Here's a trick I heard about: spray a very light coat of black on the uncovered wings, then use transparent covering, it really pops the structure out.

Yours, Greg

Thanks Greg-

That was kinda the original plan, but I think it's going in a different direction now. the wings are going to look a bit worse once the carbon tow is in place. It'll be smoother, and stronger than it is now, but it'll show the black stripes of the tow. The black would have to be opaque for the effect to … Ehem.. Take effect. ha ha.
We also can do what I did with the black covering……...

You can't see it in my original photo, but the transparent orange and white hobie has had numerous wing repairs. The fix I used was to very lightly spray the repaired wings with a light brown the same colour as the plywood. Once the covering is over the top you can't tell the difference. With a bit of work it can look like a brand new wing!

Has anyone ever glassed the wood on the wings? I have 2 sets of wings with multiple repairs on each panel. I'm thinking I should glass them with 3oz to strengthen them. Epoxy or resin? Or maybe polyurethane or polycrylic? Anyone?

These repairs were glassed with resin, what appears to be years ago- while lumpy, they functioned well- appears so at least... You're just making the compromised section as strong as the existing skin...

I'd think the glass would not work well with the iron on coverings..?

Any suggestions on what to use; epoxy, resin, or polycrylic?
I'd imagine poly would come out lightest, or do I need more strength?

I think monokote would work fine on glass, wouldn't it?

Thats what I'm using! I hope it works!!

I figure i'll overlap at least 3/8" as typical at the leading and trailing edges, also where the trans meets the opaque. Then I essentially have a bag around the wing to shrink down. Also, the heat from shrinking (obv) activates the adhesive so we'll be all good.
For a friend a while ago I covered a set of spats and a cowl for a ryan STA with chrome monokote with pretty bitchin results so I know it'll go over the glass….

Nice looking spats. Should've gotten chrome monokote last LHS visit! How did you get all the compound curves?

I thought the pics showed a touch more detail, but I just cut "panel lines" into the areas that stuck without wrinkles, then overlapped with the next piece... Of course, bottom to top, back to front- still stuck that I know of, and it's been about 3 years.....

Hey Wayne, the places we use to fly with Hobie are all gone, strands in Dana Point turned into a big housing project that has failed but they flattened the hill and Salt Creek which is now the site of the falling off the cliff Ritz Carlton both places were never legal to fly at and constantly had to hack up the fence to crawl through just to fly, the police would show up every now and then and tell us to leave but that was it.

check out this Hobie Hawk commercial he's flying at Salt Creek

Well, since Lewis made a post on this thread just over a year ago,....

....I figured it was safe to post a resurrection post, to aid in the restoration of my Hobie Hawk.

My Hobie wings and tail are done in Red and at some point the white fuslegae was also splashed in Red. I'd like to restore the fuselage to original white and thought I'd ask what the preferred technique is for stripping off paint from this multi-material fuselage.

Thx

The forward part of the fuse is pretty tough, so you can use alittle stronger sandpaper, say 120 or 220. The boom is very thin, unless it has been repaired, so use lighter sand paper like 320. You can use a stripper, but with all the old materials, it would be a gamble with possible distortion from the chemicals, and I'd recommend against it. The tail section is made of a clear plastic, not sure what, and is probably pretty brittle, so go very easy on it with sandpaper. Good luck and post pics, please.
