New Way Mars Snooper II, Build, Part 6, Fin Shaping


The fins are laser cut, and like all laser cut parts there are charred edges.

I see plenty of builds where the fins are cut free from the sheet and the charred edges are left as is. The glue doesn't stick as well to burnt ash.

The fin on the left is how it looks right off the sheet,
The right side fin has had the edges sanded and cleaned up.





Lots of balsa in this kit.
Not as much as the original Mars Snooper - the engine coolant vanes are now cut from thick cardstock.

On the left are the smaller upper fins,
To the right are the two piece main fins.



The leading and trailing edges of the fins are rounded.

I didn't sand the rounded outside corners. 
Does that make sense? 

 




You can check the roundness of the leading and trailing edges against a dark background.

Ideally, a rounded fin edge should be a half circle.
