Keybindings:

1 - VTOL Mode vs. Flight Mode
2 - Engines (On/Off)
9 - Ladders

Notes:

Throttle - Propellor blade angle (smooth movement required) + torque.

Power saving mode up to 1 notch above 2/3 throttle (for flying only on solar power).
Linear torque up to full power above 1 notch above 2/3 throttle.

Best speed @3500m (full pwr: 210m/s, pwr saving: 108 m/s)

Update 20/3/2020:
-Torque coupled to throttle (removed unnecessary keybindings, so easier than ever to fly).
-default prop angle set to 1 degree (on idle gives a normal decent-rate of <5m/s, and smoothes hovering).
-2 more solar panels added.
