The LT-40 is about $400.00 which comes with everything:

Aircraft (Offcourse), Servos, Engine and Radio.

The $20 bucks you are talking about, what does this include. And physically what is the differance between this and the LT-40.

I've just heard great things on the LT-40 and I have never heard anything on this SPAD thing.

By the way, their website looks like my kid made it. sorry, I am like that; if I don't like a website, I wont waste my time on checking it out.
