Phenomenon Update: Look for Record Attempt in Summer 2011
#21
Are you sure? The current placement of the canard may cause dynamic instability and potential pilot induced oscillations (if there is direct linkage in the control of the canard wing). I’d certainly like to see the wind tunnel data before I got anywhere near 200 knots.

I thought I spied some type of pivot mechanism in one of the pictures but you may be right (in which case there’s no risk of a PIO event). However the dynamic stability issue may yet be a concern with the canard’s current location. Can anyone familiar with the project confirm if the incidence of the canard is indeed adjustable and if so by what means?
Thanks,

It was my understanding it was gyro/computer controlled ...

My cunards were cockpit adjustable and work well being that far foreward they have a good mechanical advantage,What I can't figure out is why the fairing in of the tunnel/cockpit was done in that manner, there is a better way of doing that.

I believe that is III.

I believe Al Copeland Jr confirmed in an interview(?) or article that the canard wing was controlled via computer which sensed lift weight at the front and adjusted angle to either increase or decrease according to speed. If it was all automated via computer, it would be a fantastic trim wing! I can't wait to see thing thing at full speed, it will be a sight to behold.
I for one, hope they can achieve what they have set out to do.
