elevation, swing & recoil......
My 3 Elefants have the original elevation gearbox. It's not very good but it works.
Windage ( side movement) I never implemented but could be done with a small servo.
I built these models ( or in the case of two of them- rebuilt) more than 40 years ago-
recoil wasn't common back then and I never did it. I'm sure the main gun assembly
could be modified to use a recoil servo controlled by a board like the IBU type.
