No. IFI controllers are way heavier than they need to be.
You could buy a much lighter controller with nearly the same features. I would also suggest a lighter battery. But the same type of electronics should be fine, and you have experience in them.
(i'm talking about the old controllers, not our nice new ones.)
Of course, If I were building an airship, i would totally use hydrogen, i mean, if its unmanned who really cares if it explodes? Hydrogen will weigh about half what helium does, and therefore you get added lift! Not twice the lift, but a little more, and thats what counts.
Heh, an hydrogen isn't THAT dangerous . . i fed a test-tube full to a candle once (result of electrolosys) and all it did was make a flash and a whooshing noise . . .
so in R/C airship quantities, it should be relatively safe . . . as long as you don't TRY to burn it or anything.
