   I think you should take up the challenge, start now, and work on it through the WC. It has to have gotten boring winning everything by now, right? Stunt has gotten too easy, need a new project.

But Brett -- what will the rest of us do if he wins WC '16 with a canard, or a Fierce Arrow?

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

Do not worry Brett, I am on good way, my Max has tail enlarged to 30% of wing and movable elevator has only 1/3 of that area ... sooner or later ...  ;D

  If he wins with a Fierce Arrow, I will petition the Pope for his sainthood.

   A canard with the canard only 3.33x the size of the wing?

    On the 30% 66/33 tail - way ahead of you on that one, but I have good reason to think that will work. If you get the tail airfoil right.

Aerodynamics aside would not a mid engine Canard have some inertial advantage?

You have enemies? Good. That means you've stood up for something, sometime in your life.

If it was advantageous to minimize moment of inertia, yes.  I think Igor feels that having a long nose on a conventional plane adds more aerodynamic mojo than it subtracts inertial mojo -- that's well above my pay grade, however.

I liked the article in the new issue of MA on an RC Curtiss XP-55 test bed.  Other than getting the initial CG too far back after that was fixed it flew fine.  I think that means it should be possible to design a perfectly flyable canard stunter.  We've spent 50 years perfecting the current layout and maybe 2% of that working with canard designs.  Although it's been tried and works, like any airplane, it takes fine tuning the parameters to do the exact job you want.  And it is quite possible that a canard configuration can't be tuned to fly competition stunt.  But the proliferation of canards on Gen IV and GenV fighters makes one think that they may improve maneuverability(whatever that means).
