    We all know how hard it can be to stabilize a very unstable system ! The
problem is not trivial at all and I am sure that many people had the same
idea before and were not able to get it done. And besides that the
integration of motors, gears, batteries and control system is awesome. It is
not innovative as a technology launcher but it is a very good example of
good pratical applied engineering.

    If it did not cost $ 3000 I would like to have one. It looks like a very
nice toy :-)

Best regards,
