Frame Research

Material

• Carbon fiber sheets are most common - light and durable

  • Conducts electricity so everything needs to be well insulated

  • Blocks signals so need to place antenna in a good location

• HDPE also an option but not as strong

Arms

• Easier to fix aircraft (and cheaper) if the arms are replaceable

• Having unibody (arms not removable) could be less machining

Shape

4 Arms

Dead Cat

• allows space for a camera at the front (and no rotors in the way)

True X

• Same stability on every access since the motors are all at the same distance

• More aerodynamic

H Shape

• Wider so it could fit the drone more easily

Stages

2 Stage:

• Can carry more stuff

• Could put a nice 3D print insert to enclose everything
