Missing parts to finish the frame.

I finally ended up drawing the missing parts to finish the frame. The new parts can be seen in the figure above. The part referenced by the letter "a" will serve to make the landing gear. After considering several solutions to the landing gear, I came to the conclusion that for now it is better to opt for a rigid structure rather than a solution with moving parts. The part referenced by the letter "b" will serve to support the boards. I even thought about using plastic hex standoffs, but as the Seeeduino Mega board only has three holes it was not very stable. Finally, the part referenced by the letter "c" will serve to make a plastic tensor for the yellow kite line with the black nylon cable ties. This part will replace the current tensor since it uses a metal ring to tighten the kite line so it does not come off.

The frame building is almost done.

Figure 1

As can be checked through the picture, the frame is almost ready. The original draft was changed a bit very recently. In the figure 1, we can see that three of the four motors are already put in the right place. At the point where the motor was not placed you can see the motor mount (black piece with screws not screwed). In the union between the plastic parts that form the structure where the engine will be screwed is placed a square of rubber to prevent the motion of this structure. The union of the whole frame is made with black nylon cable ties and kite line.

Figure 2

The walls of the central box (Figure 2) are made with square mesh like the one used in balconies, terraces and garden fencing. The mesh is also attached to the carbon tubes with black nylon cable ties.

Figure 3

Figure 3 shows in more detail the central box where all the electronics will be put in. We can also see the speed controller already placed inside the center box and attached to the square mesh wall. The landing gear of the original project has also been modified as it was too complex. A new simpler version has been planned.
