Welcome to the forums, the FT-22 is a great plane, I have built about 4 different versions of this plane and loved everyone of them.Hi Guys,
New to the RC scene and also scratch builds, I’m currently building an f22, plans from FT.
How can I cover the edges where foam is exposed to give a neater finish? im looking to spray the plane with acrylic, is this suitable? thanks
Yea there is another video on my channel of how to prep the plane for paint using oil based polyurethane. It seals the paper to make it waterproof and is a lot easier to paint, and it all can be done after the plane is built. Link is here. Ever since I found out about this I have been doing it to my planes and will take any kind of paint over top@Hai-Lee thanks for that advice!! 👍🏼
Paint needs to be acrylic right? Otherwise melts the foam?
I’ve been using something and can take a photo of it when I get home.@BATTLEAXE we don’t have minwax over here in England, looking at the characteristics of the minwax, an oil based wood varnish would be suitable?
Anyone from outside the US got any recommendations for something comparable to minwax?
Its mostly the solvent and propellant in the paint or glue that eats foam. One trick is to hold the rattle can 18 inches or so away from the foam, this gives time for the nastiest to evaporate.....Paint needs to be acrylic right? Otherwise melts the foam?
Yes any oil based polyurethane will do@BATTLEAXE we don’t have minwax over here in England, looking at the characteristics of the minwax, an oil based wood varnish would be suitable?

Great advice. Whenever I plug in the hot glue gun I plug in the iron. Those lumpy blobs of hot glue are ugly. I go back over almost every hot glue seam I make with a hot iron to smooth it out. Use a hot iron instead of a foam scrap to smooth out glue fillets. Use a hot iron when spreading the hot glue on hinge bevels to smooth it out and make it nice and thin. Use the iron to flatten out those A and B folds that didn't quite close up before the glue set.You can iron the edges of the F22 after its built. I did. You have access to most of them and its now standard practice for me. In fact, you can iron anything you see. Got an edge sticking out with a little too much hot glue?....iron it.
Is that the stuff you put on with a caulking gun? What does it look like before painting? Does it makes the edges smooth? A photo will help.I close open ends of foam board with Power Grab.
Power Grab is made by Loctite. It is an adhesive and it does come in caulking gun tubes or in smaller squeeze tubes. It is white but you can mix in some acrylic paint for color. It can be cleaned up with water before drying. I also use it for laminating foam board as it give you working time not so with hot glue. You can smooth it with a art spatula, or with a damp cloth or paper towel. After drying its kind of like a hard rubber so not so good for sanding smooth. You can also use for mounting things like ESC's, servos. etc. Great product to have in your shopIs that the stuff you put on with a caulking gun? What does it look like before painting?
