I'm considering trying to build a plane. Like an earlier poster, I'm definitely a do-it-yourself, crash-and-burn-a-few-times, kind of person. I'm definitely not interested in joining a club.
I have four questions for you experts out there. I've tried to find answers to some of them, but the world seems to be divided into "electric" and "gas" and I don't see a lot of comparisons between them for the beginner...
First question: for a fairly small plane (maybe 24" wingspan, tops), what are the tradeoffs between gas/electric power? Is it even possible to take a plane designed for gas power and swap in electrics? Seems as if the battery weight forcomparable power would be a killer, but I don't have the information to work out the numbers, and some of you surely have the experience.
Second question: My guess is that electrics tend to fly at lower speeds than gas-powered planes. Can someone give me a guestimate of the speed for a trainer-type plane in both gas/electric? I live in a windy area, and if the plane can't make headway into a 20-knot breeze, it's probably no use to me.
Third question: Are electrics comparatively silent? I'm sure that there's prop noise, but I assume there's no high-pitched whine like with the string-controlled plane I had in 1965. Thoughts?
Fourth: Can someone give me a hint about the duration of flight for some low-end combination of batteries/motor/prop on a trainer-type plane? I *know* that's like asking "how fast does a boat go?", but for sailboats there actually *is* an answer: monohulls tend to go between 3 and 7 knots, with dinghies at the 3-knot end, and 40-footers at the 7-nkot end. An answer that's even as rough as that would make me completely happy. :-)
Thanking you all in advance,
