Estes Plasma Probe Build Part 13 Main Fin Fitting
Because of the "stepped" root edge, there are three sides that'll have to be fitted to the body.
Fit the fins one by one and mark the tube and root edge as you go.
Most of the fin edges should fit pretty well. A little sanding with the block will get them tight against the body.
The raised glue fillet on the rear ring and engine mount tube prevented the fin corner from sitting in the joint.
Slightly round the corner to go around the rounded fillet.
It takes very little sanding on the corner for a better fit.
Sand a tiny bit off and check the fit.
