Imcruz,

In case you haven't noticed, you have ignited the never ending wars between:

Kit vs. Arf
Balsa vs. Spad

Hopefully you can glean what YOU want from all of the ardent posts. I think a few trips out to your local field will be invaluable.

Anyway, I think you mean ARF (almost ready to fly) not RTF (ready to fly), an RTF has the engine and radio gear installed. I don't think there is an LT-40 RTF. The LT-40 ARF comes covered, but you have to finish the wing, flight control surfaces, tail feathers, landing gear, set up the fuel tank, install radio gear, add decals and a few other things. I found this to be plenty of "building" for my tastes (the first time out).

It took me about six weeks to get my LT-40 ARF ready to fly. I probably put from 3 - 10 hours a week in on it. Wife, kids, job, and modeling skills all intruded upon my building time.

I'm currently building a 4*60 kit and I still go pretty slow. I use mostly wood glue because I am still afeared of messing up and like the extra time. I fear CA because balsa is fragile and it sets up too fast for my taste (most of the time). The SIG kits and instructions are good, but I find them somewhat lacking since I am used to computer manuals. The 4* kits plans have many pictures, but they don't always show the step in question and they often reference parts but don't describe them enough for my tastes (so you have to deduce which piece it is). Quibbles, mind you, but something to be aware of.

Also, you, being a misbegotten heathen could be flying tomorrow. Here in Ohio we are still months away from moderately decent flying weather. So you need to ponder what's more important to you, building for a few months or flying in a week or so.

Anyway, have fun.

Tim
