Peter,

Bipes make a great deal of sense in the present F3A environment with its 
snaps, rolling loops  and assymetric maneuvers in general. And as far as 
speed control is concerned the bipe should have the advantage. Whether they 
overtake the monoplanes in F3A overall, well the jury hasn't even gone to the 
deliberation room yet.

Personally I like bipes, but I like Nat Penton's purpose built mono, The 
Express, even better. Form trully follows function in this design, which Nat 
has perfected in over 15 years of refinement. I would love to see one of the 
top pilots fly this model for 50 flights and really wring it out.

regards
