				All right guys and gals, what do owners of Pitts Specials do, or many  of the 
 other aerobatic planes??  The Zenith, from all engineering studies  on tail 
 length, volume etc. should be a nice flying plane, should you shorten  the tail 
 a foot or so maybe it would indeed be  "twitchy".
 
  
 Base your choice on statements from those with a variety of  experience in 
 the similar aircraft, not Cessna, Pipers and so on.  I've  flown X-C in all 
 sorts of aircraft before autopilots were available and guess  what ~~I'm still 
 here.  Twitchy is not an engineering term to the best of  my knowledge.
 There wouldn't be so many Zenith aircraft built if they were  "twitchy"~ 
 (assuming that means impossible to hold on altitude &  heading) I'm sure the 
 designer knows a lot more about  designing than many who report on the twitchyness 
 do about handling  characteristics.  
  
 That being said, are you building to fly with the auto pilot  or to fly for 
 enjoyment??  I've got 25000 hours and still enjoy flying by  hand, so what if I 
 have to go the awful task of changing the fuel tanks to keep  in balance, or 
 moving the elevator trim as fuel burns off.  This is part of  flying.  
  
 Homebuilt aircraft are normally not as heavy on the controls  as most 
 production aircraft, and the majority of pilots I fly with giving flight  reviews 
 (CFI 40+ yrs) are not smooth on the controls unless they own their  airplane and 
 fly at least every other week.  ~~ hence "twitchy" feeling to  them. Aircraft 
 should be flown with the fingertips for a smooth ride for  pilot and 
 passengers. 
  
 
 The Pitts Special isn't a nasty flying aircraft, it does  just exactly what 
 you tell it to, nothing more, nothing less. Knowing what to  tell it is the 
 problem!  Pilot Proficiency = Safety
