If you had to choose...

A buddy of mine just built a profile out of the 3/4" pink foam from Home Depot (wing, fuselage and tail section). He scaled up a 3DX Foamy so that the wingspan was about 48" and used an OS .46 FX. I was amazed at how well it flew and 3D'd without any airfoil and with the tail as thick as it was. Slow speed hi-alpha flight and harriers were effortless, hovering was simple, loops were tight, but it would fly normal speed straight, level and very stable. He had rounded the leading edges a bit, but otherwise, it was all flat.

So I dropped by the local HD and they gave me a piece of the foam that had been sliced up a bit but was still plenty big enough to build a plane. It's hard to pass up free stuff.

Now I have to come up with a design. Here's the question. If you had to pick a profile plane (based only on the profile shape of wing and fuselage) that would do all or most of the typical 3D maneuvers, which plane design would you choose?

Thanks for your thoughts.

I'm partial to the Sledge....

I had a great time with mine. I've always been interested in the HOTS shape. I've made a bunch of these style of planes, but this one was the best

Q man, I laugh every time I see that. LOVE IT!!!

Do the Sledge

Thanks.

I really want to make another one....I just don't have the time right now. That thing was such a blast....and a total surpise. I did not expect much from it. I knew I was hooked when it locked in a hover and I took the thumbs off the sticks for a short bit. Probably 1 second, but it felt like 15 :lol:

It did the tightest flatspins ever. The only plane I have now that comes close in that department is my Burrito.

I've heard other good things about the Sledge. Any idea where I might find a side and top view drawing of it?

I also wondered about the Burrito. If it was totally profile, would it be called a quesadilla??? I'm not sure if PaulSwany reads this, but if you do, would it be possible to get an overall outline view of the Burrito? I was hoping to get one ready for Tulsa.

Thanks,

Bro, you're putting way to much thought into this. Get a wingspan and a cord, overall lenght and the like, start cutting. Use the TLAR system, it's not gonna be "like" a sledge or Burrito, it'll just be REALLY COOL!!!!

I don't know about the Sledge, but Qucker posted some pictures (top and side) of an Edge that he was working on somewhere in these forums. You might search around and find it somewhere. I'd sure like to see it fly in Tulsa! Is your friend bringing his too?

Here is the latest one. I didn't like it:

Here was the 1st Edge I made. I was bigger and had my MDS 68 on it. It flat spinned nearly as well as the Hots. This edge was way better than the above edge. I've got CAD files with the dimensions if you want it. You could scale it down to a 48 inch span for a 46 motor.

I covered these with sign vinyl. Totally uneccessary...just made them look cool. Added a lot of weight, though.

Fun stuff....and cheap.

Thanks to all. I think I will just "wing" it and see what I can come up with.

Quicker,
Nice planes!! I am inspired. I drew up and cut out mine last night. I thought about covering it with monokote, but saw your website hint about packing tape. I don't think I have enough tape to cover the whole thing. I may try some clear contact paper from Wally World. It comes in a good size roll and should do the same thing. The only thing is that my foam board is pink.... But "real men" can fly pink planes... right?? Did you use epoxy on all of yours or polyurethane (Gorilla) glue? Are you putting the wood dowel rod on top and bottom of the wing? Would carbon fiber rods be of any benefit?
Thanks again.

You don't even have to cover them at all. The foam (blue and pink) is glow safe. Gasoline will eat it up. I'd just put tape over any decals you might be puttiong on it.

As long as you'r flying alone, the pink is OK :lol:

As for the dowels, yep, one on top and one on bottom. I bought a router bit for my dremel and use it to cut the trench. Then I run a line of poly glue (Gorilla or ProBond) and let it set up overnight. I've also use epoxy for this. I think if you use a CF rod you could get by with just 1 on the bottom, but the dowels are so cheap I just use them.

Most of the pieces were glued on with 5 min. epoxy. One thing I learned was the X fuse is the best way to build the bodies. The wood cap I used on the Hots and the yellow edge breaks too easy and doesn't stop flex. The X fuse (like the little electric foamies) is the way to go. The tail was very stiff and did not flex hardly at all. In a violent blender the tail would really twist on the Hots.

Only if it's an ARF, and then only if it 3Ds to beat hell!! :roll:

If you bring a pink plane to Tulsa we may pull a "Swany" on it!! :lol:

If that happens again, I hope somebody gets video.

what's a "Swany"?

maybe i should cover it...

Here it is, and man does it fly nice...
It's 3/4" pink insulation foam from Home Depot.
Specs:
46" span, 18" chord (including ailerons)
42" length (including rudder).
OS .46 FX engine
No particular design, I just took the sheet of foam and cut away everything that didn't look like an airplane.
I've still got some work to do with vinyl stick on stuff, but I wanted to see how if flew first. And it is very stable, harriers are solid, hovering is easy (even for me). It's my favorite for now (until I can get a Burrito).

Good job dude! :rockoncool:

I had a ton of fun with the ones I made.

Now for the obvious question:
How does it fly compared a Burrito with the same engine?

Also which engine on this foamy do you think might fly it like a TTPro-46 flies a Burrito? How does it weigh - compared to a Burrito?

:idea: I think - if you cover it - leave the rudder nekid. That way you can gradually grind it away. Make a few extra to keep in your flight box & tape on a new one when you need it. Then practice until you can post a video grinding a big "9" on the runway! :idea:

I'm looking at that CAD file. I notice you have the servo's & engine & stuff in pretty good detail. Did you draft these yourself - or is there a place where I can download these?

Thanks...
