The Sensefly EBee is the same configuration - Fixed Wing Pusher and the
results are astonishing.
Fixed Wings are robust by design - So for a newbie they should be a lot
more manageable. Yes i lost some props due to crashes but not much
further damage.
I got NAV Launch to work yesterday and basically you throw the wing into
the air and it starts climbing until you touch the sticks. So takeoff
and landing is a matter of throwing and letting it "crash" in a grass
field near you. Although my power/weight ratio is not as good as
expected so it takes a while to gain enough speed to climb.

It flies aerodynamically not by simple force of the props like the Quad ;)
In my configuration i think i get airtime of 45 Minutes or something.
And yes - It glides pretty well ...
I am know confident that i get the flying gear to work - probably not my
proof of concept but it'll work and produce aerials.
And than?
