After flying turbines and all of their excess power compared to a DF I wonder if you'll be happy taking a step back on the power output and slower top speeds. The DS-94 is capable of producing high static thrust but I'm not sure about the TP velocity. I have gone the other direction by building and flying a turbine model. Now that BVM is stepping up to the plate and I think that large EDFs are viable. Until now if you wanted a standard size edf you pretty much had to come up with your own conversion. Your best bet for high performance is get the watts/LB in the 250+ range!
