    There were numerous COZY III's and MKIV's (well, a Rutan derivative, as are the Berkuts, of which there were a couple), Long-EZ's, Variezes and one SQ2000 (another Rutan derivative variant). I didn't see any E-Racers, Defiants, Vari-Viggens (I think there's only one still flying) or other more rare designs. Strangely, I didn't see any Velocities - there are usually a few at the generic canard fly-ins, although they tend to stick to their own. I believe there were 40 or so planes total - maybe more?

    There were, of the long EZ, Cozy and Variez, about 20-25 planes in total plus the Boomerang and Catbird

    The only mention was that "I'm tired of laying on my back grinding carbon fiber" when a question was asked mentioning it in regards to what's next.

    I didn't count, but I'd go with Marc's estimate. There was a pretty good turnout. Thankfully light on RV's!

    Never even heard of the ship later identified as the "Speed Queen 2000" (post # 25, seventh pic down). Despite it seems that it lifted the name from a household appliance from the 1950's, it was a bizarre mix of slick and crude. Sleek fuse profile, but the gear legs were literally bolted to (and standing proud of) the bottom of the wing like an afterthought. Also had significant AN plumbing hanging out of the bottom of the wing, headed toward the fuselage. Looked like maybe brakes or fuel.

    The owner said he was out of Corona. Cruises as 165 mph with the "climbing prop" but he has a new catto coming that should make it cruise at over 200 mph.

    Going to pull a mold off the engine cowling to make a cleaner one he said.

    A friend died in one in Mobile AL about 14 years ago. Got too slow trying to reach the runway and mushed in. Likely would have survived, but the seat backs have no support; collapsed & got his head/ neck.

    I've got a question. After recently watching a video a comment was made about the rudders.. They move independently of one another?

    How the hell do you control them in a turn or ? How many pedals do you guys have in these things?

    Press the right pedal and the right rudder deploys outward. Press the left pedal and the left rudder deploys outward. The rudders act like tip drag brakes as much as they do ‘rudders’. Press both pedals and they both deploy outward becoming drag brakes. Typically, the brakes are actuated at the bottom of the rudder pedal travel, bringing in brakes for turning as soon as you have exhausted your rudder travel, without the need to press on a different part of the pedal. Press both pedals together to the bottom and it activates both brakes.

    Paul Lee, IIRC.

    There was another crash with similar results (however, due to Mazda engine failure and a deep stall due to CG issues). I've got an accident report here:

    Most of Rutan's and derivative canard designs have independent rudders. My COZY does, as do all VE's, LE's, E-Racers, Berkuts, Velocities, etc.

    Same as any other airplane - you push on the rudder pedal to center the ball, and one of the rudders will move outboard. The other will not move.

    Two. Push the pedal to move the rudder - when you reach the end of the rudder throw, push more to engage the brakes. Couldn't be simpler. Push both to get extra drag in the air, or to brake on the ground. Just don't land with the brakes on.

    Sorry - I missed your response and repeated most of it.

    This is a common misconception about the rudders on canards. ~90% of their effectivity is from lift generation, just like standard rudders on conventional aircraft. A much smaller part of the yaw generation is due to excess drag off the aircraft centerline. The reason for not deflecting both at the same time is that it VASTLY simplifies the control system - don't need a cable loop from wingtip to wingtip - not because the drag from the outboard rudder would offset the effect of the inboard rudder.

    What makes the rudders return back to neutral? I mean in other aircraft one pedal counters the other and here I can see that would not be the case.

    Aerodynamic forces, and on the ground, a spring.
