I think all is working again now. Please leave a comment on a photo somewhere if something you need is not working still.

Thanks so much for sll the info! Maybe its the humidity? I was doing it the garage with the door slightly open to let out the smell. Plus after you apply the sig nitrate just to seal the balsa before actual covering how long do you let it dry? Maybe that was my issue too. Still turned good, just had to hold it a couple times to let things dry.

I use Sig nitrate dope. "It is intended for use as an initial surface preparation only...controlled shrinkage...better adhesion...higher solid content than butyrate for faster filling". I used AeroGloss butyrate for covering for years but I switched when I realized that nitrate does provide better adhesion of silkspan to balsa. I tend to believe the other things the label says about the product, as well. Open framework areas often need several applications of dope around the edges when initially covering. Sometimes I have to physically hold a piece in place long enough for it to adhere. Temperature makes a lot of difference when using dope and covering wet and the relative humidity has an even greater effect. Here in southern Arizona the humidity is usually very low, sometimes single digit %, and it's usually fairly warm. That makes wet covering open framework outside rather tricky because the dope dries before the silkspan is securely in place. For open framework, I go to my room, open the window, shut the door, and do the covering. Once I'm sure it's in place, I turn on the fan and leave. When the silkspan has dried, about 10 minutes, I take the covered piece outside and paint on another coat of dope and leave it outside until the odor finally goes away. Usually after sanding and trimming away the silkspan, there will be areas that did not fully adhere so I use Testors wood cement to glue them down and a bead of it around the edges to make sure they are sealed. When it's all dry, a light sanding of the edges will blend it all in.

Hey DD... What brand, and kinds of dope, or dopes do you use? I have Sig nitrate, and Areo butyrate and cant seem to pick which one is better for the intial adhesive to the open area framework on my models. This plane was done in the Sig Nitrate and had some moments where I couldnt get it to stick. Thanks

All is doped, though I might add another coat, then start painting.

Close up of the cooling slots.

Finished adding the horizontal, and verticals, and faired them in the best I could. I also added the cooling slots in the front. Everything is ready, and will be painting soon.

LG's ready. 3/32 and 5/32 styrene tubes, and masking tape. Then painted.

Doped, next up silkspan covering.

All parts doped, and ready for silkspan.

Excellent work ! For the fillets I just use the M1 parts and then attack them with Microfill or Hobbylite to give a smoothed off appearance.

Man, Really need to make sure this FW-190 comes out on point! Some serious builders putting the pressure on me. And thank you so much for the kind words, and help too! Speaking of, What order would you put on your fairings, and the included M1 fillets? Which one first, fairing, or fillet? Not sure if Im gonna use cardstock, or paper then fill them with filler...

It's coming along nicely, good job!

I would say you're an excellent student.

Thanks! Means alot, Its my first, and I have been studying like a fool of all the great builds on here!

Good job!
jace314, Comment for image # 2336502 Aug 11 20:31
Thanks for the replys. So cover it first with the silkspan, then add a panel with some thin styrene, or card stock, then paint? Should I try to lighten up the edges of the panels so the lines are not that pronounced when painted? Got any examples in any of your builds you can point me to?

You're doing a terrific job - well done !
David Duckett, Comment for image # 2336502 Aug 11 19:23
Modesty prohibits my use of the euphemism "great" to describe my builds, at least in public ;-), but I would cover it first. It's looking fine!
