Nice flight computer! Unfortunately, there are several design issues you need to fix. Your decoupling needs to be mlcc and as close to pins as possible, not tht. As far as I can tell, you also don't have any loading capacitors on your hse, and your reset circuit won't work. There are also several grounding issues, your micro sd card has some unconnected grounds, and power ground isn't connected to ground anywhere. There's also a clearance issue with a via and trace under your mcu, that won't be able to be manufactured. To save on costs, you also should handsolder through hole components, jlc shouldn't assemble them. Best of luck with your vtol!

changed the shortfall component
i changed the shortfallEd components so that i can manufacture them also i did some upgrade to the flight controller like i widened the 5v traces and 3.3v traces 
in jlc pcb 
i selected 2 pcba and 5 pcb for the cheapest outcome
i have some coupon but i the 20dollar one will expire in 6hours i will play it safe and choose the 9 dollar coupon so even if the coupon expire i can still pay
so here is the final price

jlc phase
i uploaded the zip file and the bom and cpl to jlc pcb 
after a lot of choosing component i finally got that result 
Unfortunately there is still some component non available showing as shortfall i will try to replace them without changing too much
here is the price honestly i was happy because from the last try it was 190 dollar now its 130dollar
next session i will replace the shortfall components :) and set up the readme

Remake
finished the remake it looks much better 
i will try to setup the github add a readme and the correct structure to hopefully pass and get my flightcontroller between my hands

new mission
after putting my flighcontroller in jlcpcb i saw that the component i choose were very bad choice either rare and expensive or unavailable no suprise that my flightcontroller cost 194$ 
so i changed every component that was deemed to big and not exact to reduce cost 
but when returning to check on the pcb ... everything was combled 
finally i took the decision to restart the routing this time better than last and even smaller

advancements
well i started designing the flight controller i named it Flighty
I started by selection of the component the goals and its needs the schematics i made it to be easily solderable and cheap to repair i will be using THT components 
- the fully finished schematics

Researching and watching explanatory videos
i am currently watching and reading on how to design flight controller i hope to be able to finish this project before the end of blueprint im following notaroomba guide
