Estes Gryphon #7280 Build, Part 6, Wing Assembly


The wings were glued up on a flat, clean counter top.
Front two sides first,



Rear piece second.

Looking at the main body I did a dry fit check of the canard. It seemed too tight, probably because I have filled and primed the balsa before gluing it in.

A few passes with a flat diamond file opened up the slot and kept it square.

The two rudders are glued into the slot over the wing joint.

Use the alignment tool to get them at a 90 degree angle.






Both rudders were glued to the rear of the slot. This left an open spot at the bottom front.


FIX: For easier filling, I shaved a balsa wedge shim longer than needed.
It was glued into the hole, then cut off and sanded flat after the glue dried.







Here's the rudders in place with glue fillets applied.
