Flew both a 180-hp LongEze and a Glasflugel Speed Canard in a military
applications test program, one of the things I demonstrated was canard
aerobatics.
Basically, I would advise AGAINST any formation aerobatic work.
First, you MUST maintain positive G in a canard--remember that
the forward wing, (canard) is a lifting wing surface, and it basically
works by varying its lift. It really isn't capable of going negative
lift, and frankly, I wouldn't want to be the one to experiment with
this.
Therefore, all your maneuvers will basically be barrel rolls,
(maintaining positive G at all times), and you don't want to be doing
barrel rolls in formation, only axial rolls. You just might pull into
the path of one of your wingmen, and as soon as you start to roll, you
will lose speed, which will cause them to overtake you QUICKLY.
Second, on any pullouts, you have to be careful to not over-pull
on the recovery. It was quite common for me to pull into buffet on the
way vertical out of a loop. And, you want to be sure to get the power
off on any vertical-down direction. These birds will pick up speed like
you wouldn't believe if you have power on, and you could very easily
exceed VNE before you could get level.
With those thoughts firmly in mind, PLEASE be a COMPETENT acro
pilot before trying it in these birds. There is a lot different about
them, and you want to be thoroughly prepared before attempting any acro.
Remember that they are positive-G planes, that must be
maintained AT ALL TIMES in order to maintain control.
Second, REMEMBER THAT POWER-OFF vertical down, and don't try to
rush any vertical-down recovery. If you pull into buffet, then relax and
do it easier. If you are too low, tough titty, my friend. You can't
pull harder.
Third, DON'T do it in formation--you will put everyone in deep
jeopardy, because of the barrel-roll nature of your maneuver, and your
sudden loss of speed in doing the maneuver.
You want graphic evidence of unbriefed formation danger, I have
a video of three Australian planes returning home after the end of
WW-II. They were approaching their home field, and there was a huge
crowd waiting to welcome them home. They were in a Vee, trail planes
slightly high.
Over the crowd, the lead pulled up suddenly, without warning,
just a homecoming kid showing off for the home crowd.
The trail planes took off his tail, he took off both their
wingtips. All three planeloads died. After the war was over, simply
because of exuberance.
Please don't do this yourself.
