Estes Plasma Probe Build Part 7 Fin Prep - Uh-Oh!

The laser cut "balsa" parts were easily removed from the sheet.

On this kit, the "wedge cut" from the laser was really apparent.
If you didn't square them up, the root edges wouldn't sit at a 90 degree angle to the center line of the model.




The eight forward strakes look like small launch lug standoffs.

They are small and loads of fun to sand square.




I didn't notice the difference in the fin thickness until the forward and rear fin pieces were stacked. The thickness difference is subtle, but would require some filling. The balsa sheet that had the forward fins was thinner on one side so two of the forward fins were a bit off..

I could cut out new fins from balsa sheet of the same thickness - or,
Sand the thicker main fin down to the thickness of the forward fin.
I'll cut some new forward strakes in the correct thickness.
