F-22 Help For EDF choise!!!

i am making 1/16 scale F-22 prior to making 1/8 scale just to make some flight test airfoils..etc im going to be using 2 midi fans from hobby- lobby and i dont know which engine should i choose - i was thinking geared_ Hacker B-40 L's ( ~ 500 Watts each) or speed 600 (12v. ~200 Watts) or maybe Jeti phasor 15/4. Batteries- thunder tiger 3 Li-Po 4200 mAh. Controller is going to be from hacker master's series with BEC, 40-60 Amp depends on motor. Please tell me any other alternatives on motors + controllers thanks Julius

that kind of helped - thanks another question how do i know what gearing do i put on motor for optimum performance like for hacker 50 's i think u can go all the way to 7:1 and Speed 600 has 3:1 which adds about 100 Watts compared to straight version

are you thinking fans or props? cause in fans you dont gear them. and jeti phasors wont go in a fan due to the fact that they are not kevlar wound, so they cant do the rpm needed.
