ENGINES-

GEAR 1: *VTOL Engine - High thrust - Pitch up [W]
Low thrust - Pitch down [S]

            *Z-Axis Thrust      - VTOL Slidebar  [Z]/[X]
              (FWD-BWRD)

            *Constant thrust - Provides a constant thrust i.e. you won't need to hold pitch up/down
                /thrust boost      
                          Input        - Trim UP

            *Hover                   - The engine power set as such it hovers for sometime
                          Input        - Trim Down

GEAR 4: *Main Engines - Do not exceed more than 30% unless really needed
Input - Throttle/Brake

MODES- Only turn one at a time for it to correctly apply

GEAR 8: *Normal mode - Normal

           *X-Axis Thrust      - While Holding Pitch        - Roll LEFT    [A]
             (LEFT-RIGHT)        (Up/Down [w]/[s])           - Roll RIGHT [D]

GEAR 7: *Realistic mode - Turns Realistically

           *Roll To Turn       - While Holding Pitch         - Roll LEFT    [A]
             (LEFT-RIGHT)       (Up/Down [w]/[s])            - Roll RIGHT [D]

GEAR 3: *Street mode - Hovers and goes forward

           *Forward      - Pitch Up   [W]

           *Left           - Yaw Left    [Q]
           *Right           - Yaw Right [E]

           *Pan Left          -Roll Left      [A]
           *Pan Right          -Roll Right   [D]

VISUALS- Mostly just for fun

GEAR 2: *Reaction Control System - Not fully for visuals but has a very minor effect seeing that
(RCN System) the craft have Gyroscopes

GEAR 6: *Parachutes - Again, not fully for visuals but has minor effect seeing the
weight of the craft

GEAR 5: *Cool LED Lights - Verified, this is only for visuals

*Note: It can also work without gyroscopes. Gyroscopes activates in Gear 8, 7, 4 and 3. So just disable them, enable gear 2 (For RCN System) and use Trim as Throttle. But its very confusing and hard to control (it can balance itself nicely tho).
