It's just that what I normally do is throw a couple of older 600 mah flight packs together in parallel to make up a good ignition flight pack. Works great, but it's a little heavy (and large) on some of these lighter weight/smaller airplanes I convert to "converted" gassers. I have a couple of nice lightweight 1200 mah LiPoly packs I would love to use, but the voltage is of course too high at 7.4 volts. That's why I have the interest in an inexpensive voltage regulator. I did buy one of the more expensive ready made ones, but if I could make one myself much cheaper, I would use that for the ignition pack, and my "high dollar" one for the flight pack.
