Trainer Mode

Trainer Mode provides an assisted flight envelope suited to learning -- limiting attitude/rate extremes to make an aircraft harder to lose control of, similar in spirit to a self-leveling "beginner mode" on other platforms.

Unlike Angle/Horizon-style self-leveling, Trainer Mode does not actively level the aircraft -- it flies exactly like normal acro/manual flight right up until the pitch/roll angle would exceed Limit (default 20°), at which point it tilts back toward that limit rather than letting the aircraft roll/pitch further. Gain sets how aggressively it corrects back once the limit is exceeded -- high enough to reliably catch a beginner's overcorrection, without fighting normal flying so hard it feels like it's flying itself.
