I did as you suggested with the 22beta files & decreased the weight on the left side. When I flew the cyclic was closer to what it should be, just needs to be a litlle bit farther foward, lateral was good as it was left of center as it should be(if solo).
Thanks, that convinces me at least that the datas I used for the rotor control travel seems to be right.
I did not notice any change in tail rotor authority, when the aircraft was on the ground, I had to be at full right pedal to keep from spinning left,then change to full left pedal as I increased collective to lift up.
Our FDM (FlightDynamicModel =Flight Dynamics Engine or .air in MSFS) has one big issue, and the makes the helis turns around their center. If the CoG and Inertia are set up correct, the heli will not turn on the ground without engines, but soon a little bit Torque is added, it begins- in Idle, independant of the gear settings.
That's one things which you unfortunately noticed. That's the next thing I will try to prevent, but as the heli is really lightweighted and makes it difficult.
Could it be possible that the data that the files were built off of was inverted?(left side should right and vice versa).
Yes, pilot positions and weight settings had been wrong, as the rotor control travel values as well.
or
Could the data be wrong all together?
Well- our flightmodel you can't compare with the one from MSFS. It doesn't use Lookup-Tables, but Blade-Element-Theory. (Yes, like X-Plane!)
So if you feed it with the correct values, you will get the right behavior. Unfortunately there are a lot of values needed, and if one or some more are wrong, it might be that the behavior isn't right anymore at the end.
There aren't all datas wrong. Only few wasn't right, and with that some others needs a small correction to apply with.
Believe me- it is like in Real Life- it is easier to get a fixed-wing fly correct than an helicopter!
I'll be losing access to our sim for a while, as tonight I am taking it to my business partners house for a couple of weeks for him to work on networking another computer to it and some other things, but I have my pilots operating handbook for the R22 with all specs for each configuration of the R22 models(alpha,beta,betaII).
Would any of that info be of use to you or Groucho?
The Manual can help us for checking the CoG's, and climb rates. Would be great to have all three types in FGFS.
The next step for me is to set the Inertia Tensors, and take a look on the Fuselage configuration....
Thanks for your help, Ranger8!
