As far as what kind of heli I recomend I really like the 50 sizes. Not to bad on cash but big on performance. I have a Raptor 50, It's a VERY aerobatic machine and is more forgiving than the Raptor 30 because it has a larger rotor disc. Very cheap and very powerful. A crash with an R50 costs just about the same as a crash with an R30. I'm sure there are better helis out there but in my opinion the R50 is the best trainer to 3D ship out there. It is also VERY tough and I personally think the canopy looks great!
