Is anyone using the Multicopter builders Epic frames like this one?

Hm haven't seen them before, but have to say i like the concept with the session caged below fpv cam... They're not exactly cheap though guessing it is only the frame?

Yes, the gopro seems to be quite well protected and it also looks to have a quite neutral COG as well. There are also other frames I have been looking at like the Shendrones Corgi, but it is known to be hard to build and maintenace, The new Shendrones Corgette and of cours the Armattan Chameleon.

I would like to build oe of those next, but I can't decide yet which of them

I have a feeling the MB Epic will feel a bit strange in the air due to the high mounted FPV cam, so I am looking more to the Shendrones Corgette. But there is also the Chameleon which doesn't have a dedicated HD cam protection, but it could easily be fixed by putting the gopro in some 3d printed protection case.
You can also get the Epic in a 6" version as well. hmm... so hard to decide...
