T2M Mini Acro quadrocopter Switcher (inverted)

Hi,

what is T2M switcher acro quad labeled from? Any origin product? What protocol?
T2M T5170: www.t2m-rc.fr/de/modellbau-t2m-switcher-T5170.html

Are there any China mini sized (DeviationTX compatible) quads which do allow you going inverted besides Blade NanoQX 3D?

Can we extend the supported models list for acro flag?

Just saw it indoor at the dealer flying (hovering) inverted after pressing the flick switch.

Probably it's not a Blade NanoQX with agility mode so you can flip / roll / fly inverted yourself on 3 axis without over-stabilizing?

Greetings

Thomas

I heard that this quad has no real acro / agility mode like the NanoQX so you can flip/roll/fly it without over-stabilizing yourself?
