Surface finishing
Couple of questions first....
1) Is there open framework? How will it be covered?
2) What types of paint are available to you?
3) Is there a Hobby Shop nearby?
4) Where are you located?
I have no knowledge of the plane you are building, therefore I need some info. in order to better answer your question.

Also In the same boat, except mine is a standard balsa sheeting - wondering if a sandable wood sealer is enough to use before primer. Also contol surfaces would be done in silkspan to look authentic. any hints sugggestions. TF 190d kit.

The first questioner needs to supply more info.
Dgreve:
I strongly do not recommend just using a sealer then primer. The grain will probably still show through no matter what filler you use. But, most importantly, the strength will suffer significantly. You can use silk, Koverall, fiberglass, plastic film, silkspan or what ever else appeals to you but do use something!

If you don't need to add structural strength with the finishing... go with medium or light silkspan. The silkspan grain fills and seals easier than the balsa, and you end up saving weight vs using sanding sealer on the balsa. (you can apply enough dope sanding sealer directly to balsa that the grain dissapears.. takes a LOT of coats and a lot of sanding.)
If you need to add strength, you can go with light fiberglassing, or with light silk. I like the silk (most times...) you can apply it with yellow glue mixed with water, and come out lighter than by using the lightest fibeglass and epoxy finishing resin. You can also apply silk with epoxy or polyester finishing resin or water based polyurethane paint. The silk grain is usually much finer than the same weight of fiberglass, so less filling is needed. (again saving weight)

Thanks for the info. I've been debating now about the fiberglass - I imagine that would add more strength and not ding as easy as the silkspan, but as said, would add weight. I haven't even started the kit yet, so still plenty of time to decide. Thx for the info [img]i/expressions/face-icon-small-smile.gif[/img]
