Real Prop Plane (VIDEO) (Simplified Construction)

Took a lot of tinkering to finally be able to replace flying blocks:

-No Flying Blocks
-No Aerodynamic Props Covering the Frame
-Crazy Power To Weight Ratio (can fly straight up in reverse) (can carry heavy items, though requires the addition of more wood blocks to mount stuff on)
-Torque on frame from Wheels and Props almost entirely negated
-Extra wings included (gives a smoother flight, but are not necessary)

Hope you like it!
I was trying to build a similar plane but for some reason my plane could not fly smoothly with even very huge main wings and 2 prop engines on each wings and still took a long time for taxing...What is the keep point behind your plane?
