Probably a dumb question, but for you airplane experts, I understand the principle of lift, more distance over the top of the wing, reduced pressure vs. the bottom of the wing, hence lift. Watching some cool RC videos on Youtube, occurred to me when these jets fly inverted, the wing ratio is reversed, seemingly causing reduced pressure on the bottom of the wing. Why don't these planes dive immediately into the ground?
"AOA" or rather, angle of attack.
While a cambered airfoil will be sub optimal for the task, it will produce lift with enough negative relative angle.
From the drivers seat, you're just shoving a lot of stick into it while getting a head rush.
Next lesson .... knife edge flight
In this arrangement, you are entirely reliant on speed and thrust as the wing is at 90 degrees relative to the ground.
Here you essentially "floor it", stand on the rudder pedal and hold in just enough aileron to hold the 90 degree bank.
Fun with RC twins .... With todays brushless electric systems, it is easy to set up counter rotating propellers. this was not possible without a machine shop to fabricate a crankshaft in the days of glo power. Now we swap two wires around and get a reverse pitch prop.
these are bliss to fly, and my preferred arrangement for FPV.
It has it's own party tricks when married to our more advanced radios.
We can mix the throttles of each motor to our rudder so as to augment yaw control with active thrust.
by reducing throttle to about 30%, pulling full back on the stick to induce a stall, full rudder input will then produce a dramatic, violent spin that's fun for all ages
