Hi Daniel

I am flying Raptor 30V1 w TT39 engine and a Hirobo GPH 346 GT w TT50 engine.
The GPH GT is fully metal upgraded version.

The GPH is very good heli, but more mechanical complex than the Raptor 30.
The Raptor 30/50 is much easier to repair and do maintenance on than the GPH.
The GPH is a more precision flying style (F3C) helicopter and not a 3D flying style helicopter as the Raptors.

If you can get a good second hand GPH with beltdriven tail for a good price, you can buy it. Don´t buy a GPH with wiredrive on the tail, the tail control geometry is not good at that version.

But if you are going for new heli, buy Raptor 30/50 V2 !
