Angle of fins on a FT Delta?

[SoCal Perky]

Hello,
I'm scratch building a FT Delta and I am trying to determine what the angle of the vertical fins should be. I'm thinking 12 or 19 degrees. I seem to remember having a couple of angle gauges I got with the original kit, but can remember if it was 12, 19 or ?? degrees. Thanks for any help...

I think theres a fin gauge on the plans - i built mine from that.

its not one i fly very often at all - good intro to elevons though - took me a while to realize it wanted a good amount of airspeed (vs the flyer) to want to turn

i went to the sparrow shortly afterwards

Just checked the CAD file, the fin gauge is approximately 12°
