What are these in the fin root?

[YaKnow!]

I was looking at a picture of a rocket and noticed a technique for attaching fins I have never seen before.
This appears to be epoxy blobs maybe?

Not sure, and I was wondering if someone could tell me what I am looking at.

Looks like a simulated weld line to me. Nice and evenly spaced though!

Is it a 3D part?

That is a Scott Binder / Fusion Rockets Arrow X. The manufacturer’s site photos are tough to make out, but it does not appear the kit offers that additional detail stock. I think the builder decided to ‘play up’ the missle-like design and add those greebles. Makes for a nice effect.

Thanks!
And here I was thinking they were a new way to do fin roots and they structural.

The kit includes a 3D printed nozzle for display. So I would guess those are 3D printed parts for scale looking detail that may not be part of the kit - but sure look pretty cool. It also includes the decals shown which I think look really nice.

IIRC Those detail pieces are actually laser cut heavy cardstock, and they fo come with the kit afaik. The tail fin locks/actuators are laser cut plywood.

From the description: “Kit includes laser-cut 1/8" aircraft quality plywood fins, laser-cut detail parts, and a custom 3D-Printed plastic simulated nozzle (not recommended for flight)”. Sure sounds like you are right, I missed that in the description before. Pretty cool looking kit and helps explain the price.

Scott Binder is one of our local vendors (and only a 45 minute drive from me) so I see lots of his kits and his prototypes as well, he has some outstanding designs and the ArrowX is one of the coolest IMO.

I really like that fin design. Pretty slick rocket right there
