Many pilots look down on designing and flying planes with EDF's. Answers range from too short a time element of flying, spooling up problems, tight turns, etc., so many don't bother. I disagree and have designed a number of planes including rudderless and it always peak interest when I fly them at the club field.
For my favorite plane I built, it's called Magic. I started out using 5 bladed 64mm EDF's with 1300 mah Lipo 11 years ago and still use them by designing the plane light. Hardest plane to fly in wind and gusty conditions is the flying wing. So now add a 64 EDF to it and drop the endplates and add my "stabilizer" and this is what you got. Add some more design tricks(eliminate the reflex) and now you have :
1) a plane that can fly 10 plus minutes
2) don't have to worry about stalls
3) can fly slow or fast in a small field
4)can handle gusts and still do tight acrobatics
5)pilot skill is 3/5
Here's the prop version.
And the 10 plus min flight till battery dies. Time to re-evaluate what you think about EDF's.
