Nah, all Lynx have the same rotor configuration! The Army Lynx is more liable to carry out loops and rolls due to its internals!! The RN Lynx has more 'boxes' inside to rattle about and affect the C of G.
Also the Bolkow 105 is a more than competent aerobatic helicopter, capable of looping da loop and defying the ground!!!
I know helo's with rigid rotors are normally designed for full aerobatics but that isn't to say articulated or semi-articulated rotor head can't do the odd stunt. (Maybe they never told the pilots!!!!!!!!!):angel8:
