Maybe this is a more general f16 question but is it possible to just pitch down and come all the way back round without rolling? Suddenly crossed my mind this morning.
Turned off black out to try but couldn’t seem to get it to tip over once inverted
It’s called an outside loop and theoretically yes. The hard part is keeping airspeed manageable. When descending speed runs away and radius increases. You might work up to it by doing a 360 outside level turn and then progressively turn it more and more oblique.
Outside loops are a thing in some aircraft, but they’re extremely dangerous due to hemorrhage risk from negative Gs. Also, IIRC, in the Viper in particular the lubrication system of the engine doesn’t like being inverted (including negative G) for an extended period of time. Since it takes a while to do such a loop at manageable G loading, it might not be possible to complete it without damaging the engine in the real jet. Not sure if it’s simulated in BMS, but it might be.
In general, anything not specifically designed for showboating at airshows has the risk of not liking inverted flight. This may preclude outside loops, which is fine because pilot physiology doesn’t like that sort of thing, either. Besides the “Messerschmidt escape” (a sort of outside split-S, which German pilots used in WWII to escape early Spits, since the latter had carburetor-fed engines that would quit under any sort of negative G), there aren’t many practical combat maneuvers utilizing negative Gs.
