I disagree on not needing the hinge machine. When you cut all 17 or so of them you will wish you had it. Heck, even after the first one or two you will be going to get it. And most definitely get the hinge guide. While the knife will work, plan on a few hours with a knife to do them all, while just a few seconds each with the hinge machine.

I do agree that for now leave it a trike gear but go ahead and buy the Dubro main gear and the Fults dual strut nose gear. Using this combo you will get at least 2 more inches of ground clearance and you will be using the main gear later when you convert to a taildragger. The stock gear while good will have you re-bending the nose whell and main gear after every couple of flights, plus after you are solo an APC 12.25X3.75 will really wake that plane up so the ground clearance will be needed.

A 12oz tank will be plenty

The gallon jug the fuel comes in is a great fuel jug. Just buy the Sullivan fuel jug cap or great planes has a kit for about $8.00 where you drill the cap yourself and comes with everything you need minus fuel line

BTW, I did not see fuel line our a fuel pump in your list. To do the fuel jug and a 2 line tank figure on 3 feet, 4 foot would be better as you may cut it wrong plus you need some little pieces (1/4 inch or so) of it to go over all the clevises as a saftey measure plus you need the length to run to/from the jug to the pump, then to the plane to fuel it. A hand crank pump works just fine. An electric pump is for those of use like me that are too lazy to use a hand pump

On that engine 15% nitro with 18% oil will be just fine, 20% oil will be better and yes the APC 11X5 will be a perfect match

Any decent glow driver will work.

On the LT-40 there is no place for a pilot figure as there is no real cockpit, just stickers that make it look like there is one.
