We have decided to start a new company called WingFocus.com to focus on creating flying RC wings. FoilDB will still be here, but will be used for what it was intended for – a database of fins, wings and sails. Even though no work has been done on this database as yet (apart from in my head) It’s a project on to the todo list. Until then, it’s time to keep making wings.
A 90% successful mill. Both sides lined up perfectly. Will just have to make the tabs a little more sturdy next time and change the angles of the wing tips in the material. The trailing edge of the foil is obviously too thin as can be seen in the video, but that was more because of the initial 3D model I made. I’ll probably stick a 2mm thick square trailing edge on it so that it’s a clean cut.
We’ll laminate this one and give it a test fly anyway. Hopefully I can edit the 3D and make the next one in the next few days.
Flew again this afternoon with Zawlade. Probably about a 20kt wind on the cliff tops at Skenners in an easterly. Flew way better with an extra 90g in the nose. The COG must be about right as it powers through turns easily. However the wobbles still happen a ljttle. Personally I think the control arms are a touch springy and the control horns need redoing as they didn’t come together the way I’d hoped. Using plasterboard anchors as control horns is fine for spoilers, but not really for ailerons. I was also a bit too excited to get it in the sky, so they were a tad rushed.
First I’ll make that part of the construction way more rigid and reasses from there. On the up side of the wobble issue, when left to fly straight, the wing stabalises. Also when the control surfaces are under load the wobbles disappear and it flies perfectly.
