Great videos! One idea here...Your cable weight is all the way at the back, which causes the rear motors to spin up faster than the front ones to maintain level flight. This is causing more amp draw to those motors, (watts) and therefore, is less efficient. Moving the weight of the cable to cg should distribute the load equally on all four motors and give you better efficiency as well as more agile flight characteristics imho.
I've contemplated a project like this I think the answer would be to use a high voltage source and tether and drop the voltage and increase the current on the drone only problem is that step down converter would be heavy also if it could be light and efficient the HV tether could be quite light
I think what you meant to say was putting the two 20 gauge wires would essentially be a 10 gauge wire? Running wire in parallel is extremely inefficient... Two 20 gauge wires in parallel is closer to 17 maybe 16.5 gauge
That's very true. It didn't work at all, What I am working on now is to step up the DC into high frequency and voltage AC then back down to DC on the copter end. The other Idea I have is to run 2 ESC's in series and those 2 in parallel so that I could essentially give it 8S power. Higher Voltage = lower current. Let's see.
So basically, you ended up with a 32 foot piece of wire connected to x? amount of batteries wired in parallel ? Your first part also showed a stack of batteries, but you didn't show how they were connected together for a ground-to-air power supply. A third part video to this project would have be really nice to see.
Hey, Yeah it was a straight power wire up to the drone from a stack of parallel batteries on the ground so that I still had the 16.4V of a single 4S battery.
