Kunststoff-Formfinne 5 Satz von 4 - Q20876

Snapped these onto an existing fin can with no trimming needed, and the fit was tight and square. The molded edges are clean enough that I barely had to sand before priming. Four fins per set is handy since I usually build two rockets at a time.

The molded plastic is sturdier than I expected, no warping or rough edges straight out of the package. They fit snugly onto all three fin cans I tried, so the versatility claim actually holds up. Good value for having spares on hand for different builds.

The fins fit snugly onto all three of my fin cans without any wobble, which saved me from having to sand anything down. Molded plastic means they're light but still stiff enough to hold up on a few hard landings. My builds look cleaner with these than with the balsa fins I used to cut myself.
