I think the Trex is a great heli. I fly all the time with a guy who has one. Its simply in a different league than my BCPP. Completely awesome! But it runs out of room indoors quickly. And when you take it outside it really pales compared to a larger nitro heli. But to set one up right, it costs pretty much the same as a Raptor 50. If you are concerned about outgrowing the heli, I think its capabilities will keep you interested for a long time. I just think eventually you're going to want something bigger. If you want to stay electric, I would suggest the Trex 600. For nitro, the Raptor Titan, Sceadu evo or MA Razor all look good.
