I bought a lt 40 partial plane.. it is all put together, except does not have horns on the rudder or ailerions, i need those and fuel tank and the hardware..and a motor mount.could someone give me some advice on what i need and where i should look?
plus what would be a good motor on it? I am a beginner and want to finish this plane.. thanks in advance, jim

A .40~.46 two-stroke, a .50~.60 four-stroke. I had 13 or 14 engines on mine, I liked the OS LA.40 and the Saito .50 the best. The airplane is a great flying plane with that power, with more power it's just your average plane.

DuBro makes the horns and aileron hardware you'll need.

You will need the control horns, pushrods, and clevises. Any standard size will do.
If it is not covered yet you will need a good film covering, heatgun, iron, etc etc.

A .46 size engine would be perfect, with any standard .40-.46 size nylon mount, with a 10 -12 oz tank and I love the Futaba radio systems. Any standard size servo will work.

towerhobbies is a great place to get everything you need, I love'em

If you can visit a local hobby shop, they can help you with the hardware.  Note that Sig is well known for producing hardware like control horns  I flew mine with an old used Saito 52 4 stroke which was perfect.  Remember you will spend a lot of time cruising around at about 1/3 throttle.  So you need a smooth engine not a hot rod.

Great plane and easy to fly and train on.  You should do well.

Don't be afraid to call Sig Mfg. either. I have built two of their kits in the past year and have needed extra parts at times. If you don't have the plans, you may want to order them. It will really help you see where things go and how they go together. Sig has always been helpful to me over the past year and a half. I even call them sometimes to just get building advice.

I have the LT-40 and have flown it for the last year. It is a great plane to start with. I have an OS LA 40 engine. It has been reliable and a good match for beginner ability and the plane.

Also, look up the "Pay It Forward" build post by RCKen on this site.It was unbelievably helpful to me when Ibuilt my LT-40.

Good luck with it!

For a manual - follow "the yellow brick road"

Only comment about your engine choices - avoid over powering the LT as it's a trainer and is sensitive to throttle settings. Straight-n-level at 25 - 30% is easy.
