That vertical stabilizer nails it down. I've got my own Storch build going on, but it's on hold at the moment. My build time is so very limited, but I've finally got the plans stitched together for H.B.s EAF 2D3D! It's only taken me about two weeks just to print the plans and stitch them together.
You've got a wonderful build going on here! I'd love to finish my Storch with you. I've got to finish the 2D3D, and Lord knows how long that will take me. Then it's back to the Storch!
Keep us updated. I'm following this thread, now. When I can get back to my Storch build I'll drop you a link. I'm looking forward to both our maiden videos!
