Hey Farmbuyer Welcome aboard

Glad to see your having fun. You really don't need the aluminum two layers of 1/8" cut to fit and epoxied will work quite well. same with the wing dowels. Also including a site which explains the pull - pull Http://www.member.cox.net/bdfelice/

I've done this on the rudder and tail wheel on an lt-40 myself and it works well. I kind of did my tailwheel as an afterthought and ran it off the rudder but both can be run off of the same servo, I also suggest that when you hook your cable to the tail wheel that you put a spring on both sides at the tailwheel to absorb shocks from rough ground.

As far as the ailerons go you had plenty to start with I barn doored mine at half length I still had more than needed. The flaps are gonna be fun I don't think you'll ever get it to land.

On your wing at the trailing edge where your going to put your hole for your wing bolts you will want a layer of 1/8 Ply to add a little strength over any portion of the hollow rib area and to protect the soft balsa trailing edge. also on the inside and outside where your are going to fasten your landing gear I recommend a 1/8 " piece of ply big enough to over lap your gear by at least 1/4" fore and aft. and full width of the fuse on the inside and outside of the fuse for extra support the fuse in this area is only 1/8" to start with and dosen't take a lot to rip it out on a rough landing.

The bombbay doors should be fairly close to the cg depending on how big you plan on making them and what you plan to drop. You should be able to hook these up to operate from one servo again depending on choice of control horns and such.

Keep us posted on your progress I love these lt-40s. Trying to decide right now on bashing an lt-40 or 4* to a twin for the experience and to break in the engines for my p-38 project.
