Cool, Thanks. I was thinking that if I ran series/parallel, using 4 packs, which are all the same age and are very close in mah when charged, I could increase flight time. If anything it will at least allow me to try out the plane, and if it goes in, no worries. The Hacker setup is in a Funtana 90 S, which on a Sim snaps wings off if flown too hard. I have also heard from others its a PITA to setup with the dual elevator servos. I can at least try it and if it isnt to my liking, then no money wasted on big packs.
Thanks!
