Papering fins looks like crap...ALWAYS and is a cheap/quick lousy substitute for PROPERLY finishing balsa.
If you don't want to fill balsa in the traditional way on fins, use R/C aircraft MonoKote/Ultracote.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
