It's strange... the only way I can describe it is like a hard crosswind from the right. It actually requires that I point the nose across the runway (to the right) to track the center line during roll-out (no brakes), otherwise the aircraft mysteriously blows off the side.
EXACTLY, EXACTLY, EXACTLY. You've actually hit the nail on the head with this description. For me it happens at random times during landings, irregardless of crosswind component, loadout, technique, etc, but the scenario is precisely the way you mention. I cannot keep the aircraft on the runway without extensive use of differential braking - the rudder alone just does not have enough authority. I've also had the same experiences with the Accusim P-47 behaving the same way as I mentioned earlier. It's very weird.
I will say that I have not experienced the weird random landing yaw since Core Update 1.4; in fact, I had my best landing ever last night. This could be placebo effect, however, lol. I'll be doing some pattern work after work this evening, so I'll see if I can make the gremlin resurface.
Have you updated to Core 1.4 yet, and if so, have you experienced the yaw problem again with 1.4 installed?
Well I do wanna mention that the Real Mustang is known for very unstable rollout and that you have to keep your "Feet Alive" when on the ground. So maybe A2A implemented this Yaw tendency to simulate that. I am not interested in A2A dumbing this flight model down at all. Personally I would like then to maintain as real of a flight model they can get within the confines of FSX.
I'm a bit confused as to who has said what here....BUT...........
Quite to the contrary concerning the roll out in the 51; the Mustang most certainly is NOT known for it's "very unstable rollout". The 51 has ALWAYS been known for her STABLE rollout.
I will say this in added comment. I'm not experiencing what is being described here on landings with the A2A Mustang. I am of course flying it in the sim exactly expecting the same behavior I would be seeing in the actual aircraft.
I don't doubt that the poster here is having some kind of issue and that others are reporting it as well. but my best guess is that it is NOT something inherent in the FSX code or in the A2A flight model. If it was, I'd be having the same thing happen here.
This being said, all tail wheel airplanes share some common habits concerning rollout. First of all, the engine should be powered back so any left turning forces should be negligable if any at all. The main thing about tail wheel rollout is that as speed decreases, so does dynamic pressure on the rudder. Tail wheel steering helps a great deal but doesn't solve the rollout equation entirely.
The platform is a triangle and it's NOT equilateral. It's length is greater than it's width so the main gear and tail wheel form a naturally unstable condition where any disturbance on an arm that long wants to become divergent. The name of the game is keeping any and all departures from a straight track to an absolute minimum.
This means that as speed dissipates and dynamic pressure available to the rudder decreases with that speed, you need MORE rudder to accomplish what was accomplished with LESS rudder at a higher speed.
The last sentence sums it all up concerning rollouts in tail wheel aircraft and the Mustang is no exception.
It's quite stable as far as comparison with other airplanes with shorter coupled main gear and fuselage length, but the Mustang still requires the same care on the roll out as do other aircraft.
As speed decreases, remember, you will be needing MORE rudder for directional control so be prepared to use it. Don't expect the rudder to respond as quickly at 50mph or with as much response as it did early in the landing with higher speed in the equation.
Best rule for landing a Mustang is the same for any tail wheel airplane. Be ready and be on time with the rudder. If you need a touch of differential braking below 50mph use it but VERY carefully and with as little as possible.
I can't address what has been said concerning "tracking sideways" on the rollout as I am not getting that behavior at all here.
Check those controllers carefully and make sure if any crosswind that you are carrying aileron into the wind during your rollout. Keep the stick well back to pin the tail wheel and engage the lock.
