Foamy Season is here - Milling Depron Foam -> A How To

	Tried that once. Made it too brittle. Wasn't trying to make it light though. It was .5oz cloth.

Craig, you gotta use the 6oz cloth on the 9mm depron to keep the stiffness up and give it strength. Also helps with penetration. Those airconditioner vents really put out a blast of air!!

You guys think im Joking....

Looks like a great system! I'd try milling more area/depth though. In my experience, I've removed at least 40 to 45% of the foam weight.

Wayne, I thought for a moment that your were going to cut your BigAss Foamie up into a couple little 26" foamies. This is a DWFoamie 24" YAK Junior that is 3.4 AUW lying on our 55" YAK.

LOL.
No. I'm not gonna cut that one up. Its too much fun.

Funny you should mention that... the AC was on high last weekend at the gym, and my airplanes were crabbing. I was actually doing stationary rollers in front of one of the air vents...

Great tech tips, I will be giving this a go for my next bird... Thanks !!!

Will eventually use this on my birds, if I cant get it CNC cut . . . Looks cool, and saves weight! Any differences flying wise other than lighter? Not sure if the edges would disturb the air or not . . . I would assume not . . .

Thanks for the tips!

Seth, I'm sure there is a small drag effect from the resulting shape of the skin, however its very small..... You know the benefits of lower wingloadings, it can be worth it....

Its funny, last year, I had by far the lightest airplanes in competition (I flew one 3oz airplane at one point during foamy season last year), however I never milled any of my airplanes last year.

This year, I have my milling setup down, a new ESC that weighs half of last year's, New motors which are lighter, you name it, this year light will be right!

Yo jeremy, you better make it to the Great planes E-Fest in a few months!
I want to see your work up close!

[Matchless]

Jared, I'm planning on going to it this season. I'd like to get a closer look at your builds as well (did not get to see your foamy up close at the St. Louis Huckfest)

This morning, I went ahead and cut a new horiz/ele for this prototype and milled it with a slightly improved template-opened up the cuts a bit to compensate better for the bit offset. I also increased the depth of cut a few thousands. I'm pleased with the results.... No need to re-cut this one!

hey, matchless, i think i remeber u, were you the one that leseberg flew the plane with the transmitter upside down in the hotel. i may be wrong, im not sure.
