Bracket prep

There are three brackets in this build.

  • a small bracket that is bolted to the forward quad arm and holds the pitot tube.
  • a small bracket that holds the front of the flight controller,
  • a large bracket that holds the rear of the flight controller.

If you 3D printed the brackets...

...then you are done with this step. Ref: 3d prints

If you purchased the brackets...

the bracket center top hole on ONE small bracket needs to be drilled/opened-up from 3.6mm dia (.14") in order to fit the pitot tube which is 4mm dia (.16") per the image below. An 11/46" drill bit works.

If you are fabricating the brackets out of aluminum angle...

cut and drill 3 brackets per the dimensions in the images below.

  • Small bracket for pitot tube: only needs 6 holes: the 5 base holes plus the .16" dia hole.
  • Small bracket for flight controller front: only needs 2 holes: the 2 "top" holes.
  • Large bracket for flight controller rear: only needs 2 holes per the sketch.
