Building a from scratch fpv fixed wing with diy components under 50$

This is my first time building a fixed wing. I would like to build something that has the following specifications.

1. Diy flight controller using ESP / arduino or any other cheap microcontroller.
2. Diy ESC
3. Diy ESP/ arduino TX / RX
4. 1 or 2 , 2212 brushless motor / cheap.
5. Diy servo with dc motors.
6. Fpv camera / VTX
7. 1s / 2s / 3s/ 4s li ion 18650 batteries that plug in directly into a battery holder.

From scratch and cheap appropriate size frame that has a pusher configuration so the fpv camera is not hindered by the prop/s. Should be stable for good fpv feed.

How do you think i should go about this and where do i start from the basics? replace a part with already available cheap component where building one from scratch wont be feasible absolutely (cost wise not time wise).

That's an ambitious project to build diy electronics but should be interesting. Can't wait to see how it comes out.

The learning curve is gonna be spectacular. Back in the '70s you could get an OS Max digital radio kit with 4? Servos ready to assemble/build for like a Benjamin. So for starters, need transmitter theory, receiver theory, how proportional servos work, gps, power electronics to name a few.

Don't want to put you off, but when you're done, you are hire-able by any electronic manufacturer in the world as an advanced post doctorate graduate.

Really hope you succeed

I take my hat off to your ambitions. I have 2 degrees with honors, but to set such tasks for myself means to be a genius. I sign up for the sequel and go get some popcorn.

  1. I think you might be mistaking that you can part out many of those things cheaper then purchasing them out right. (many parts are available so cheaply that there is basically no way to make them yourself cheaper)
  2. I don't see you indicate any type of RX control link, the built in bluetooth/wifi that you might get from an ESP/arduino board isn't going to have the range for a fixed wing craft.
  3. for a fixed wing you don't _need_ a flight controller (multi-rotors need them because they are are not inherently stable, a fixed wing will fly straight/level when built/trimmed correctly with no inputs), so you could drop that to save some money
  4. again - analog FPV gear - it is unlikely you can build it cheaper then you can get the base line parts off the shelf.
  5. as to the li-ion battery choice, many of them don't have the C rating to handle the load the craft needs to handle.
