X-Plane 902 has an instrument limit of 400 instruments for the 2-d panel and 391 instruments for the 3-d panel. 920 will remove these limits, allowing you to build very complex panels via generic instruments.
(An altitude indicator might be built out of 3 or 4 generic instruments, so 400 instruments is a lot for pre-built but not for generic-instrument-based panels.)
The Manipulator RFC has been rewritten…the new one proposal is less complex.
There are a lot of other panel and airplane-related changes coming in 920 too…
