Power is a Fox 36, built up by Mark Smith in about 1992. It started as a typical 1/2" crank sport Fox 36. It has a slightly bored Fox factory reverse crank, a Mark Smith/Willy Wiley ABC setup and button, and whatever else Mark did to it. It has my own carb conversion to accept an OS 4B carb. It's basically a small crank slow combat engine. For years I ran it on 50%, now I am using Powermaster 20/20.

 Well, I don't know where it will fall into the "Build List", but I scored a NIB Dumas Crusader kit on Ebay last night for 46 bucks! (PE**)

I considered bidding on it, but if I needed another one I'd scratch build it. Here's a wild idea. Build it for carrier as a conventional 2 line plane with a 2.4 ghz radio operated throttle. You can buy a 2.4 ghz car radio for a lot less than a Brodak handle and bellcrank, and avoid unfamiliar and admittedly sometimes troublesome technology. Plus, if you don't like using the throttle, you can fly without it. If you don't like the carrier idea, take the hook off and shoot gazillions of touch and go's. How can you go wrong?

AHA, so you were the guy that outbid me. Great, at least it's some one worthy.  H^^ D>K y1 LL~ LL~

 Jeez Ty, now I feel kinda guilty. Thanks for the compliment though. At least you can be sure it will end up in Navy colors!

 I'm not sure how I'll approach the project whenever it comes up. I don't fly Carrier so I was just thinking it would be a neat sport flier, but who knows? I REALLY like the way Bill's came out in this post. If I could possibly duplicate that, I'd be very happy. y1

Wayne and Ty, the one structural mod I would heartily recommend is to put some bracing between the top and bottom rib slices after the wing is built. The ribs have no compressive strength and break very easily!

 Thanks for the info on that Bill. I almost always add shear webs anyway, it adds a lot of strength and I also think it helps keep the wing straight through the rest of the building and finishing process.

 Do you have any pics of yours at that stage?

All the pic's are earlier in this thread. Reply #21 and #28 show the ribs pretty well. I didn't brace the ribs, and several of them are already cracked. >:(

 Thanks Bill. I can see that I'm going to have to scour this thread whenever I get going on mine. Looks like I'll be making some jigs too.

Are you going with the I-Beam ribs or are you going to cut new solid ribs? H^^

I'm going with the I beam ribs. Why change them?  I like I beam wings. They are quick to build. D>K

 I've never done one, any potential time saved will be lost to head scratching. :)

I-beam is not that hard to do and sometimes I think is faster than a regular wing.   H^^

Hi Doc,

I agree an will say that "construction" is quicker than about any other type of building.  It is cutting the ribs that takes time but I do that at night while sitting with the wife watching TV.  I don't have a clue as to why some people balk at doing an I-Beam build.  Nothing could be simpler!

I think the drawback is the jig for making ribs.  I adjusted mine several times before I was confortable cutting ribs.  Tom Morris' book is what helped me a lot.   I also edge glue sheets together to make ribs.  Amazing how many ribs can be cut from one sheet of wood.  But, then again it takes two peices to make one rib.  By the way the edge glued ribs are used for making the half ribs. H^^

Finally got to see this plane in action at the Tulsa meet.   Bill makes it looks so easy flying carrier.   The plane looks even better in person.  Also I need to start listening and doing what the  man  says. H^^
