falcon12,
Interesting article about the electrics in the Boeing Airfix kit (aka as 787).
http://www.flightglobal.com/articles...ric-dream.html 1.45MW (rather than 1.45 milliwatt, ah those journalists) installed power, with four 250kVA
starter-generators.
So electrics may be making a comeback (note to
javelin 
).
But I'm sure this is already being discussed elsewhere... let's stick to the 112V DC here. I'll try to collate all the info, just for myself... no wikipedia aspirations.
For an instant I thought: "Ah, anything with an Avon", but they must have come in different flavours... IIRC the Canberra used gas cartridge starters.
