Estes Cosmic Interceptor Build, Part 17, Filling The Tab Recess

I wish the tabs on the S pieces were longer! If the tabs extended past the flat face of the wing, they could be simply sanded to surface.

The tab recess is shallow and could probably be filled with CWF. I prefer something stronger. 

I sanded down the tabs so the balsa plug would have a deeper fit.

Some 1/8" wide stripes were cut from the leftover fin stock.

These were cut a bit long and sanded for a tight fit.

I've done this before when the tabs were short on the Super Orbital Transport.
