Wiring and... tricopter is the best for FPV, they say :)

 

And the wiring between transmitter and CC3D is as follow:

Some changes as last action of the winter holidays.

I'm just going to show the changes loading the images.

The top plate protects the electronics and serves as a battery mounting place.

The bottom plate protects the PDB in hard landing scenarios. The round tube is in place to avoid object etc to enter the body of the tricopter. It allows to see leds and to have separate screws for the protection and the PDB assembly.

A battery alarm has been added. 3M (r) dual lock has been used to make it solid to the tricopter body

Previous led solution was not making the rc model visible enough and too many leds were noit doing their job. This is just one instead, with a couple of resistors to lower the voltage to power the blue light. This is just a reference point and a display of the power being connected, LiPo on.

Legs now are all of the same length, so that when the flight control board starts and sets the levelling, it is properly horizontal.

Landing skids as you buy them: curlers !

To make lightweight landing skids for small multirotors I am using 1.50 euros hair curlers like these:

They are cheap. Good quality high density neoprene. Just remove the iron part from the inside.

What about leds on the motor mounts?

UAV OpenPilot configuration settings

This is the content of the file as I cannot attach it (save the content below in a .uav file and use it from the OpenPilot GCS):

Things to change discovered after being at the field for some tests:

1. The tail mechanism needs to be centered to have a rotation angle on the left as much wide as on the right
2. Remove leds on the legs. They are not visible. remove and place them elsewhere.
3. Change front legs to have same length as legs on the back.
4. Make covers for protecting the PDB (power distribution board: buy a 1mm thickness plexiglass) and the upper part over the FCB (flight control board). By now we have two holes for maintenance and configuration support that need to be closed.
5. Add the beeper for battery power control and discharge alarm, use 3M dual lock to fix it on top of the model.
6. A better way to fix the battery on the top of the model ?
7. Remember that you may land on wet grass and water may comes in. This is dangerous for the electronics.
