Power distribution.

I have a gryphon PDB for my hex build. It's rated for 260a continuous or 320a peak. Being a technical guy I've looked into the specs which tell me it has 2oz copper. So I looked into what that means. It basically means 1 sq' of said thickness weighs 2oz. As far as how thick it actually is with a bit or research I found out it is 2.8 mils or 0.0028".
Now I'm thinking that is crazy thin with a very low thermal capacity. The gryphon looks cool but I'd have a better safety margin by using 1mm (0.0393") thick copper sheet and making my own. Just talking out loud here guys. You are welcome to join in. Cheers

Our bus bars are 1.5 mm thick solid oxygen free copper machined to our design. These are used for and included with our HC-800 and Hc-1100 airframe kits. They have been tested to 750a at 24v... Never a brown out... Even with U7 and all on forward agressive flight. The challenge is in the soldering. We use mini butane torches to get the solder to flow. Visit the website and watch the soldering video....it can get challenging for some.. This is why we offer the assembly as a service. I hope this clarifies your questions.

I weld, solider etc and I'm pretty good at it. You just proved my point. Other than the weight factor, thicker is better when it comes to power distribution. I may just use my gryphon ones for looks and to hide the copper. bond 1-2mm plate underneath.
