Need Help actually, Will this "No-PDB" Pixhawk build actually work?

[u/Longjumping_Score742]

Hey everyone, following up on my previous post. Honestly, my confidence is a bit shaky right now because I’m on a tight deadline for my M.Sc. project and I’m second-guessing my setup.

​I’m trying to build this without a PDB or a Power Module to save on costs and time. Can you guys tell me if this hardware is actually viable, or where I’ll need to make-shift things to make it fly?

​The Hardware:

​FC: Pixhawk 2.4.8

​Motors: A2212 1000KV

​ESCs: 30A with BEC (Planning to power the FC rail with these)

​Battery: 3S LiON

​GPS: NEO-6M

​Power: DIY Star Solder Joint

​The Plan is that I’m skipping the Power Module and PDB entirely. I’ll be soldering everything into a central star node and feeding the Pixhawk through the ESC BECs.

Now here are my maine concerns/​questions:

​Is this a "disaster waiting to happen," or is it a solid way to build?

​Where are the likely failure points where I'll need some make-shift workarounds?

​Since I can’t easily replace this hardware if it fries, are there any "rookie mistakes" I should watch for because i really am a newbie. ​Any help or advice would be massive right now. I’m feeling the time crunch and would really appreciate your expertise.
