 Cliff, 
  
I have a fast R/C  sub (500 mm long) When sharp 
turning at full speed, it shows a massive 40 deg. roll (the normal lean angle 
like a  motorbike, no battleship. It dont has the tendency to dive. 
 
I think there is no problem as our psubs would not make 
such extreme manouvres. 
  
Grs, Emile

  Question: 
  When a sub is turned sharply at speed, using only the rudder, will it dive as 
  well?  It seems to me that some 
  roll would be induced by centrifugal forces on the heavy part of the sub 
  (lower part) which would cause the rudder to be in a non-vertical position and 
  point the sub in a turning and diving attitude.  Would this be a problem at speeds of 
  4-6 knots and if so, is it correctable?  
  Thanks, as always, 
  Cliff
