I solved the problem with the VR for my Pimax 4k.
I installed Steam and then under Tools SteamVR
https://store.steampowered.com
When I start RC8 in VR mode SteamVR is activated and RC8 starts in VR mode.
But I am not satisfied with the quality. The models do not stand on the ground and look bad.
Generally I'm not satisfied with the quality of RC8, worse than RC7 and that's bad!
The models have flaws and the color reflect is bad.
The helicopters do not display the main and tail rotor clearly during flight.
Why does IKARUS sell such a product, from my point of view it is beta, sorry.
