spackle????


I have been looking around on youtube and have seen where some guys building foamies are using spackle to smooth out or shape their planes, is this the same spackle as they use in drywall?????

No, there is lightweight spackle you can buy. It's usually sold with the other stuff, but the container will feel empty when you pick it up. I use it all the time on my foamies, it works really well and sands smooth once dry.

Spackle rocks? Why would I want to attach rocks to my aircraft? Aren't rocks kinds heavy? [cough]

The idea is to get the foam as smooth as you can first, then apply Spackle as a last surface smoother. Kinda like Bondo for cars, but without so much rust involved.

Some builders are also mixing the light weight spackle with WBPU or Polycrilic to make a coating that can be brushed on, then sanded after it dries.

I use the lightweight spackle all the time. This is not the drywall spackle that is like joint compound. Lightweight spackle is almost weightless. Once it dries I doubt that it weighs much if any more than foam the same size.

I use hobby-lite. I bought it then figured out it is the same as the Elmer's dry filler I had. When the hobby lite runs out I will use the Elmer's or dap filler, it's about $3 a can cheaper.

I've use Spackle for some of my larger aircraft. The trick is to make sure to sand most of it off. Leave just enough to cover dents and holes or whatever. It still adds weight.

Bill, I was trying to make a phunny. Obviously my phunny skills are not even up to my flying skills, which aren't all that great to begin with...just take a look at my collection of damaged and wrecked 3D planes. Heh.

Hey, maybe some Spackle on those 3D planes, and...

Sorry about that, my bad. Shows how little I know. When I first read about using skackle, I thought they were talking about the heavy stuff.
That was a few years ago.

Good Info....

Will have to give this a try on the left sponson of my Flying W - damaged in a bone-head maneuver trying to fly through a "tunnel" - made it the first time, second time "not so good"

Thanks

Also, you can shape and then sand the dry spackle and then hit it with foam safe CA and it becomes rock hard at no added weight.
