Estes Advanced Target Drone, Kit #1913, Build, Part 6, Fin Gluing & Intake Fit

 

There are four fins, the two longest are the "wings".

The large rudder fin is glued on the top,

The smaller ventral fin to the bottom. 

Note the fin line was sanded for better adhesion. The pencil line was redrawn after sanding down the filler/primer.

The wing fins followed. 

The trailing edge is 5/8" from the rear of the tube.

All four fins are glued on at 90 degrees, or standard four fin spacing.

I tried a test fit of the intake shroud.

Look close at the squared front edge. The wing fins have a rounded leading edge, the intake shroud slot is square!

I'll fix that in the next print.
