Default RE: 1/2A ducted fan???

i still say the smaller apc props cut down is WAY better than large plane props cut down. to thick hubs, to thick airfoils, to slow rpm, and not enough thrust to fly itself. take one of those props cut it down put on engine stand then run it how much air is it moving? about 4-5 ounces worth.

apc makes a 5.25x6.25 that when cut down and using two of them will less hub thickness than you larger props and give 3 times the thrust.
