from bolt hole to bolt hole its 19.1mm or 7 1/2 inches
this is on the 50 size diamond head.
maybe someone else will chimein withthe dimensions on the 60 size head, both versions.
i have several of the diamond 50 size and they perform very well with the rotortech carbon blades. my 58d uses 4 rotortech 610mm and my seaking does well with 5 550mm wood aerotech blades. none use a stb system.

I think thats 191mm or 19.1cm Emile

And dont take any notice of how well he says it flies. He can make a brick fly superbly......unless he forgets to hook up the pressure line or he is at the Nats Get an opinion from someone with normal flying skills!

Talking of which, have you got your Nats entry in yet Emile hehe. Gotta get started early on him

ooops!! yeah 191mm/19.1 cm is correct, thanks for that Peter!! i guess the tequilla hasnt worn off yet
as for the nats entry, er, ah , yeah, almost got the application filled out. yeah thats it
oh and thanks for that compliment but with the right blades they doo handle well. gonna experiment with some other brand blades this year to see how they compare to the rotortechs.
i have to add however that one should stay away form the foreign "3d" blades for this head as they do some scary stuff in flight! dont ask how i know

looks like you are needing the dimensions from the 60/900 size head then and not the diamond (30/50)
