Did'nt they build the first actual joysticks too? for Ruhrstahl X-4 (prototype), Henschel Hs 293 and Fritz X.

Just wondering about that implementing autoprop to give more rpm to airplane:
I have some memory about reading that after F or G models it was not recomended/preferred to use manual pitch. --> Still I really can't remember where i read that.
