Yeah problem is at high power, twisting the wire like that can blow a high power mosfet and that would be end game for a drone. I've made many different bucks and I also program the logic on microcontrollers. I mean full out morse code that's adjustable within 8k, over 2000 lines of code, a lot of optimizing. My buddy is an ee, even he was skeptical I could push 6v@12 amps through a mt-g2 rated at 6v 4a without blowing it, but went through several designs and probably have the best flashlights in the world right now. They put out around 8k lumens on one emitter with morse code and up to 600 chars programmed in by the user including prosigns.
I was going to send one to selfbuilt at candlepower, but those guys would take it apart and copy the bucks design, so I've sat on it. Still working on the website, but builders will be able to integrate the custom code into thier own designs using a chip that fits on the end of your finger (8 pin soic 8 or qfn, builders choice! or even vqfn)
Emf maybe contained well enough at lower power, but you need shielding at high power. When took my mavic apart I seen the wiring was twisted by dji. My mavic did a lot of weird stuff compass wise, so had to fly her nice and slow most of the time, keep her high. Now, even with the battery overheated 147F in sport close to 100F day, she has no problems after shielding the motor wires. I could never fly her like that before.
Here's a early design of my buck, minus the inductor. tldr; The mavic needs those motor wires shielded. I've tested twisted wire to the emitters in my designs and it's ended with blown mosfets at the high end. Not saying that would happen to the mavic, a lot rides on the quality of the mosfet itself. But I've seen it happen with my own works.
