Here's the cross section airfoil of the largest fin.
Shaping was done with 220 grit sandpaper on a block.
The nose cones were glued into the pod tubes.
Sand their shoulders to the diameter of the BT-5 tubes.
I went ahead and filled the balsa, tube seams and the body tube breaks.
The assembly on the right has been brushed with thinned CWF.
The assembly on the left is after it was sanded sown with 400 grit.
