So after two days messing around with legacy airplanes and the Legacy Importer I have some thoughts that will perhaps be of interest to other newbs who got the program for the holidays and are still getting their feet wet in the legacy thing.
Thought 1. THANK YOU Wookiee for the Goose. The difference between a carefully developed native plane and a jiffy legacy conversion is enormous. It is a delight to fly and your extra effort is much appreciated. The only tweak I made was to turn off "available for AI" since although it was fun to see a Goose on the ramp at every airport I visited around the world, it wasn't very realistic!
Thought 2. Jiffy legacy conversions do have their uses, at least for now, and at least for some users. In my case, these rough, partly-functional conversions will tide me over until there are some categories of planes, mainly vintage, available in more fully developed form. I know that the flight models aren't accurate (although some are surprisingly not bad) and I miss having access to many of the secondary controls and systems. When I want to fly planes that handle like they are supposed to, I still have Prepar3d and FSX. The legacy planes, for me, are just when I want to do what FS2020 does best - peep at scenery - from an open cockpit biplane, or use a P-51 to get around a little quicker than the Bonanza. For that reason, I don't need, and am not trying to convert, every warbird in my P3D hangar. Just a few that fly decently are fine, and I don't need dozens more with basically similar performance. When proper native versions come out, I'll happily delete the legacy planes, and maybe eventually build up a 300-plane hangar in FS2020 as I did in P3D. Or maybe not! Thus far, even with the stock aircraft, P3D still feels better as a simulator to me, and I may keep FS2020 mainly for scenery peeping, which doesn't require many different rides.
Thought 3. That Legacy Importer is a mighty impressive piece of programming. It deserves a lot of praise for being able to turn many FSX airplanes into reasonably flyable FS2020 models in 30 seconds on almost a turn-key basis. Good, no-nonsense interface, too.
Thought 4. Some planes jiffy convert a lot better than others! Personally, I have no interest in converting large or complex aircraft that I'm used to flying with pop-up panels or a lot of use of the mouse-clickable VC. That means basically nothing with a glass cockpit or a lot of complexity, and the biggest "big iron" I've converted so far has been the Just Flight Lockheed 10A. If you are interested in these jiffy conversions, it might be best to stick with the more primitive types.
Thought 5. Legacy converter success seems to vary by publisher, not surprising as they each have their habitual ways of doing gauges, textures etc., some more "standard" and amenable to conversion than others. My results thus far:
- Flight Replicas P-40N converted well; I have not tried other Flight Replicas products, but the P-40 is so good that I'm tempted to try one of the 109s.
- Golden Age Simulations planes convert well, give or take some funky sheen/opacity on the textures.
- Warbirdsim P-51s and Warwick Carter's T-6s converted quite nicely.
- Rob Richardson's planes seem to convert well. I did the Vampire F.3 and it is delightful. I know that others have had success with Rob's other planes.
- I have not had any luck with Alabeo/Carenado planes. They end up with missing parts and/or gauges.
- Milviz is a bit of a mixed bag. The F-86 looks fine but I have some doubts about the flight model. The P-38 that came with P3Dv4 has a few glitches but is flyable. The Corsair had missing skins and just didn't work.
- A2A I have not tried. If their hype about Accu-Sim is even partly true, with so much of the flight model bypassing the standard FSX/P3D process, then they shouldn't convert easily.
- Just Flight/Aeroplane Heaven seems okay. Several people on this thread have reported success with these. I haven't tried many of them.
- RealAir's Spitfires seem to convert beautifully, thank goodness, since we won't be getting any authorized native conversion of these. This is the one plane that I'm willing to learn how to tweak legacy flight models for the sake of having.
- Virtavia's FSX-native products seem to work okay for me so far.
Thought 6. The one consistent flight model issue that many legacy conversions seem to have is wild swinging on takeoff. When I did the Iris P-40E and PC-9, this was so severe that even full trim, rudder and differential braking together couldn't keep it straight. Editing the scalars for these in the aircraft.cfg did not seem to help. My solution was to switch to the legacy flight model and dial down the p-factor, torque and gyro to 50%. That still gives more swing than it did in FSX, but at least it's controllable. It seems to help make other legacy planes behave more like they originally did, as well.
Anyway. I hope this is helpful to someone.
