Thanks guys, yesterday I went to my hobby shop and saw the sceadu, they come with the 50sx engine and preassembled. Very nice stuff, it´s a big difference beetwen the evo and the shuttle. Fortunately at the hobby shop was one of the top heli pilots here in Chile, and he told me the same thing, go for the sceadu, he also spoke me about the hpm and swm differences and I am going to wait that the SWM kit arrives.
The shuttle has been an excellent trainer, I assembled it, set it and fly it with no help and no trainer lg, just a lot of sim. I never crash it, just made some hard landings. But now is time for a little more.

Thanks everyone.
