Some practical stuff

Common eVTOL types:

Lift + cruise (probably easier)
- Electrical needs:
  - Design/source a controller that stops the props at a particular angle to minimize drag during horizontal flight
    - https://www.youtube.com/watch?v=Y_BasX4mq08&ab_channel=DrJamesE.Pickering
Tilt rotor (transition algorithm will be some work)
- Needs large props
- Needs solid servos for angling the motors forward

Things I recall from comp

VTOL motor power draw is high, especially under headwind

One solution is what Carleton did with its raised/triangle rear stabilizer on their craft, “Apogee“, decreasing wind effects and making the line centre of mass angled. The rear motor did not have to do as much.
- It looked similar to https://www.youtube.com/watch?v=hOFbiU-alnI&ab_channel=Viewpro
- Note that Carleton’s craft was really fragile compared to what they did with it. Don’t turn with too small a radius at high speed or the craft will be ripped apart in mid-air.
Side note: Guy from Lockheed mentioned that winged mode flight requires a forward center of mass to prevent pitching backwards

the horizontal motor draws a lot of power, and we can minimize its current draw and stress on the system by using a 12S.
- Seen as it wont stress the system as much, maybe step down from a single 12S (option 2 in diagram) is viable? Definitely need to look into this
6S are used with the vertical motors to save weight. They don’t need as high a power output and are mainly only needed during takeoff and landing
Some kind of encoder or hall effect sensor + controller (on or apart from the ESC) will set the position of the vertical motors when transitioning into cruise mode
I’m thinking two rudders on the square/triangle shaped tail of the craft.
- Not sure whether we need elevators on the tail because I don’t know how necessary pitch control is for a VTOL.
  - Maybe the rear 2 6S motors can provide needed pitch?
  - Maybe the rudders can be angled to somewhat control pitch?
Topologies that use 2 or 3 vertical motors instead of 4 are yet to be considered…
