Final Design for Main Frame Centre

Right after modelling the main parametrics of the frame, I’ve gone on to make it ready for 3D printing.

First, I have added screw holes in the bottom of the frame for attachment of a battery holder, and I slightly thickened the top of the walls on the long sides to allow room for embedded nuts for attachment of a lid.

Here’s the bottom:

8 screw holes on the bottom for attachment of a battery holder.

I may not use all 8 screws, but I have put all the holes there in case I do need to.

For the top I have modelled in four hexagonal cavities for nuts to be embedded in, as you can see in this section analysis:

Connecting the Electronics and Starting to Design the Casing

Ok – Christmas is over and I’m back to work. I’m leaving the program for now and moving on to the physical quadcopter: once I have a finished and connected product it will be significantly easier to complete the code and test it.

The first step is to work out everything that will need to go into the quadcopter. Here’s a shortlist:

  • The 4-motor ESC.¬†I’ve acquired a central speed controller that contains the circuitry for powering all four motors, negating the need to have a seperate ESC on each arm.
