Airplane plus engines in 1.7.3 have no animation

[RickyOri]

Airplane plus is surely the best mods providing stock alike parts for planes and even if its last update is for 1.6.1, it works properly for 1.7.3, tough it's engines have no animations, rotors don't spin even if they provide thrust and still function as well, So here's my question: is this a compatibility problem with the game's new version or just something adjustable?

I believe it uses Firespitter for it's animations. Try installing the most recent version of it - Roverdude maintains a version.
