .91 DF's. It's 108" long, about 67" wing span. All balsa /ply construction. I was going to power with a couple of JPX 260's I have, but too much weight I think for this construction. Are there EDF's that would handle this size plane? What do these large EDF motor/fan rigs cost? I've got one Rossi 81/Turbax combo, but I'm not crazy about glo DF, especially 2 of 'em side by side. Any thoughts? Bill S.
