I have Hitec HS-81 servos, I guess I will use them, but I would have preferred to use the Futaba. I just figured with the modifications of the fully-sheeted plane it would be best with Futaba.

Fuselage is going to be 24 1/4" length built entirely of 1/8" sheet balsa, including formers. Stab and rudder will be 3/16" sheet balsa.
Wing span is 35" and 6 1/4" wide and will be mostly sheeted.

Will weight about the same as the Chea-Pass, and that recommends a .10 engine. I believe the 450 will be enough.
