Wow, thanks so much for that feedback, your absolutely amazing! I’ll continue to tweak around with the engine and the drag, I’ll get back to you on that hopefully. Honestly going to be a case of trial and error and think but will be worth it. The gun damage is purely a way to generate a “smoke” effect from firing the gun, doesn’t actually damage the plane. The landing gear popping out has been an issue for a while actually, I think it’s the spring on the gear flexing (as is the usual case on SP). I’ll see if I can resolve that issue too. Ill get back to you with another version soon hopefully. @ChiChiWerx
Crap, it cut off my comment. Continuing:
...the flex exposes your LG out the bottom of the wing, not ideal. Fighter wings don't really flex much, if at all, so flex is not necessary. Also, firing the gun damages parts on your build. Recommend you fix both those issues.
Glide performance is not necessary...fighters glide like bricks, not well.
It's laggy, even on my iPhone 8, still flyable, though. If you were going to do a simplified version, I would recommend deleting the wing fold (it's an AF version, after all), the ejection seats and that beautiful cockpit work and replacing the canopy with "glass"...in a contrasting color it would look great, IMO. I would definitely retain that cockpit view with the HUD glass, though. If it's too laggy, people won't download it.
I like many things on this build, the spoiler/aileron work is fantastic, I really like the lead computing gun pipper, the general quality is great, it flies well/realistically, it's fairly stable and it's not impossible to land. Overall great work.
To recap: Fix the drag/power/fuel consumption issue, fix the LG poking out the bottom of the wing due to the flex (which isn't necessary), fix the gun firing issue and definitely consider a simplified version as I discuss above (I know every artist loves his work). It could be released as is, but you're patient and you want it perfect. Nice work.
It's usually best to flight test a build when it's clean, the numbers you usually see on the net for top speed, max altitude and turn rate are almost always for the clean jet. I flew your jet with bombs and tanks, then jettisoned them to see how it did clean.
Acceleration is pretty good, with bombs and tanks it makes 350 mph plus by the end of the runway. A fully loaded Rhino is probably going to be around 300 knots (345 mph) by the end of the runway. Related to this, you have 7600 drag points on your build...you probably only need half than number; if you fix that you can lower your engine power. You also have drag on your pilots(!)...recommend you remove the drag there. I see a bit of drag on the tanks, which is good and it's too bad SP doesn't allow drag points for bombs.
100,000 gallons of fuel...you've been experimenting with unlimited fuel. I personally dislike messing with the fuel, I understand the fuel consumption issues when multiplying engine power, but it's unrealistic IMHO and it brings about a bunch of problems. I really prefer to decrease the drag points (which are unrealistic on replica builds) and keep engine power stock or even lower it in many cases, which conserves fuel.
Which brings me to this: It accelerates going straight up because you do have a lot of engine power. The RL Phantom did not do that, even when clean and near empty it was barely a 1:1 thrust jet. The F-15 was the first U.S. fighter that could accelerate going straight up and that fact was a big deal at the time. Decrease the drag even more and decrease engine power and you might solve all these issues.
Turn rate fully loaded does seem a bit slow, but clean it turns as well as I would expect. For SP fun sake, I recommend you increase the turn rate, but only by 20% or so. Roll rate is good, about what I would expect, though like the turn rate you could increase it by about 20% (just for fun's sake) and because it would still be what I would consider realistic. As a side note, the F-4 would depart controlled flight if you used the ailerons to roll while the wing was loaded (with the stick back pulling increased G's)...the proper way to roll while pulling Gs was to use the rudder or to unload, roll with aileron, and load back up. Yours doesn't do that, but it's pretty much impossible to do that in SP...however, yours does rudder roll, which is great.
I can see the main landing gear out the bottom of the wings when pulling Gs, this is p
I also put in a little wing flex, only barely noticeable at high g’s, let me know how you feel about that. Btw of this one’s got too many parts I can give you a reduced one (same flight model just removed some aesthetics.)
@ChiChiWerx
I was hoping that you could test this iteration with some of the adjustments you suggested. I took the insignia from one of your planes, but I had to make some adjustments to match it to the actual livery. I've reduced the drag so that when its clean it can make it to yeager (just). Not sure about turnrate, I feel like its a little slow but i wouldnt really know. Also adjusted the paint to give a bit more of a shine, looks a little better imo.
