flmgrip,

Note: My R60 has approx 5 cases through it.

The Raptor 60 will accomodate 680mm blades. I have 686 MAH blades with 97mm Model Sport tailblades and they clear fine.

There are no issues that I know of regarding the boom and boom supports. The boom is the same size as the Concept 60 which is ~24mm. It is plenty strong to hard piro manuevers. I was leary of the higher mounting points on the rear of the frame but I have not had any issues and my 401 gain is up around 80 in Idle 1 at 1780.

There is a long boom & torque tube set out from TT that allows for at least 700mm blades. HeliHut has the boom for a whopping $13 and the torque tube for $18. Not bad. I am not sure what length blades but seems like I heard that 710mm will fit. I have two of these sets on standby and will be going to a R80 before long swinging at least 700mm blades.

The only problem that needs attention is that the torque tube ends were not secured properly to the tube and would let go. This was addressed last fall and the fix is to drill and pin the tube with piano wire. But as far as the boom wall being to thin or the boom support system being weak? Not heard that one.

This is an EXCELLENT 60 that has unfortunately been clasified as a "Raptor" when in all actuality it is a much better design. I am having fun with mine and I'm not going to cry when I put here in the dirt!
