Notes n stuff1!1

Made another contestant for a challenge cus im bored. I really enjoyed making this one and I learned a couple different things while making it :). I'm personally really proud of the cockpit, it is by far the best one that I have ever made! Not feeling to good about the codes n stuff like that but I tried my best and this'll probably be one of possible two other creations i'll make for this challenge, so I'm hoping that I can make each one unique and better than the last. Hope yall enjoy! :D

Instructions (Very important if you wanna fly this thing correctly)

VTOL Takeoff:
- 100% VTOL
- 100% Throttle
- Once airborne wait until you reach 200m and then 50% VTOL
- Wait until you reach ~200 Km/H and then 0% VTOL

Short Takeoff:
- 50% VTOL
- 100% Throttle
- Wait until you reach ~ 100 Km/H and then pull up
- Once airborne wait until you reach ~ 230 Km/H and then 0% VTOL

Normal Takeoff:
- -75% VTOL
-100% Throttle
- Wait until you reach ~ 280 Km/H
- Pull up lightly (I reccomend using trim)

VTOL Landing:
- 100% VTOL
- 75% Throttle
- Try to stay straight while descending
- Right before touchdown 100% Throttle
- On touchdown 0% Throttle

Normal Landing:
- -100% VTOL
- 15% Throttle
- Stay above 270 Km/H
- Try to touchdown at ~270 Km/H

Background

The TPC. Dynamics EVO-89X 'HoneyBee' Is an American experimental lightweight hydrogen engine powered VTOL, built in 2023 to demonstrate and test Pratt & Whitney's new Hydrogen Steam Injected Inter-cooled Turbine Engine (HySIITE). The aircraft has a total of 6 HySIITE engines (Two facing upwards to be used in VTOL made in the rear, and 4 rotating engines on the wing roots). The 'HoneyBee', once exiting the experimental stage, will be used as a general aviation aircraft and may have some other roles such as possible aerobatic appliances, and even military uses as a light fighter or reconnaissance aircraft. The 'HoneyBee' carries parachutes similar to the Cirrus Vison SF50 'Vision Jet' (one drag chute and three emergency parachutes) to ensure passenger safety in case of emergencies. The 'HoneyBee' is expected to exit the testing phase by late 2026 to early 2027 once further improvements are made on the avionics and the 'HYSIITE' engines.

Features:

The 'HoneyBee' makes use of 6 Pratt & Whitney 'HYSIITE' engines which work like any conventional turbofan but unlike turbofans, these engines suck up air into a reverse facing engine core that burns hydrogen to generate power and water vapor. The remaining water then cools the engine, capturing heat and evaporating into steam, which is then injected into the combustor reducing Nitrogen Oxide emissions whilst improving turbine performance. Each engine produces approximately 11,250 Newtons (~2,529 Lbf) of thrust each, pushing the 'HoneyBee' to a top speed of roughly 730 Km/H at sea level. The 'HoneyBee' is made of lightweight thermoplastic materials that can be melted down and recycled once an aircraft is out of service. This will reduce waste and production cost of this aircraft by a substantial amount. Because the 'HoneyBee' is a VTOL, it needs to use advanced avionics just to stay stable during flight which may be simplified in future variants.
