Estes Guardian Build, Part 5, Rear Fin Gluing

The smaller rear fins were glued on first.
After the first fin was glued on a thin masking tape strip was set down to line up the leading edges of the other two.

The large front fins were glued on with the rear trailing edge at the top of the tape strip.
Two craft strips (Popsicle sticks) were set on either side of the fins to assure they were both straight and in line with each other.
Clothes pins held the fins on while the glue dried.

Fillets were hard to smooth out in the small area between the two fins.
A Q-tip got in where a fingertip couldn't.
