Default Carden Profile

Since I've scrapped the idea of using my crashed Wildhare Extra, I've been searching for a new scratch build project. A local guy makes foam wings and also sells wing tubes. I went to get a tube off him and was thumbing though his book of available cores and I found he has wing, fin/rudder, and stab/elevator cores for the Carden 40% Edge 540 and Extra! Each wing panel has a span of a little over 50" and he said that the wing area is bit over 2,000. The fuse must be pretty wide on the Carden 40% because the wingspan on them is 114" to 118," I think. What I like about using these cores are the facts that Cardens are known to be excellent fliers and I would have a tapered wing, which is alot of work to cut each rib by hand. There is still a bunch of work to get the wings ready, but looks to be fun. I'm going to put a link here to a Carden build I've been following, that way you guys can see how the wings get put together.

Edit. Here's the link. It'll take you to the first page, where he starts sheeting the stab at the bottom of the page.

Thanks Jeff. I still have to get some measurements and stuff. I need to figure out where to put the firewall, wing, and stab.

I'm trying to think of how I'm going to make the fuse. i might use the Ultimate plans as a guide, but I will legthen it some, plus add a cowl induction hood to it. I might use thicker foam also with two carbon rectangles down each side.

Here's a quick drawing of the fuse with the cowl induction and the color scheme.

You're not wasting anytime at all! Where did you scrounge them plans? I think I'm going to stick with a foam fuse. It's pretty easy to do. I think I'm going with a two inch thickness though. Going to check the weight of the foam first.

Found it on this site "www.profili2.com" on airobatic page 10, tons of plans on this site. I use Delta Cad to resize and print plans.

Well Bigg, another change in plans. I went to Dynamic Balsa today and ended up getting the 80" Extra 260 foam wings. Need to take about 4 inches off the ends to get them where I need them. Brian gave me a junk foam core to practice on !!!!

Are you going to just use them wings with the other fuse? I haven't did anything yet. My biggest hurdle is making the hole for the wing tube. I'm going to use a wire in my soldering iron to do this. I'll wrap it around the aluminum tube that way it'll be the right size for the socket. Brian told me how he does it but it seems like alot more work.

Yes I will use them with the fuse I'm building. I'm not sure how I will do the tube, probably do the grove and ply spar method that he told me about. I'll jump that hurdle when I get to it!!

Put the wing on the back burner until I get mine done and we'll do yours the same way if you want. Click on the link in post #1 of this thread. You'll see exactly how it's done.

I was looking at that last night . He makes it look easy enough, but his wing tube holes are already cut ...Brain said somthing about plugging your gun into a dimmer switch to regulate the voltage , don't want the small wire getting super hot...

Cool. The more I look at these core's I don't think they are going to work for the plane I'm building. When we mesured them I told him rib one was 19+ ". These cores are close but that doesn't take into account that I have to cut the control surface from the wing, this plan has a 19"+ rib 1 with a 4 1/2" control surface for 3d , not enough wing on this core...I need a set of cores that call for adding trailing edge and building additional control surface for it.

Think I will start building the fuse and worry about it later . If anything I'll take the mesurements and see if he can cut me some or find a set that will work better . Either way Im going to keep these....

you'll need 35% Extra wings. I think I seen some there. If not, I know he's has the 40% ones.

Got a little more work done on the fuse. Ran out of 1/8x2" balsa. This thing seems pretty solid. If I can get the wood at the LHS I should be able to move along on this fuse.
