Paul,
I don't claim to be a expert but I have done a lot of work with props on both the ECL and IC power. The main reason to use the "E" prop is load. The standard props are two to three times the blade thickness compared to the "E" blade (this is APC or other brands) and the hub is also much thicker. This is done to take the cyclic pounding of the IC engine. The thin "E" props use 30%+ less amps to turn the same rpm on our electric motors. That's a lot of extra battery you would need to haul around and likely would need a larger motor also, all adding more weight. The APC's are very hard to beat even the wood electric props don't match it's performance/amp draw. APC puts a lot of engineering into its props, that why cutting them down usually reduces the performance.  This has been my experience, others may see it differently.

Larry,
Who makes the Majic props? They don't come up in a goggle search, are they cottage industry? I agree there may be other props that are as good or even better than the APC's but they will be special not off the shelf. For off the shelf the thin APCE props are pretty good compared to any other off the shelf props electric or standard. Don't get me wrong, I'm not saying that other props are not an option just that of the normal available ones the thin APC's perform pretty darn good and have significantly less amp draw then standard props.

I noticed the other day that Aero Products carries them.

Props!!!   Now ask  Paul Waker He uses a carbon 3 blade  Majic prop.

Is that a tractor or pusher prop??

Looks like a tractor to me !

Looks to me like you just glued 3 APC 11 x 5,5 e-prop blades together and then painted them with carbon textured paint!

you mean this one? :- )))))

as far as I know they cost 40 EURO, not $  ... but I can say they last forever ... even on rocky bulgarian "grass" :-)))

Only after you've mastered the talent of always landing on the wheels, with the engine off.  I'm sad to say that I'm no there yet.

3 blade prop is a protector for your canopy and turtle decks from sanding off on concrete 

but this is electric column, so if you land unexpected, you have usually flame on instead of flame off, so broken prop is not the only damage in such case
