RE: Balsa USA Super Cub Build
Tony,
A method I used to get rid of the brush marks around the tapes was to put some MEK on a rag and very carefully rub the marks into the fabric. When you put on the first spray coat of Poly-Brush the marks shouldn't be visible. This is time consuming but a lot less hassle than sanding. You also mentioned thinning the Poly-Tac, I used a 1:1 ratio of Tac to MEK.
Hope these unsolicited comments help. And it's either Coors Lite or a good single malt on this end

Tony,
I'm having the same problem trying to paint the wings on my cessna. After eliminating several problems ,I thinking the klass-kote epoxy paint is reacting with the Dupli-color high build formula primer. Let me know what was causing the fisheyes on yours when you figure it out.

I fill sure this will solve my problem [link]http://www.autobodytoolmart.com/marson-smoothie-ii-fish-eye-eliminator-20242-p-12968.aspx[/link]. Available at your local autobody supply store. This is for 2 part urethane based paints, I assume it will work on epoxy based also.

I will do as as suggested if I have any brush marks this time around, the photo below is the first attempt after two coats of Poly Spray and wet sand, still can see the marks. I used 1" brushes for the first attempt, I'm going to 3/4" on the second try, and paying more attention, thinning more. Poly Tone paint may have hide the marks, the glossy urethane will just bring out more. Thaks for the suggestions.
Too far east of Rockies here in Western PA, Coors Light must loose it's flavor on the train!

The grommets provided in the kit were 1/16" die cut balsa, since these when out on the curb with the covering I made the replacement units on the lathe from 1/32" plywood. The plywood will finish better than the balsa, the grain still showed through the balsa rings after two coats of Poly Spray and three coats of Poly Brush.
I have included a before and after photo of the both covering jobs, the center photo shows the original work when I used the 1" wide brush, these marks telegraphed through the entire process. The third photo is the most recent. I used 1/2" wide brush turned on the skinny end and just covered the capstrip with Poly Brush, anything that looked like a brush mark was wiped before it dried.
The first wing is ready for stitches, then tapes. The second wing is ready to cover. All in all the second covering job is much better, I'm not at all sad.

Have a question about the scale aileron hinging Tony,At the centre ail/hinge it seems that the brass tube will not clear the jury strut strap on the main spar.Just wondering what you did here if you recall.Or did I miss something?I realize that you build the scale hinging using the Supercub plan and not the J3 plan that came with the aileron kit..
Thanks Steve.
Thanks Steve.

RE: Balsa USA Super Cub Build
Hi Tony...I just had a look at your 1/3 scale Super Cub your building and I'm very impressed especially those great scale details... I'm building one too ( first one was a 1/3 scale J3)...I'm a bit of a scale freak and so far I'm doing quite ok but 2 things I just can't ge done is the fuel cap's and the brake drum's...I even asked some engeneering shop's to do that for me but weren't interested...now I have a question to you, would it be possible to do those to items for me? I pay you for your time and material or whatever it takes...if you can't do it thats fine, all I can do is ask... if you like to contact me, my e-mail addy is.... [email protected]... yes I'm from Western Australia.
Best Regards...Nobby

Hi Tony getting ready to start on same model hope it turns out as nice,
Try appying your take with poly brush and not the poly tac, My dad gave me the advice for covering full scale with stitts it works better, Just brush a little poly on then tape and brush again
Alson I have used 3M77 spray roll your tape out on some cardboard spray it them stick it in place and spray your poly try it on a some scrap

RE: Balsa USA Super Cub Build
I don't know of any, I think it's a one man operation. Is it possible another source for building material has vanished? I posted on another forum that when I can longer purchase materials to build I'm taking up fishing, flying these things is only half the fun.

RE: Balsa USA Super Cub Build
I picked up two rather large boxes from my LHS today. I have been wanting to build one of these for a very long time. The last BUSA was a 1/4 scale J3 Cub in about 1990. I plan on taking a lot of pictures and possibly post them in another thread.........so as not to hi jack Tonys'

RE: Balsa USA Super Cub Build
rv9-a, Congratulations!
That's quite a pile of lumber and stuff in those boxes, isn't it? I'm currently in a very slow process of building one of these too. Been at it for about 3 years, or maybe more. I've lost track of when I started. It's getting pretty close to being ready to start covering. I'm trying to detail the cabin a bit and fit in all the electronics now. Made quite a few changes in the build from pure stock. I'm wanting it to be a "bush plane", but so far have not been able to come up with anything for scale tundra tires.
I will be watching for your thread with interest.

Tony, Rob is in buisness @ Goebel Dash Comp
N1147 River Rd
Columbus,WI 53925
920 623 5053
I'm expecting my dash anyday and at only 25 w/ shipping! I squared up my 1/4 cub today and 1/8 off, I think it will fly straight. I used a similar method of scale hingeing and it worked out great. Thanks for your thread. I built a lithoplate cover in the scale cub battery location and hid my fuel dot, switch and charge port inside, magnet for holddown, no more bending over to plug it in. How we get smarter in our old age. Lanny Khelsea

RE: Balsa USA Super Cub Build
Your right it is a lumber yard. I had no intention of doing anything but looking for the landing gear package. Before I new it everything was out of the box, and no landing gear. So I did an complete inventory and along with the landing gear I found one of the leading edge pieces was also missing. A quick call to BUSA this morning and the missing parts were on the way. [sm=thumbup.gif]
I will assemble the landing gear when the parts arrive but I am going to wait to fall to get started on the actual construction as I need to do some things in the shop and I don't need a 12' airplane in the way.
When I do get started I'll post a link to the new build thread here.
