Just be sure and leave the canard off if you don’t have
the wings on…..
In one of the early CPs (Canard Pusher newsletter for you
non-canard types) there was a builder who had his engine mounted as well as his
canard and when he needed to talk to some other builders on the other side of
the airport, he would fire up the engine and drive it over to the other side of
the airport.
One day during the return trip he decided to setup on the
numbers and give it a shot.
It was tracking great and he was approaching rotate speed so he
gave it a little back pressure to see if the canard would come up. It did but
it rose up so high that the prop began striking the runway, The canard would
not respond to any control inputs because of the AOA it had achieved.
Now the prop is hitting the pavement so hard it’s causing
the plane to pull to one side. Eventually it became totally uncontrollable and
left the runway coming to rest inverted. Fortunately the tower was observing
and got him some help right away.
Of course the FAA had to be involved as well. It turns out that
they did not cite the pilot.
Drum roll please ……..
Because there were no wings on the plane ………
they determined there was ‘no intention to fly.’

Subject: [FlyRotary] Taxi Testing
For
those Canard drivers out there:
Does
anyone know of or can think of any reason why I should not perform some taxi
testing without wings or canard in place. I would like to trailer my 173
to the airport to run some taxi testing to record data on my cooling system,
but do not want to install the wings and canard since I will be bringing it
back home after the test. I do realize that rudder authority would be a
poor, so this would only be done on a calm day.
