What GPH version is that heli??? The first edition of the GPH was wire drive and it was plagued with a lot of gliches for wire drive issues............Then they fixed releasing the belt drive.

Also check this pics to see if this are the same Hirobo Blue Anodized Upgrades:

Bottomline, IMO I think $500.00 is a good price.
Also if you are a begginer you can put a FMA Auto Pilot that can be a great help.
Also a Futaba 401/9253 will hellp you a lot with tail.

Pictures of the GPH 50 Assembling

I take this address from a Hungarian heli web site.
Take notice that the heli in the pics is the tube drive version.
The GPH 50 sell by Altech in USA is belt drive.

I pay for my GPH 50SE kit US$399.00.......... In my field there are 3 GPH 50īs including me and belive me, this heli fly likes a dream. It does not have any kind of flutter like Sceadus and Craptor.
One has a OS 50 and the other two has Webra 52AAR with Weston one piece pipe.
