I have several big sheets of lightweight blue packing foam about 3" thick that I got from work. I happened to think about it yesterday while I was out in my shop. I cut a piece of it to fit perfectly into the fuselage right behind my fuel tank. It works great...keeps my tank from sliding back into the fuselage and it's super lightweight so it's like it's not even there. Thanks for the ideas for fixing this problem.

Glad that you got it fixed. Sounds like you're just about ready to fly!!!!

Yep...If all goes well, it will be in the air for first flight tomorrow afternoon...with an instructor. I can't wait!

Great, have a good time. It's the best feeling in the world!! You'll have a silly smile on your face when you go to work on monday, everybody's going to wonder what you were up to over the weekend!!!

That packing foam is a very useful thing to have lying about.

There are a couple of things that're also very useful along the same lines. People build foamies with insulating foam, the rigid pink or blue sheet foam. I bought a sheet a year or so ago and am still making things with it. Didn't buy it to make foamies, and haven't done one yet, but have almost used it up. Almost every ARF I've assembled since buying the foam has some of it in them, and I've assemble more than a dozen. And it's useful for other things, like airplane stands.

I also bought some furniture cushion foam awhile back. I got the densest I could find. It's still very lightweight for model use. I cut it to fit with some compression. It's in most of my ARF's that had free standing gas tank locations. They provided some sticks to glue around the tanks, and I tossed them in the "to be used later" bin. Cut the cushion foam for slightly oversize bulkheads and wedged 'em in. Got support that absorbs vibration.

Hey, I like the stands. I really need one of those and I have a good bit of that foam left. What kind of glue did you use on the foam to put that together?

I've used a couple of different glues to see what works. Almost anything that doesn't dissolve the foam has worked. I used the last bit of Canopy Glue for one of them. I've also used Elmer's white glue and Elmer's Carpenters Glue.

I've recently found a glue that's sold in the model trains section of the LHS. It is "Foam Tack Glue" and looks just like regular white glue. It gets tacky almost right away if it's smeared out thin. That's good because I can then simply put the pieces together and set the thing aside until the next day.

But almost all of them work. Just stick two parts together and hold with masking tape. Add another part and tape it. Add and tape, etc. Set aside until tomorrow.
