[NSRCA-discussion] Canalisers etc.

[Matt Kebabjian]

In fact, most planes that have the silli thing don't need it. The real question is does it reduce pilot workload and the answer is mayhaps......Rudder and Yaw become more effective but not for reasons many think. The real reason is simple and fundamental. 
If the pilot handles rudder poorly, it doesn't make a hill of beans difference how effective it has become by adding this appendage.

Maybe it looks kool and maybe it doesn't. But it doesn't weigh zero.

One of my parameters is that anyone should be able to build it from plans, should they chose to do so-and it must reflect current lines and complex shapes-but must meet aerodynamic parameters/requirements first. It will be a challenge-but it can be done.
