This is a quick post documenting the most recent Sendmail setup that I’m testing for a project. It differs slightly from my typical setup on Debian systems, so I’m documenting it here mostly for the sake of keeping notes.

The DJI Phantom 5 is the anticipated new iteration in the Phantom line, which fits somewhere in the “prosummer” tier of the DJI product spectrum. With so little information out, many websites are cranking up their hype machines to give fans some information.

According to Wikipedia, the now ubiquitous airbag can be traced back to a 1941 patent on the use of air bladders for protection during collisions. Nowadays, cars in many parts of the world are required to have them, both for the driver and the passenger. pexels.com An article I read today reminded me of an exchange I had years ago with a dear friend about accessory placement in our cars… Both things clicked in my head.

It has been a while since I published my original Supplier Catalog post and things have changed. A lot. This post is an update, listing the parts I’m currently using to build my quads and the reasoning behind each one. I hope you find this useful.

On this post I’m going to share my latest procedure to configure and connect my FrSky D4R-II receivers in small spaces.

The Loc8tor is a device designed to help you track and find lost items, provided that you had the foresight to attach a tracking tag to it, which is kind of the point of this post. My experience is with the “Lite” version, which relies entirely in RF beacon location tecnhnology to reunite you with your RC model.

Properly mounting a video camera in your drone might not be as easy as it seems. This is why I designed a very simple 3D-printed, adjustable mount that will fit your Mobius, RunCam HD or Foxeer Legend 1 action camera to your quad for a reliable, jello free experience.

Most people trying mini-quads get hooked pretty easily. Racing and proximity flying gets your adrenaline pumping and encourages social flying. Personally I’ve had a couple of interesting experiences with friends…

I like using Afro ESCs for my DIY multirotor projects because they are inexpensive and for me have been working well. However as of late I’ve been motivated to research other options after a second model started showing what seem to be random sync issues. Now, the issue with my 250 combined with my discouraging earlier experience with 690Kv motors was something I could not ignore. For me it’s clear now that SimonK’s firmware, while good for many – including myself with some of my mid-sized builds, one of which made a cameo at the video above – really has issues recovering sync for motors in the “slow pancake” and “very fast” spectrum.

Particularly in small frames you need to be very careful with space and weight, as well as your cable management to keep things tidy and well protected. A way to make cabling a bit simpler I’m experimenting with consists in getting rid of some of the ESCs cables.
