Default Wing tips on a quicky 500...

Hey all I have a running post on my Zoomer build with a 15% wing and I now need to finish the wing by coming up with some SLEEK wing tips. I would love some suggestion's.

The wing is flat with a full sym 15% wing.

Thanks Dave

I agree, foam would be easiest. Just glue a block on, and sand to shape. Or, you could do the same with balsa, but if you don't hollow it out, it could be heavy. Last option would be to glue on what is known as razor tips. Basically 3/16" thich balsa about 1-1 1/2" wide to the end of wing. Put a couple pieces of try stock top and bottom, and then cover over the tip.

The kit I am building just came with wing cores, a fiberglass fus, and plans. The planes show the tips need to be rounded but I haven't made wing tips before. I think this is done because people who build speed planes like to make things there own way.

I have started to shape some balsa blocks but just seam to sit there looking at it with out any sort of a plan. I had also thought about making some winglets for it. I don't know if that is a good idea. I have been looking at the wingtips of the planes that were entered in the other post about that german speed event and most look to have a fine taper coming from the root of the wing and have a rounded appearence if viewed from the top down (fore to aft).

thanks for the input guys.
Dave

Other than making a new wing.... you're going to have hard time tapering that wing to infinity...

For your average Q500 aircraft just about any tip is fine (if you're not going for all out Q500 competition that is). I'd say use some foam, and make 'em round: easy, simple and light.

This is what I did. I wanted to glass my wing. I had run out of balsa block. So, I stuck a blob of white foam on each tip. I sanded it to shape. I filled it with light spackle and sanded some more. Did this a couple of times until I was satisfied and then glassed the wing. It was no quicker than using balsa but it is lighter.

Here's a couple photos of my wing tips. It's the same as Dave N. stated in his post with 3/16" thick balsa and razor sharp trailing edge glued with balsa triangles. With the 2" taper tips design, it made the plane very table for landing with no tip stall what so ever. Hope this help with some ideas!

Man some of you guys do some REAL nice work.

Thanks again for taking the time and posting the pics. For some of us that are new to speed planes you all are a God send.

Thanks
Dave

Sam,

Thanks for posting a picture of the Razor tips I mentioned above. I checked the inventory, and I didn't have a single Q500 left with that type of tip.

The picture explains it much better than I did.
