Title: Covering a model with silkspan
Post by: Dan Labine on July 19, 2006, 06:20:33 AM

I am building my first CL model, a  Sig Akromaster, and since I always used iron on films with my RC planes I am wondering if I use the silkspan to cover the fuselage and stab or just use dope to seal the wood.

So the silkspan is for filling the grain of the wood and may add some strength. I don't expect the Akromaster to survive very long so I'll probably just omit the tissue. Thanks for your help.

The silkspan adds LOTS of strength to the wood, believe it or not.  It helps fill the grain, but adds strength by holding the grain together.

Hope this helps,

Ron

On wood surface, I stick silkspan down around the edges, then water shrink it, then stick it down with thinner.  This gives a smoother surface than just putting it down with thinner.  Do not do this on a 1/8 thick stab, however, as the watershrinking may well give you a warp.  Been there, done that.
