Though I do not post every test as boring as it would be, I am coming to the conclusion I need to alter the power distribution strategy. First is that peak wattage should come to about 1200-1300 watts with an average below 1000 in total. That being said only two power supplies are hard pressed to handle this for hours on end. Reducing the load below 80 percent of the maximum of a power supply is really a requirement at this point. At this time the top 6 motors and bottom 6 are on their own circuit. This would mean 500-600 watts each surpassing that 80 percent goal. The second improvement that needs to be made aligns with a lighter power to weight ratio. The need to custom build a power supply is here, and for the purpose of both efficiency and redundancy these 12 motors will move from two groups of 6 to either 3 groups of 4 or 4 groups of 3. I am using two DJI power distribution plates which will no longer be used in the new power distribution grouping which may reduce weight if removed, but they are also part of the frame at the moment. The power tether weight can be halved by running 220 volts instead of 110v which was already in the works. We also may 3D print a new power supply frame that doubles as landing gear because the ones I have are very flimsy and flex out of shape with the slightest twist when landing.
