Hi tech shock absorber legs for multicopters.

I made up these hi tech shock absorber legs for my grandsons quad we are building.  Considering the hours I often spend to find a better design for making copter legs that don't disintegrate on every hard landing, It took me about 10 min to stop laughing from the simplicity of the brilliance of this light bulb…

Nice video for those who want to start and don't know the basics !

Hi, I just watched this video, and it seems to me a good ground base for those who want to start with multicopters and don't know what's the best platform.

Prop Removal Tool

I seem to be removing my props often, and I worry that my hand holding the motor while I torque the collett on or off is not strong enough and I certainly don't want to use a steel tool like a Channel Lock.  So, I use a small plumbers strap wrench, pictured below.

This one is overkill because it is made for, well,…

Inexpensive cover for my APM stack

I accidentally discovered a perfectly fitting cover for my APM stack:

Yup - a cold-cuts box.

I am using a set of thumbscrews to hold my stack to the hexacopter frame , and the cold cuts plastic box fits over the thumbscrews perfectly.  The cover doesn't budge in a hard landing or while…

Steps toward ESC feedback using SimonK

Most of the pro multicopter set-ups have feedback from the ESCs so the controller knows the status of the motors.  This is useful for all kinds of reason including:

    1. debugging the causes of crashes - the controller could log when a motor has stopped running.

    2. allows faster and better reaction to a motor failure perhaps saving you from a crash at least for…
