VR with BeamNG (i need advice)

OK, ill keep this brief.
Firstly i cant afford to shell out for an oculus rift DK. so i grabbed the trusty android phone and ordered myself a google cardboard housing. while im waiting for it being delivered i thought id set my phone up ready to use. Long story short i downloaded and installed Trinus VR... nice bit of software which not only feeds your phone screen with a display of whats happening on your tv screen, but it also registers your phones gyro movements and converts them to mouse movements...
now here came the hard part... ive tried in vain to toggle BeamNG's free look option but it wont allow free mouse look without holding my right mouse button down... i honestly have tried but i just cant get it to cooperate. any idea how this can be done?
thanks in advance!

 

I've tried using trinus also. I just taped the right mouse button down. Sorry I can't really help much
