Works much better with trim 5 degrees up and the rudder trim! Thnks.

 

Will also try without the rudder trim, only pitch trim.

OK, I turned off rudder assist, 5 degrees nose up trim and it worked pretty well.  Thanks.

I end up deciding my original 5 degrees is too  much.     Just 1 or 2 degrees is better,

In any case though, I can't help but wonder why in the world don't these aircraft developers pay any attention to stuff like this?...they should be designing their flight models to overcome whatever blemishes are within the base sim's physics...there are probably less than a handful of payware devs that will do this and I don't understand why they ALL don't do it...it's really their job, not ours. For me, it's the reason I'm willing to pay for an aircraft.

Do planes in MSFS have the ability to set different handling characteristics for flight and for ground? My impression was that ground handling itself in sim is somewhat bonked and if you adjusted for ground handling, you messed up flight handling. That's just my impression though and I may totally be wrong.

If you are talking about playing with your rudder sensitivity that is correct. I think they are talking about editing the config files ?

Some issues people have are of course realistic.  For example the Cherokees in general have a reputation of acquiring all the glide characteristics of a house brick with full flaps and no power so your Arrow III plummeting when you add full flaps on short final with no power applied is likely true to life.

Other issue though are exaggerated or wrong.  Nose down trim is not a good thing when taking off in any tricycle undercarriage aircraft but a bit of back stick SHOULD rectify the bad trim - it doesn't and nose down or neutral trim have you skittering all over the runway.

 

TLDR with the arrow -  take off with a degree or two of nose up trim and remember you need more power applied than you might think with full flaps

 

I played around with elevator trim, and after a few  takeoffs, I put rudder assist back on. It works every time with the Arrrow.3. I can nail the centerline on takeoff.

Hi - yes and no I think...first it depends upon which specific thing your changing in the flight model file that will dictate if it effects both ground and air handling, then it also depends upon the new physics modeling that MSFS is supposed to allow for that we haven't had in the franchise in earlier versions...but there doesn't seem to be alot of people who fully understand what all those new hooks really are just yet...which new aspects can be utilized and which are essentially stuck in legacy for now.

For instance, there's supposed to be prop wash but it's either broken or it's not implemented yet...and this is something that can effect both ground and air handling. Then there's various rudder adjustments you can make in the flight file which will also effect both ground and air handling. Engine torque effects both too. But there's also things like contact points and nose wheel steering adjustments that effect only the ground handling.

But your mostly correct in saying that adjusting one thing can effect another. Flight modeling has always been a precarious balance teetering between real world numbers and/or real world behavior and it has been nearly impossible to get both of those things perfect in all phases of flight and ground handling for any particular aircraft.

Thanks guys. I had this exact issue and a bit of nose up trim fixed it. Not too mush or it try’s to take off at about 40 kts. 

malcolm. 

I use ~4 degrees up trim on takeoff and with that, the arrow automatically rotates around 60-65 kts. Sofar I haven't used rudder assistance and I don't think I really need it but wil try if it feels better.
For the flare I also use around 4 degrees otherwise I have to pull the yoke all the way into my stomach. I don't know if that is characteric for the real thing, but in the sim my Fulcrum yoke gives me quite the workout otherwise.
