I could be wrong, but it looks kinda pricey to me. If I guessed right it would be about $530 USD.

That came out a while back - a mix of early 550 / 425 parts (head, gears etc.) and some X5 bits (frame desin etc.). Only from Pitch Up and expensive

It seems that this bird was a test bed to probe new servo layout, and frame design impact on performance. also to expose customers to something different from Gaui to gauge response. when it first came out there was a fair amount of 'chatter' about it, so I think Gaui decided to run with it and redesign the whole works ala the X5.

Looking... Closely again at the motor mount location makes me wonders.. If bigger motor can is going to be an issue... Look how close those cyclic servo are to the motor...

i don't think there is a" v2" but the cf frame could be considered that

The boom diameter's are the same for the 425 and 550
the drives im not sure but the drives fit right in so they should be
I don't know the boom diameters

The main shaft is 8mm for the 425,550, and x5
I know this because I am using a x5 yoke on a 425 main shaft

The 425, are pretty much the same except the 550 uses a longer boom, and blades
Belt or ,torque drive which ever your using
