...all I have is my observations using a DMM's here at home and an ocilloscope a few times at work. At the time I did all this I wasn't really looking to right a paper on the subject.... I tested servos direct off the RX buss (which showed pretty good actually) and through extensions of 24,36, and 60 inches repeating the same test with the same servos with the connectors changed out and using the buss. I used a 6 cell 3000mah NiMH pack through 2 powerflite adjustable regs for all tests and the battery to switch connector was a deans for all tests. I never pulled the battery down to dropout of the regs which I had set to 6.2V under a 1 amp load. Although at the higher loads the regs output did droop some due to internal losses. I used JR heavy switches for the "stock" tests and powerflite switches on the buss. Losses though the two brands of switches were similar. A couple tests powering straight of the RX buss (using no switches therefore no extra connections) showed little loss until total buss load was over 4 amps and even then the losses were less than a volt. Adding extensions and switches to the mix (extra connections)is when the real drops occurred. All the extensions showed the same loss at currents below 4 amps showing that the 22awg wire was plenty. The main losses appeared across the connections. So you can make a significant difference in the systems performance just by changing out connectors. If nothing else, changing the connector between the battery and the switch should show a difference in performance in a large plane. My buss is overkill for most applications (IMO) just common sense stuff like keeping the # of connections beyond the RX buss to a minimum or changing those connections to something better, at least 22awg wire for you extensions and on large applications switches and battery packs with 18awg wire, and changing the battery to switch connector would go a long way. Another advantage to using a buss like mine is that if you use matchboxes, gyros , etc. they can be put between the rx and the buss isolating them from any servo loads and giving them a nice constant 5V power source. While the servos can enjoy whatever voltage you want to run on them. So were does all this get us?? Well, obviously, you can fly without doing all this, but doing it will make a difference. Just my 2 cents. If you want graphs well, I guess you'll have to do them yourself...not trying to be a smart**s but I did what I needed to prove to myself what was going on. And I'll be happy to share that info. but I am not going to re-do everything just to make graphs or "proper documentation".
