Methinks that having the necessary RC gear onboard but choosing not to
use probably gets around this, because this means the plane is never out
of your control - even if you're not controlling it :-)
Personally, I'd be more interested in making a miniature helium blimp
that navigates around the house, and it's a hell of a lot simpler to
build (you could even use an off-the-shelf photopopper circuit if you
really wanted to). "TPM" motors with tiny propellers put out a lot of
thrust for their minuscule weight. (Unfortunately not _more_ thrust than
their weight though, as far as I can tell...)
Problem - actual balloons are no good for lift - they deflate after a
while. The expelling pressure the rubber exerts on the gas is obviously
a big factor, but as well as escaping through the knot, I wonder if the
rubber itself might not be completely helium-proof. The first problem
(rubber trying to expel the gas) is easily solved by using a slack
bladder (reminds me of a Blackadder joke...), but if helium can actually
pass through rubber, what else can it pass through - what material
should we use that is helium proof?
(I don't want to have to refill the thing will helium every few weeks).
Waaay down the track, an outdoors unit that uses the sun to extract
hydrogen from rainwater could act as a refilling station for any leaks,
but that's not really plausible right now, and hydrogen gas has some
er... drawbacks... :-)
