Hi Im getting ready to place another order and in it is a Dumas Piper Cub !! rubber band powered.. and its covering is tissue ! Ive never covered with anything but monokote or tower kote and ultra kote.. can anyone tell me roughly how to go about covering with the tissue !! I love building as well as flying and cant wait to learn about covering with tissue !! thanks for any info !!

Well, if it is rubber band powered, you can use clear dope or white/yellow glue thinned down with water to a milk consistancy to stick the paper to the framework. Follow the same sequence of application you would use with Moneycote. You will want to brush a coat or two of the adhesive onto the outside of the area being covered (the wing leading, trailing, tip and center areas for example). If it's silkspan, dampen the tissue in the fold of an old towel which has been moistened (don't make the paper so wet it wants to fall apart!!!), and apply the tissue by placing and gently pulling it over the framework. Although it will shrink as it dries, get as many possible of the wrinkles out while applying the tissue. You will need to add more adhesive to the outside, brushing and wiping it (with your fingers) through the paper and onto the wood. Don't overdo the glue. It is HEAVY, even though most of it is going to evaporate. Depending on how ridged the framwork is, you may have to secure it from warping as the tissue dries and shrinks. You may have to stick down a piece or two when it is dry. The tissue does have a grain, by the way. You will need to tear it to find out which way it runs. Apply tissue with the grain across the top of ribs, for example, so that when it shrinks it doesn't shrink down into the bays between the ribs. P-Nut scale models can be further shrunk by applying alcohol with a cotton ball. A coat or two of thinned clear model airplane dope will help seal things up from moisture. Be sure to do this in a WELL ventilated area! Once again, be careful not to put on the dope (which will shrink the tissue even more) without securing any open framework to prevent warping. Wings and stabs are particularly vulnerable. This sounds like more trouble than it really is. You can always pull off a piece when you don't like the looks of it. (Better to do this while it is still wet!). The covering is cheap. The materials (tissue,glue, water, dope) are cheap, too. Good luck, Dzl

Im looking forward to playing with the walnut size rubber band powered airplane ! we have a indoor fun fly in january at out auditorium.. so this walnut cub will be my first attempt at this !! I have built and covered 11, 40 sized airplanes and assembled one ARF Kit ! so this craft isnt totaly new to me but the tissue is !! tons of thanks my friend !!
