Hoerner Wing Tips

[Nrtabor5]

I'm just getting started with sourcing parts & materials and I was wondering if anyone has had luck with any of the commercial Hoerner wingtip options?

I have fiberglass experience from some boat builds and the writeups in the forum seem pretty straightforward. MSwain's seems to be very easy to follow.
Unfortunately, based on my previous experience I also know that custom fiberglass work has a tendency to blow up in time and expectations; there's always JUST ONE MORE sand/glass layer to remove just a few more pinholes. If there's a prefab option that gets us 90% there and I'm just fairing in some length (Caldwell style) and adding light pads then I'd be very interested.

Any recommendations or possible sources would be appreciated!

Randy at Carbon Concepts in Alaska is doing a good job with these. Not cheap but good quality work according to all who have used them. Mark

There’s a company in the Ukraine that builds composite aircraft parts. I came across them through the Cessna Cardinal group. Maxim is the guy I emailed with and he seems pretty well liked among the Cardinal folks and his parts look good in the pictures people post.

I was working on a CAD drawing to send him so he could give me a quote for tips but I got bogged down and haven’t finished it. The Ukraine is a long ways away but supposedly his pricing is good and the shipping is reasonable. I haven’t found anyone else that will make them, yet.

The Carbon Concept tips seem to be a reasonable option. IMO, they are pretty far from the ideal Hoerner shape but they probably get you most of the way there.

Thanks, I'll reach out to Carbon Concepts and see what they can do.

whee Do you have the company name? Some google searching did not yield any promising results

I find their web site to be very lacking in information about what they offer.

When dealing with Alaskan companies you learn to be patient and come to grips with “Alaskan time”. If it’s hunting season they aren’t in the shop. If they have a hobby or new interest they may not be in the shop. If you didn’t say you needed it yesterday they may not be working on it.

I’ve purchased from Randy and have more coming. The tips I ordered sometime last spring he knew I didn’t need right off so… well, now they are shipping. Lol. No biggie, just a different style of business.

I just don’t see myself investing in Horner style wingtips…. But I will ask the question, how much performance improvement do they bring?

I seem to be seeing about 2 kts less at the low end. That was measured at the stall and also today flying circuits.

Fork 2 knots/3mph I just don’t seem myself doing it. You guys just have more innovation in you than me. I just want to get my plane in the air asap. Plus adding wingspan could possibly hamper my space in the not yet built T-Hanger I hope to have in 11 months

I agree - get it flying first. One day if you want a wee side project .....there's plenty.
