SO I gotta say first thing up - mixed feeling on the FT brown board. The waxiness is nice for not worrying about waterproofing with poly, but has now irked me a bit. (well, painting it sucked too - I guess i didn't sand it enough with steel wool and the paint peeled easily)
I'm FINALLY back to building something after quite the break. Putting together another mini zero after my previous one met its demise in combat at FF'22 - yea it's been that long. I decided to go all out with @burkeomatic and his work of using tite bond instead of hot glue to save weight. Probably easily 25+ grams on this tiny plane (weighed in at 24g per stick). I had some brown FF board laying around so I figured why not. I glued a few parts up last night but did a few test joints as well just to be sure things held up well. Note that I did not use steel wool to take off the waxy coating (which apparently I should have). Where the foam attached to the peeled back of the paper it seems to have held quite well (think A and B folds). But where the foam attached to the outer face of the board (again, the butt joint of the same folds) it popped off very easily. I just 'sanded' the faces again and re-glued things and we'll see how they hold up when they've had a chance to dry overnight.

I haven't had a good experience using titebond and the brown stuff. I think you need to hot glue it or prep the surfaces. I build a SBK like that and it didn't work out well for me at all. |

I guess I'm lucky only the white stuff is available in my area.

I guess I'm lucky only the white stuff is available in my area. You have to order the greasy brown stuff from FT. It has it's uses. If I were building a plane that I flew in the wet or snow, I would 100% use it. If I lived in S. Florida, I would 100% use it. It just isn't as builder friendly as the white stuff. Honestly, the black is the best, because it is harder to peel the paper off. Unless you want to peel the paper off of course. |
