the leads/antenna could be small gauge with power sent via high
voltages/low current, since the motors could be PWM driven with the
onboard processor or a simple buck convertor.. Taking out the LiPo
battery saves weight too. Any Maker's that have hacked one? btw
having flown a MEMS gyro in a rocket, I don't think the MEMS gyros are
stable enough for long term unattended hover positioning, so periodic
radio position control would probably be needed, or maybe a GPS lock.
I think optical station keeping would be easiest. Most of these things
have a video camera looking down, so what you'd do is set up a colored
target, and it would try to keep it centered.
Of course, a Kiteoon would be easier.

Hi Mirko,
I've paid about $200 for a kiteoon, locally. The 8-to-9 foot diameter
WX balloons are usually about $30 each, so a kiteoon is definitely more
expensive -- but, the kiteoon is reusable, whereas the latex WX balloons
are not. Once they stretch from use and the He starts leaking through
the latex (which it does, within about two days), the WX balloons are
good for the garbage bin.
