Big Girtha Build Fins Part 4

I'd forgotten how big the original Big Bertha fins were. That's a lot of balsa!

I decided to trim them down a bit, it'll still be plenty stable.

I didn't want to mess with the original shape, I just trimmed off 1/8" off all sides.

The Bertha kit comes with 1/8" thick balsa fins, I'm making mine with 3/32" balsa.

For the first time in years, I'll be papering the fins. It'll make them a little thicker and much stronger. More on that later.

Here's the size comparison between the original size and my trimmed down version. Same profile, just a little more streamlined.
