Icon A-5 Spin Resistance

The flight testing involved here has already been done, but the video at the link below is very persuasive regarding the results.  As I look at the control deflections just as pro-spin controls were applied, I do notice that the rudder deflection of the A-5 seems to be a lot less than full-deflection rudder on a lot of other light airplanes that I have flown.  To a degree this makes sense, since the rudder is right in the propeller slipstream and as long as the plane is being powered it will be more effective than the typical rudder.  That fact opens the question of what happens if the same controls were applied with full power, but the full-stall lateral control seems to be quite powerful, so it may not be an issue.  I'm impressed.
