This perplexes me a little bit.  On a profile plan it will show a pattern to bend the landing gear wire that is one piece. Then it shows the typical installation with a hole in front of the leading edge and straps on the side. This is fine except how do you get the bent gear into the hole? Is there something I'm missing here?

As stated above , one way is put the gear onto the body first, then install the wing.  The downside is that the gear is in the way for painting and sanding.

Another way is to make the hole a little oversize, then install the gear and fill it in after the plane is covered and painted.  If the extra clearance is in the form of a slot that parallels the thrust line (between the engine mounts), it won't really weaken the plane.

If you move the gear just a little bit forward, drill a 3/8 hole through the fuselage, and cut the gear in half.  OK, now you take a piece of 3/8 aluminum rod, drill a 1/8 hole all the way through.  Epoxy this rod into the fuselage. You will have to make a grove at the bottom to accept the bent LG wire.  You can do all of your fuselage finishing and when you bolt the gear on it will not twist around.  This works very well for airplanes such as the Sig Twister. 

I really like your idea, Phil.  It also allows you to reposition the gear if necessary.  

Gear mounted to bottom. nice part is you can put extra inserts in the bottom and move the gear to where it works best. I put a piece of 1/16 rubber sheet between the fuse and the gear so I don't have a metal to wood contact.

My last profile, the gear was two legs. In this case carbon fiber ones that I laid up myself. 3 bolts went through the fuse to hold it on. Worked pretty slick. I'd show a picture but unfortunately, I lost a hard drive with all my pictures. Sigh...

Randy's "Ringmaster Deluxe" CF landing gear. Pretty fancy. How much did the bare legs weigh?  Steve

I have been sing this type gear on profiles for a long time.  It doesn't come loose.

Almost any way but the way the stock Ringmaster/Sterling/Goldberg kits do it is better.  Building the gear into the plane before it is painted is just nuts.  And it always wicks oil into the fuse/wing joint, and sooner(never later) starts looking scuzzy.

One other point, adding a spreader bar as in the picture above does wonders for stiffening the gear and makes for much better landings.  Oftentimes you can go one size smaller on the wire and it still will be stiff enough.
