[@bamaverick8740]

[@TheBaldPilot]

Please do!

[@Project2Aero]

Lookin great! One step closer👍

[@TheBaldPilot]

Thanks!

[@99kevin99]

A craftsman at work. Thank you for sharing.

[@TheBaldPilot]

Thank you!

[@leeadams5941]

Once again I am impressed with your skills and thoroughness..excellent work

[@TheBaldPilot]

Thank you very much!

[@macjohnson4326]

Are there any statistics on the performance improvement of the new wingtips? Thanks for making these videos. I quite enjoy them.

[@TheBaldPilot]

No. Mine will be the 1st B Model Bearhawk with the Riblett airfoil using a Hoerner wing tip.

[@macjohnson4326]

@@TheBaldPilot I look forward to seeing what they can do!

[@flyingkub]

Don't rush the end to get things done but I understand the need to get things out so you can move and build the other house.

[@TheBaldPilot]

Good advice!

[@av8ir68]

Wow!!! Great job on your progress on the wings.. I wonder what kind of difference there will be on stall characteristics between the stock wing tips and the new ones you chose.

[@TheBaldPilot]

We shall see! Thanks!

[@scratchbuilder5952]

Great video, can talk a bit about why the tip was short. Is it because the Mylar template does not come to a point at the back end edge? How did things go with carbon concepts

[@TheBaldPilot]

I have no idea why the tip was short. He doesn't communicate very well. I'll just leave it at that.

[@TFlight77]

Love all the videos and will reference them a lot when I finally start my build. Where did you find the tips at? They appear to be carbon fiber as well how did you isolate the aluminum extensions you made to the trailing edge to prevent corrosion?

[@TheBaldPilot]

Thanks! Carbon Concepts in Alaska made the tips. I did not isolate the aluminum from the CF. Although it is coated with 3M Scotch Weld. My thought is even if the aluminum corrodes, it is surrounded by epoxy and polyester filler. We'll see. I may be rebuilding them in a few years...

[@ludwigrieger7556]

Hi Rob, what was the weight per wingtip?

[@TheBaldPilot]

Hi Ludwig. I believe they were 5 pounds per tip, if I recall correctly.

[@ludwigrieger7556]

@@TheBaldPilot thanks Rob, I made mine from 025 aluminum and they are 22’ wide and are about 8 lbs ea. Your aircraft will soon fly and its inspiring to watch your progress

[@Launchie]

Did you buy the Hoerner wingtips? Do they make for the A model? Thanks

[@TheBaldPilot]

Carbon Concepts made these using the mylar from my B model (Riblett) wing. I do not believe they have made these for the A model wing yet.

[@Launchie]

@@TheBaldPilot thank you. Do you have a contract there?

[@TheBaldPilot]

@@Launchie I'm not going to recommend them. Service was terrible. Use at your own risk.

[@Launchie]

@@TheBaldPilot thanks for the heads up. i'll keep looking

[@yasin5300]

How can i analize hoerner wingtip on xflr5?

[@TheBaldPilot]

I do not know. Thanks for watching!

[@letitbe90210]

No spins with horners i heard

[@TheBaldPilot]

I'm not sure. I never tested that! LOL

[@paulslevinsky580]

I don't think you can put styrene based filler over epoxy...but you probably learned that by now.

[@TheBaldPilot]

Yep. Learned that the hard way. Stripped em completely down after making that dumb move...

[@paulslevinsky580]

@@TheBaldPilot haha. I just spent months building a plywood mold with compound curves. Now I'm going to fill the glass/epoxy shell that I took off of it with reinforcing foam.

[@Parr4theCourse]

Nice job on the fillers to make this look “perfect”....

[@TheBaldPilot]

Thank you!
