Arrowmax is jumping into electronics with the sub-brand Dash-RC.

ESC looks to be a rebranded Orca R32, the manual is mostly the same.

who knows what's up?

First thing that came to my head seeing the ESC and the programming card: it's an ORCA (and then read on about 32bit, etc. which kinda confirmed it for me.). ESC even got the same price as the ORCA... so I'll probably stay with the "original". But the Dash motors and ESC sure look pretty...
