One thing is for certain, you wont have to wait for systems to catch up on the MH-53....there not modeled LOL, its simple as simple does, the MH-53 follows the default bell set up, but doesnt need the throttle boost at 15-25% torque to get it going ( the old Seaking did ).

Whats happening to you is that your trying to get away before the rotor RPM has got up to speed, look for the torque gauge, it needs to be 90% or above and it takes a while to get there from stand still ( dependant on rotor mass ), if you apply say 15% throttle it will get there a little faster but best thing to do is just sit calmly, enjoy the view and wait for the rotors to spin up, when your up to 100% torque then you can go fly.

Jordans 412 works lightly different as does the default R-22 in that you also have to apply something else....whos name has totally deserted me at this un godly hour, but its a little joystick icon that you have to twist to get full power, you have to do that in Vc or 2D panel, there is no key command for it as far as l know, once you have done that you fly on the joystick throttle lever.

With a good stable FDE you will soon get the hang of helo flight, theres plenty of them out there to try for free before parting with any cash.

Hope that helps.

Best

It will help enormously Michael, thank you very much indeed. All this information is filling in huge gaps in my MSFS helicopter knowledge, and really is appreciated.

Recommended settings for Helo flying - All realism sliders full right, then the General slider just one single click to the left.

Then control sliders to max sensitivity, null zone to minimum, except for rudder pedals, which stay as for fixed-wing.

I haven't tested this, as I only have a few advanced helo models, but the common thread in the Jordan Moores and Nemeth brothers choppers is that they reverse the function of `throttle` and `prop` to what you might expect, so that using the throttle lever on the joystick actually raises and lowers collective (alters the pitch of the blades, same as prop pitch adjustment in fixed-wing), as most helos are flown pretty much at high or full throttle most of the time. The throttle twistgrip is used only for start-up, using the prop pitch buttons to bring the throttle speed up to the point where the governor can spin up the rotors, then all control is handed to the collective. Certainly with the Nemeth models (Mi-2 and Mi-17, S0-76) it makes the startup cycle much more realistic than the more simplistic modelling used in the Alphasim choppers, including the MH-53.

Ironically, I think this makes helo flying much easier in the low speed and hover environment, and if you are serious about finding a chopper to fly the right way, then I recommend the Mi-2 which has full system startup procedures, but a very fault-tolerant flight model, perfect for practising take-offs, landings, heli-taxiing and manoeuvring in tight spaces.

As faras actually controlling the things is concerned, there's a simple mindset - "everything happens, but it may take a while..." You move the stick forward a fraction, and at first it seems as though nothing is happening. The tendency is then to move it forward some more, and then the helo moves, so you think you got it. But you haven't. In fact what happened was that the helo finally responded to your first movement, then the increased movement will suddenly pitch the nose down, and the helo crashes if close to the ground.

Helo flying is likened to balancing a ball-bearing on a stick, but it's actually like balancing a ball-bearing on a stick, viewed through a time-delay video.

Once you cotton-on to the `control-input-wait-see-the-result` idea (and have the controller sensitivities to maximum, the very opposite of what you think it should be to calm a `nervous` helo) it does become much easier.
