Well, I'm just at the end of my APM 2.0 based Octo build
(this has taken ages, and is based on a unique aluminum # frame variant - pics soon!).
The current take-off-weight is around 3.2KG
Power Chain specs:
4s/14.8v 5000ma nano tech LiPo,
8X Turnigy Plush 30A ESC
8X T-Motor MT2814 / 770KV
8X APC 13X6.5 E Thin Electric props (these are perhaps a bit long for 4s...)
My rough assumption is that each motor would draw up to 30 Amps X 14.8V = 444 Watts.
Multiplied by 8, that should be a draw of 240 Amps, or something like 3,552 Watts...
That's about twice my wife's blow drier power!!!
(Perhaps next build should be a blow drier based quad?!)
For the very short period I have been setting up, I am getting tired of pulling
out the LiPo connectors, and want to insert a Single Throw switch on the main (+) line.
I got hold of a hot water tank power switch rated at 16A / 230VAC, which I guess should well
handle a draw of 3,680 Watts (see attached image).
Also, the switch is DPST, so I can actually send the current through both poles in parallel.
The switch is marked as SW2 in my previous discussion:
