The surface is pretty smooth. You can ask the others that have seen it for their opinions. I have no intention of post-process smoothing.

I thought about the finish too but any ridges look to be running in the direction of airflow so I would have thought wont make much difference.

UFO, what is stopping you from printing the elevon as part of the main wing?

Yah. I've oriented the prints so that there is minimal layers perpendicular to the airflow.

The elevons are printed out of HTPLA+ rather than TPU. So, the filament difference is why. I could use a multi-material extruder and have them fused together, but the waste from those is astronomical. As it is, the elevons just slide on from the side, so it's pretty easy.

Difference in material is because you need more rigid elevons?

Exactly. The TPU would be very floppy. I did consider (and still might try it later) having the entire wing TPU with no elevons, but a rigid section (inserted) that the control horn would mount to that allows the wing to just warp in that area. My concern is that there won't be enough travel. We'll see when/if I get around to it.

Have been traveling for a bit and not able to make much progress until recently. It's moving along nicely now.

Looks great Wes! Leading the way with what could be the next big thing.

Hoping you can get enough lead in the nose

Weldon is my local-ish hill. It's not built for left turns! D'oh! :-)
