Since last update my AutoQuad hex has gone through major changes. I switched to lower kv motors and significantly larger props (12" -> 17"). Flight time almost doubled and so the current nearly halved. This got me thinking. Maybe I could move the ESCs from the prop wash under the frame. Maybe even loose the huge heat sinks! I did fast tests by removing the heat sinks and placing the ESC32 inside an enclosure (to isolate it from cooling stream of air from the prop). I ran few tests with high throttle and found out the ESC remained relatively cool. So, I went onward with the plans and designed an integrated ESC32 holder + power distribution board to be mounted under the frame. I already milled it from double sided PCB laminate and soldered first ESC32. Five more to go.
What do you think?
