Thanks for this! But I think I'll go with the Vulcan.
According to the website - "One of the huge benefits of this frame is that you are not stuck with a certain configuration. The holes to allow you to create a QUAD, a HEX or an OCTO"
And I think I might be upgrading it to a hex after quad...
I'm into building my first quad... As I don't want to spend unnecessary kit upgrades in the future, I just thought of "why not buy something really worthwhile?"
Is this frame any good, Google does not help me much because it just spews out technical info.
