I suppose the newer Saturn SE was enhanced
Bo,
Main changes are -
Ailerons made shorter and wider
Wing made lighter by using cutouts (honeycombing as we would call it now)
Nose lengthened by 1/4"
Tailplane lowered 5/8"
Thrustline lowered 1/8"
Rudder shape changed and subfin added.
More powerful engine - Webra Speed & pipe.
