Maybe this will help

Hopefully your single center landing gear wheel will be Ok for you at your flying field.

I originally had a single wheel on a Flite Streak. Our CL field is a bit bumpy, and I kept tearing the covering underside of the outer wing on routine landings when the wing tip would drag. I eventually changed it out to 2-wheel gear. I did the same on my new Skyray 35 build. I made up some simple aluminum gear for the Skyray.

Yes.  I thought about it for a while and went with the stock LG.  I can always put a skid on the outer wingtip.  I mostly plan to fly it from grass areas.

What did you finish the fuselage with?  I am using the Ultracote on the wing and as you see, the tail surfaces.

My wing uses Monocote. All the other surfaces are Brodak butyrate dope. I am a rookie builder and can't do 'perfect' finishes. I brushed on the dope color, then a flying buddy of mine let me use his spray equipment for a final clear coat (also dope).

Good job, it looks great Colin.

Thanks Dennis, and it flies great too thanks to a few modifications suggested by Brett Buck. And the OS 25 LA engine doesn't miss a beat.

Make sure you get the leading edge well rounded.

     Good eye, that could use some more work. There is a LE carving template in the kit, it should be AT LEAST as blunt as that. If you lost it, use the plans to make a new one. With a Fox, you are going to need that wing to work as well as it possibly can. Making it more blunt also reduces the criticality of getting it exactly symmetrical.

    BTW, reviewing the plans, I would mildly disagree with Mikey's recommendation of a knife and sanding block to shape the LE.  If you have one, a razor plane or block plane will be a lot easier to control and keep the LE straight. I use the little Master Airscrew plane, or a very small wooden Japanese block plane. I do the majority of the shaping with the plane, taking a series of flat cuts, then just merge them with the sanding block. That will keep you from scooping it out in the middle. Put tape across the ribs just behind it to warn you when you are getting too close.
