I have to say I'm finding this mission most frustrating myself!
When your co-pilot says "Let me take the controls" is there something you have to do to actually give him control?
First time I just thought he was going to keep the heli flying straight and level so just stopped flying and looked down and started fiddling with the radio buttons only to discover a few moments later we were horrendously out of control. I madly grabbed the stick in an attempt to arrest control only to snap the rotor off and plum it to my doom. Not being exactly sure why the copilot lost control, the next time I was sure to trim the aircraft before adjusting the radio using Helios dashboard on a second monitor so I didn't have to "look down" as such and did manage get the right frequency tuned in however I smash my tail rotor on landing by accidentally pressing the "force trim" button at an inopportune time —my mistake I know. The next two times I tried flying using the Oculus Rift and crashed the first time as once I tuned in the frequency he said I was given back control however I spent too long trying to turn the radio from "OFF' to "ADF" and crashed while trying to turn it on (acturly turning on the ADF is not so easy to do while using the Oculus Rift). The next time I was sure to turn ADF on while on the ground then tuned the frequency once the co-pilot had control bit didn't realise it had in fact picked up the "far north" beacon and flew way off coarse without realising (note; it's actually quite hard to read the compass in the Oculus Rift). And finally this last time, fed up with not being able to read the instruments with the Oculus flew without it but had the heli crash again while it was allegedly under the co-pilots control again!
I know under the "cheats" menu there is the "Active Pause" option which allows you to do things like tune the radio whilst paused, but is there a way to do this without resorting to such "cheats"? I mean your copilot actually says he's going to take control but simply doesn't do it, or am I missing something?
