I have converted a number Byron jets to EDF. All using the Byron and building it stock. Only major mod I did is a battery tray for the flight batteries. No other mods. With the Byron fan I can build an F-16 for under 15 lbs. RTF. The stock fan on 12S using a Hacker A50-10L Turnado motor does 22500 RPM at 100 AMPS which is better than my OS 91 powered fan. I have converted the F-16, Mig 15, Top Gun F-15 and now working on Byron's BD-5J. I never owned a turbine so I can not compare. Just building it stock it will fly great as an EDF.
