Arthur T Knackerbracket has processed the following story:
The availability of cheap and powerful RC motors and electronics has made it possible for almost anyone to build an RC flying machine. Software is usually the bigger challenge, which has led to the development of open-source packages like BetaFlight and Ardupilot. These packages are very powerful, but not easy to modify if you have unconventional requirements. [Nichola Rehm] faced this challenge while doing his master’s degree, so he created dRehmFlight, a customizable flight controller for VTOL aircraft.
[Nichalo] has repeatedly demonstrated the capabilities of dRehmFlight with several unique aircraft, like the belly flopping RC Starship we covered a while ago, a VTOL quad rotor biplane, VTOL F35, and the cyclocopter seen in the header image. dRehmFlight might not have the racing drone performance of BetaFlight, or advanced autopilot features of Ardupilot, but it’s perfect for getting unconventional aircraft off the ground.
dRehmFlight on GitHub.
dRehmFlight is a simple, bare-bones flight controller intended for all types of vertical takeoff and landing (VTOL) vehicles from simple multirotors to more complex transitioning vehicles. This flight controller software and hardware package was developed with people in mind who may not be particularly fluent in object-oriented programming. The goal is to have an easy to understand flow of discrete operations that allows anyone with basic knowledge of coding in C/Arduino to peer into the code, make the changes they need for their specific application, and quickly have something flying. It is assumed that anyone using this code has previous experience building and flying model aircraft and is familiar with basic RC technology and terminology. The Teensy 4.0 board used for dRehmFlight is an extremely powerful microcontroller that allows for understandable code to run at very high speeds: perfect for a hobby-level flight controller.

A bunch of us built model rockets and launched them (in Mira Mesa, for you Sandy Eggans). This was early 80s, way before the www. There were 5-6 of us who met every month to launch our rockets. None of us bought kits, instead we bought, I dunno what they were called but basically "buy this box and make 6-7 rockets from the pieces".
I remember one guy, can't remember his name but remember his face, who made a gyro. Rocket went up, fins were on rubber bands, engine ejected, fins changed position, rocket landed like a helicopter. Once we saw the concept 2-3 of us built the same thing next month.
Me? I tried to build a MIRV. That is, 1-2 launch stages, then shoot off 3 rockets. Never got it to work and trust me, I put a ton of effort into it.
One day we went to launch our rockets and there was a bunch of earth moving equipment there. We figured they weren't clearing out landing pads for our rockets and, a month or two later, our little club died.
Note 1: If you know where the Design Center was back in the early 90s, which became the Qualcomm headquarters mid 90s, that was our launch pad.
Note 2: One day the VIPs from New York, who owned us, came to visit. James had his rocket on his desk and got into a long conversation with the NY VIPs about it.
Note 2a: James had a degree in geology, yet was designing electronic circuit boards
Note 2B: James won an EETimes contest, got a brand spankin new Corvette out of it.
Note 2c: The 80s were a wonderful time.
Note 3: There was a 7/11 bottling plant nearby
Note 3a: One of my rockets landed on it's root
Note 3b: During lunch went to that plant, and ended up talking to the guy who ran the place for 30 minutes while he got some dude to recover my rocket.
When the dust settled America realized it was saved by a porn star.
