I'm curious. How much time do you have in the R66? I know you're saying that it's not a great tactical or instrument trainer, but do you think the Bell 206 was a better one? That worked out all right for us for about 50 years. What are you basing all of this off of?
I've only flown in it as a passenger.
I do know that it has a cycle setup not representative of any military aircraft and that it doesn't have an IFR cert.
The Skyryse aftermarket IFR setup they're working on is not typical of any other IFR cockpit, because it's premised on a different philosophy of pilot workload than the military currently uses.
Robbies also have a huge reputation for mast bumping.
That’s not what we identified as the problem with the 72 as our intro trainer. The Army wants a trainer to correct a problem of having low time aviators teaching other low time aviators in a flight regime neither are familiar with.
And a whole lot of us did push for a hybrid 3 step model where the 66 or whatever was picked was only a basic air handling trainer with a follow on low cost common systems and tactics trainer and a follow on advanced airframe. That is all but dead in the quest to not abandon the 75 and some of the efforts being buried inside of that program under a wider effort (flight school-West).
And to your earlier point, we have always had people go direct from a trainer to a 47. Couple classes on differential collective pitch and holy hell they can hover the beast. Its honestly not that hard to fly.
The Army has explicitly excluded a hybrid approach from consideration. They're racing to the bottom to find a lower price point. That really leaves the 505, Robinson, and Enstrom, since the 73 and 407 are too pricy, MD is a fricking clown show, and the H125's rotor goes the opposite direction. None of the first three have IFR kits available yet, which is concerning. Training simulated IFR in VFR aircraft is of limited value, and also limits your available training days due to weather.
Yes, they've gotten by with some barebones aircraft in the past. I'd submit that just because they did that before doesn't mean it's a great idea now. Better an aircraft that can fly fleet representative missions now, both IFR and tactics, so that students can get sets and reps on those things before burning a whole lot more fuel on a "go to war" aircraft.
