3) Battery location, I've seen three different methods. The 1600 I intend to use is a bit longer than the equal 3 cell but about the same weight...I know C/G is critical...and the 7.4v has worked well in combination with the brushed motor/prop mentioned.
4) Air surface control horizontal stabilizer and rudder (hinges, tape or combination of epoxy & rods..
5) Push rods, stock or customized..?
6) Clevis and control horns, stock or custom...?
7) Do the stock wing strut supports (rudder included) do the job or will additional wire support or enhanced struts be advised (several different methods are shown on the threads)
Pizzano, FWIW my original Tiger Moth is pretty much bone stock and flies just fine.
1) Not needed, no. I eventually put the wing spar from a Stryker in my lower wing because I noticed the wings flexing a lot during extreme maneuvers. Nothing ever broke or came close to breaking and I wouldn't have noticed it at all if I wasn't doing onboard video. I've also added flying wires, but mainly for the look of it.
2) I used the stock single aileron setup on my first Moth. It's never given me a bit of trouble. (I'm only running 2 ailerons.) On my second Moth, I went with dual aileron servos because A) I'm more comfortable with the idea of chopping holes in my wings than I was 2 years ago and B) Things get pretty cramped inside the fuselage and this way gives you more room in there.
3) My batteries both slide right down into the nose, in the more-or-less stock position. My second Moth came out pretty tail heavy - I think because of my heavy paint job - so I modded the battery compartment to allow the battery to slide forward more than stock.
4) If I understand the question, I used the stock Tyvek hinges on my first Moth (they don't make those anymore, but I actually prefer them). I used the stock nylon hinges on my second moth.
5 & 6) I'm running all the stock equipment on both of mine. My first Moth has been flying since November of 2010 with all stock bits.
7) Again, I've been running all stock parts on my first moth since 2010. On my second Moth, I made new wooden interplane struts but mainly cuz I wanted to. The originals haven't given me any trouble.
As to landing gear, my first Moth was modded with an extra set of gear wire mounted to a wood brace on the bottom of the firewall. This has proven so strong that a bad landing which catches the gear will snap the fuse it two, rather than breaking the LG. So ... partial success?
I have no good photos of the setup.
Me new Moth uses a second set of wire mounted behind
the original mount point. I carved out a rough slot behind the original, used the second mount that comes on the part tree.
The bottom line is, in my experience, if you just build the stock kit, it'll fly just fine for years.
