We have just rebuilt our REBEL & received our new C of A & are just about to embark on a new flight test program to asses the planes' new handling characteristics with the leading edge cuffs that a friend (aircraft design engineer ) and I have installed - YAY !!!!!!!!!!!!
We'd really like a bit of input from those who have leading edge cuffs already fitted to their plane (Rebels or not) - as to what to expect / what the cuff did to :
1) The Centre of Gravity - ( did it move Fwd or Aft ? )
(my Neanderthal logic estimates that as the leading edge moves forward - the Centre of Pressure should move forward also (there's more wing chord / & area now) ... and therefore the C of G should move forward slightly - ( to keep in with the "most wings / planes will balance at about 1/3rd chord back from the Leading Edge" rule ) also ... Yes ?)
If that is so ..... then I reckon we should be REMOVING some of the 10Kgs of lead shot I have placed in the tailcone area ( to balance the "light weight" IO-320 with a NOT shortened firewall) ... Yes ???
2) The RANGE of C of G - (did it get bigger / smaller - or stay the same & move forward overall or aft overall)
3) Any salient points to keep an eye out for ?!?
AS always - your thoughts and opinions are gratefully received !
