65" twin boom FPV cruiser

Instead of using packing tape to cover the depron I used document laminating film, often referred to as New Stuff in the RC world. It is ironed on with a warm iron before bending the airfoil and fuselage, and works very well. It's tougher and easier to apply than packing tape. How to video below. 

Construction

See the depron wing build and Spectre overview videos for the basics.

Additional strengthening ...

6x1mm CF strip glued along the front of the elevator

Heat bent UPVC brackets for the rudder to elevator joins.

 Full length wing spar made from 2 Skyshark P4X spars joined with an internal 80mm solid CF joiner and epoxy.

I used twin rudder servos rather than one servo and a long vulnerable connecting pushrod between the rudders.
