Hi Robert, planning to use the Powersystem SportPlus into a 80'span Twin Otter along with Futaba R6008HS 8ch reciever, and 10C transmitter. Though it's not that heavy plane neither has multiple servos per surface, I'd like to have rendundancy and good power distribution thru its 10 servos.
1) How do i get out 8 servos output thru the R6008hs; not very familiarized with this reciever.
Not quite sure what you mean? The PowerSystem Sport Plus has 8 channels so you would just plug channels 1-8 into the receiver channels 1-8.
2) Engines are glow, can i use the onboard Ignition Cutoff output to plug directly on/off Scale Lighting?
Yes, the Cutoff is basically a switch. It can handle quite a bit of current, your limiting factor is really the connectors.
3) With the following sequence:
lipo+swith hd +PSP
can i charge both lipos thru its balance plug using 2 different chargers?
No, you still have a common ground. You can never charge both batteries, with a dual-charger or 2 chargers, when they are plugged into the system. You have to break the circuit and the only way to do that is unplug a battery.
