I've probably covered 50 + airplanes since I've been in the hobby and I've gotten pretty good at it. That said it's pretty hard to explain just using words without writing a book.

I have tried balsa-Rite and a few other film covering pre-treating agents and never found any that were worth the price of the can they were put in, all were pretty much *****.


Ok, to covering, the first step to cover a wing like the enforcer is to sand to at least 320, vacuum the surface with round brush attachment. The brush will help get the dust out of all the crack and crevasses. I then wipe it down with a rag and alcohol. You’ll notice there's still a lot of dust on it even after you vacuum. This is probably the most important part of cover. The covering will not stick to dust, the surface needs to be dust free..

I cover my work surface with 1" foam rubber, this is to keep from damaging the surface while I'm working on it.

When you start covering, do all the small areas first, (patchwork as you call it) the insides verticals of the prop slot, corners. Anything the large sheet isn't going to conform to. Most of this will be done with a small trim iron. You also want to work from back to front this is to all the seams are facing back. You want the prop wash to flow over the seam. If the seam is facing fwd the wash is going to try and lift it.

OK, you now have all the patchwork done, and it's time to do the overall covering. The first question is are you going to be able to cover the entire side of the wing in one sheet, if so great, If not, your going to have to figure out where you want the seems and how there going to blend with your covering design. On a normal wing the seams are in the center and covered by the fuselage. But on the enforcer we want to keep as many of the seams as possible out of the prop wash area, this will keep seams from lifting a fuel from migrating under it. If you have to do it in sections do one section down the middle going from vertical fin to vertical fin.

I am in the process of building a ducted fan version of the enforcer and May do a full write up with pictures as I go.
