Unable to use the primer at all since the update. Even when assigning a button, it will trigger the animation but no priming occurs.
Iām finding some of the comments on here a bit surprising. I flew the previous version of the spit a lot, and Iāve only had one day with the new version but I didnāt get these problems.
Regarding the right roll, I didnāt get it rolling right on me except when I had right rudder trim in. Itās normal to take off with some right rudder trim and hold some through climb, but youāll need to revert to near centre trim for cruise. Previously it would need between 0.9 and 1.2 deg right rudder trim to fly straight in cruise, now it needs to be close to 0, just as described in the release notes.
As stated in the release notes is a bit easier to control on the takeoff but itās nowhere near a kitfox like claimed above. These are the two planes I fly the most at the moment (youāll see them as my 1 & 2 in the top 5 thread). These are very different to fly.
I found the sounds all good, although I only fly from within cockpit so I wouldnāt experience any external view problems.
Interesting new challenge during approach, opening the cockpit used to be an easy single click, now if I do that the cockpit slides back before I get time to unlatch the door to hold it in place. It needs an extra manouvre where you have to momentarily pitch up just as the hatch slides open to hold it there while unlatching the door.

If you read the patch notes, youād see they added the option to swap between the different pilots through the in-game tablet.
Okay
Compared to the takeoff roll the Spitfire used to have, the new prop dynamics allow the Spitfire to get airborne in about 1/4 the distance it used to take.
My exaggerratted reference to the Kitfox was made because it is a shocking difference in performance for takeoffs - much like the performance of a Kitfox compared to other GA aircraft - and I believe modelled by the same person.
Your apparent superior knowledge and experience has not been challenged. You are correct, they are indeed different aircraft.
This occaisionally happens to me, if I donāt follow the checklist flow.
I suspect youāve already solved this issue. If not, hereās a possible corrective flow to investigate:
- Verify that you turned on the main fuel cutoff (lever with red ball)
- Use wobble pump to repressurize the fuel system AND visually check to see that the fuel pressure warning light goes out (the fuel pressure drops quickly, similar to the 247D but without the analog guage to watch it)
- Prime the engine again
- if your magnetos are still both on and your mixture is still set to full rich, the music should start on que.
If not, try reinstall the Spitfire or contact FlyingIron support directly.
NOTE: Opening the tablet during this process is extremely helpful in identifying underpriming issues.

Flying at 0 boost and about 2500 RPM and even with max left rudder trim I get extreme right roll.
This update has ruined what was a great plane. Uninstalled until someone manages to mod a fix in or Asobo lets us pick what version to install.
This is starting to be a pattern with Flyingiron, they also ruined the P-38 flight model.
Thatās really odd as I didnāt get that at all, it sounds like there is an actual bug affecting you. I donāt know anything about the internals so canāt help debug it but I suggest you raise it as a support case with flying iron because l donāt think that is right.
Iām not trying to claim superior knowledge or experience, I donāt even have a pilots licence.
I donāt have any numbers for the Mk IX but the takeoff for Mk II was 230 yards. Spitfire Mk IIA Performance Testing
On the old version it would take me most of an 800m runway to take off, yesterday I didnāt measure it but itās a lot quicker, maybe less than half the runway. If anything that makes it more realistic doesnāt it?
If you can take off in crazy short distances then you should be able to measure that and come up with a number to feedback against the published numbers.

FYI, if youāre using the Legacy controls, all you have to do is mouse over the Primer and itāll say Underprimed on the tool tip. No need to break out the tablet for that.
Works on the modern xbox controls as well, click left button and the tooltip tells you. My first start after the update I primed until it said ready but then it didnāt start, so I went back to the primer and it said underprimed. I gave it a couple more then it worked. Not sure if the priming wears off over time?
Also I note the motor takes longer to start now so you have to hold the starter for longer.

Thatās good to know. As for priming, any unsuccessful start will require additional priming to be ready for another try.

The baro adjustment doesnāt seem to have improved unfortunately. Even though the control is a dial for some reason it doesnāt work as a dial in the sim. You canāt use the mouse wheel or drag it, instead there are two tiny click spots, one to the left for down and one to the right for up and you can only click them one increment at a time. Itās kind of annoying if the pressure difference is large.
Itād be nice if this was added to the fixes list for the next version, to make the baro behave like a proper dial with mouse wheel etc.
Just wanted to note that I also did not experience any weirdness with the new flight model so far. Flies just as great as the previous version for me (might need some more rudder trim than before but not sure about that). Weird.
Maybe it has something to do with particular controller or assist settings?

