Shawn has done it again! Flight controllers nowadays are very well made and widely available. But that wasn't always the case! Back in the day, some flight controllers had to be hacked together from spare parts. But what if we tried to build our own flight controller today, with all our other modern drone hardware?

I built a MultiWii quad for my research project at university 2 years ago. It was fun searching through old forums trying to get as much information as possible. I also built my own frame out of aluminum...which was a mistake, cuz if I landed hard, an arm would bend and never bend back into the original position...so PID tuning became a hell of a thing to do each time. Still got a grade A in it lol.

Yep, I started with a multiwi and then went CC3d in 2014. It is amazing how far flight controllers have come. We use to have a separate osd as well the first ones however there was no way to know your voltage except by feel and time. I remember flying new packs one after another timing them and inching up the timer till I got the flight time close. We all used to use the tape to mount everything and Velcro straps for batteries that always ejected in a crash.

@steev0373 2 жыл бұрын

Cool stuff! I built the flight controller for a drone for my uni project last year using a PIC18F4321. I managed to get it to fly and level itself running the code at 50Hz haha. It was a little easier because I used a GY-25 chip which outputs angle rather than having to address the gyro and accelerometer directly, but even still it was a difficult feat to get that bird in the air! For comparison, my Microcontroller had a 32MHz clock, 512 Bytes of Flash memory and 256 Bytes of RAM whereas a modern F7 FC runs at 216MHz, with 512KB of Flash memory and 256KB of RAM!

its crazy how fast flight controllers evolved. while I havent flew a wii FC, I did start out with the kk2.1 back in 2012-2013 on my 250 hobby king frame. I was more into microdrones though so I was using a lot of hubsan and walkera FC with brushed motors. The very first configurable FC I did build with was the AlienWii with dsm2 satelite RX. They were $50 for a fully configurable FC in MultiWii. I didnt get into 200+ size drones until I built a NAZE32 drone.

That looked fun. I've been at FPV drones since 2018. They were pretty well sussed out by the time I got to 'em. I was into r/c in the late 70s, building 1/12th-scale Tamiya kits, and using a 2-channel radio, before taking a three-and-a-half decade break. I never dreamed of the kit we have today back then. Even 2018 gear is literally Buck Rogers stuff compared to what was on offer in the late 1970s. And much, much cheaper, relatively speaking.

I wasn't early enough for Multiwii, the first quad I had ran CleanFlight. It was the last version before Air Mode came in, so 1.7 I think? Anyway, yeah, quads back in the day were a handful. I remember that it was a good idea to plug in with the quad level on the ground, otherwise the gyro wouldn't have a good level. So that might have explained the inconsistency the guys had between flights in the video. Probably needed to give the guys Gemfam 5030 bi-blade props on a 3S pack for the rfull experience though! Or maybe slightly older school and build an Elextrohub. I think at a certain point the Electrohub was everyone's first quad!
