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