When you have the tablet open while priming, you can see that the evaporation of fuel is modelled. The priming level drops over time. The rate is slower than the rate of the fuel pressure drop over time, but it indeed drops over time.
NOTE:
I donāt use any quantitative measurements or an IRL reference table to establish judgement upon aircraft addons. I do follow the provided manual and checklists in combination with available IRL documentation of procedures. I accept that each addon will always be an approximate simulation of the real thing. I appreciate the dedicated endeavor towards accuracy that a developer makes to simulate it as real as possible, but I donāt delude myself.
I am not a real pilot. However, I do want to undertand the principles, theory, physics, and aeronautics that dictate what operational procedures were/are used. I want to experience the unique procedures used for a specific aircraft, yet I understand that they will be abbreviated approximations.
Personnally, my objective to is learn and develop an appreciation for the aircraft. I want to enjoy its representation in the sim to appreciate an airframeās unique characteristics, similar to what the real pilots might have and continue to cherish.
It is not my intent to posses such technical performance data knowledge to be judgemental of an addon outside of a developers direct support forum. It is not my intent to establish myself as a subject matter expert. I do not endeavor to discredit the experience or knowledge of others. To each their own.
Above all, I just want to fly within the beautifully simulated World of MSFS. I want to experience it from inside the cockpit of a high fidelity aircraft addon that allows me to feel as if I was part of and one with the atmosphere. The FlyingIron Spitfire MkIX gives that experience to me - entertainment.

Re-downloaded and re-installed the aircraft from the studioās website. Verified that rudder and joystick did not have jitter towards right, they reported being at dead centre position at rest per the manufacturers software. Checked assistance settings, and set them to the default true to life preset just to be sure. Issue still persists.
Some power and RPM setting where I see right-rolling tendency, all checked at level flight: +12 boost at 2850 RPM, +6/+7 boost at 2650 RPM, +2 boost at 2200 RPM. As noted before this behaviour is dependant on airspeed, at low airspeeds youāll see left-rolling tendency, but this changes to right-rolling tendency as you develop more airspeed. For example the +12 boost 2850 RPM climb power setting produces left-rolling tendency around the recommended climb speed of 180mph, but changes to right-rolling tendency in level flight from about 300mph.
This is no about yaw, or even yaw induced roll but simply about roll. But for clarityās sake I did not touch the rudder trim at all. I also went and deleted the wind layer. As I understand, this aircraft should roll even in level flight due to large torque forces of a 1720 hp piston engine (torque forces being very slight in GA aircraft in comparison where you should see mostly yaw effect), however this should be to the left. I donāt recall noticing this rolling behaviour in the previous version. Itās also odd that the aircraft rolls heavily, but for example does not seem to be experiencing any notable amount of yaw from P factor during high power climb.
If lots of people are really not seeing this, Iāll go and open a support ticket.

Iām so used to clicking āAā button on the controller and using the LT/RT triggers to adjust. I saw I had a Set Altimeter binding and tried that. It worked!!!
Out of nowhere that key works now where it never worked right for me since forever. I wait till ATC finish giving me instruction when I press the key just to make sure Iām not too early. So far so good. Iād like to see an onscreen notification for the Aileron Trim so I know itās working right. Thereās no visual tell which would be nice.
As for priming, I made a binding, it finally animates for me but Iām not sure itās actually working. How many pumps typically? I go one pump at a time for about 10 but no start. I havenāt a clue here. Yes fuel, pump, mixture and etc. is set, Iām very confident Iām not missing anything.
Around post 1145 in this thread is the priming chart. You can give it a couple of extra to be sure.

As I had kept the previous version (1.1 hotfix 1) I tested that and it does not seem to exhibit similar behaviour, I got various amounts of left-rolling tendency from it.
I also noticed that this seems to be the sole high powered piston single (and P-38 is very exceptional in this regard anyway, due to having the props rotate in opposite directions) that has been brought to the new prop physics, so this might be an issue on Asobo end as well.
I get a lot of roll in flight now with latest version - have to use loads of trim to stop it rolling.
Also on start, unless throttle is much higher, it doesnt start wellā¦
Are these bugs?
Good work on putting some numbers on this, letās me reproduce to see if we get the same experience.
Iām doing the tests now and will edit this post with results. All of these are live weather, but light wind occasional cloud, I am over ocean to avoid land turbulence. Steady at 4000ft in cruise.
2700rpm boost 7. Speed 290mph. This plane is balanced with 4.1deg pitch and -1.3deg rudder trim. So yes Iāve had to put left trim rather than right and itās a bit higher than I used flying slower yesterday, but not unreasonable given the change to the trim tabs posted in the release notes. Approximately every minute itās rolled a couple of degrees to the left which I have to correct.
2850rpm boost 12. 320mph. Balanced at 3.7 pitch and -1.1 rudder. This is perfectly balanced with this trim, after 1 min no correction needed, still level.
2200rpm boost 2 . 245mph. Balanced at 3.9 pitch and -1.0 rudder. I popped to the bathroom and it was still on when I got back. 
Just a very gradual roll to the left which U correct every couple of minutes.
Full throttle full prop. 3000rpm boost 18. 320mph. Balanced at 3.5 pitch -0.9 rudder.
2500rpm boost 3, 235mph. Balanced at 3.9 pitch -0.1 rudder. Then I got back to land, wind must have changed because I had to go to -1.4 rudder.
Itās clear that Iām getting very different results and I donāt know why. Mine is xbox marketplace, I wouldnāt expect it to be different from the direct download and I donāt know what else could be influencing this.
