It’s close but the Challenger 1/StarTrek/ Kadet and early Scorpion units were double swept and diamond airfoil, the Sky Writer trailing edge is not swept and the airfoil is a wedge with a flat trailing edge. Both are nice but the earlier unit looks better to me.
See below from an old Kadet and a Mongoose to compare. |
