Changes made to Saturn SE are:
Aileron chord to 1 3/8" from 1" and shortened to maintain area
Cutouts in wing and use of 1/64 ply covering to save weight
Nose lengthened 1/4", made more pointed to take a 2 1/2" CB spinner
Stab lowered 5/8" to bring in line with thrust line
Thrust line lowered 1/8"
Rudder new shape for better knife edge, and sub fin added
