Wood horizontal fins on a scale project
Ok, I will be getting a Century Long Ranger fuse next week. I am not sure what to do with the horizontal fins? They are wood, and I will be painting the fuse myself. What should I do to to protect the wood and keep it from soaking up a lot of paint. Are most of you putting a thin layer of glass over them or maybe just sealing it like a firewall on a plane, with some thinned epoxy??? Any input here would be great.

Your local LHS should sell a product called "sanding sealer" most plank fliers use this. It's like a primer, this will keep the paint from bleeding into the wood, or...get some monokote(plank wing covering) to match the paint job and use it. plus it will be a pain to make sure they are secured when gluing them in place. I have the same fuse, i'm wanting to install lights first, but that is a major undertaking. hope this helps!Smile! people will wonder what you're up to!!

Depending on the width of the horizontal fins you could take a set of crashed 60 sized blades and cut them down to the size you need and use them for your horizontal fins. I've done this a time or two on past scale projects.

On wood you could use the sanding sealer as mentioned in the other post, it works well. I've have good luck with the pre-thinned 20 minute epoxy. After drying I sanded it smooth.

I had wooden horizontal fins and used sanding sealer to great effect, just to mention nav lights I fitted mine by cutting a small groove all the way along the length of the fin and glued the bulb/wire into the groove then it was a simple matter of applying a thin layer of filler to fill the groove and sand it prime and paint it, done properly it's impossible to tell there is a wire running through it.http://www.webstarts.com/micksscalehelicopters

Sanding sealer is a high solids material like primer and clears. I suggest you use something like a lacquer based clear, thinned. One thin wet coat will seal it right up.

Conversely, you can just prime it and sand. The weight is really not an issue for such a small area

Another trick that will work is to coat the wood with Thin CA glue and then sand, recoat as necessary. You will find this will give you a very smooth finish once finely sanded. You can also make fins from Balsa and using the thin CA glue will make the part strong but also keet the fins lite in weight.
