Recommended key bindings without keypad

While patiently waiting for ANY joystick to become available I´d like to use my wireless keyboard with integrated touchpad, so I can lean back and enjoy. (The wired kbd & mouse are a PITA.)

I want to fly GA, so I mostly need reassigned keypad keys (ailerons, elevator), flaps and brake.
For VR throttle F2 F3 are difficult to sense, so reassign desirable as well.

Instead of going thru all the key bindings in search for a good layout I thought I´d ask.

TIA
