REFLECTOR: Elevator Cuff size? Aileron gaps 1/8th"?

[Scott Derrick]

I removed the cuffs form my elevators.  Increased elevator authority at 
slow flight,  increased purposing during  canard stall,   reduced stall 
speed of canard during landing.  If I land hard, or with firm contact I 
need to pull up on the elevator a bit to stop the nose from coming down 
prematurely.  Is that what you mean by nose drop?

I think removing the cuffs improved the performance significantly.  
Never looked back.
