Thanks to awesomeperson124 and TehDuck for helping me out with some details.
AG1 and VTOL for gun elevation
AG2 to activate MG34 (German model of MG for you who didn't know)
AG3 for forward gear
Roll to turn
I tried to keep this as realistic as possible, but some details were made up, to avoid empty spaces, which are UGLY.
Edit: There's no reverse gear, it was ruined when I mirrored it earlier -.-

The Jagdpanther (German: "hunting panther") was a tank destroyer built by Nazi Germany during World War II based on the chassis of the Panther tank. It entered service late in the war (1944) and saw service on the Eastern and Western Fronts. The Jagdpanther combined the very powerful 8.8 cm PaK 43 cannon of the Tiger II and the characteristically excellent armor and suspension of the Panther chassis, although it suffered from the general poor state of German ordnance production, maintenance and training in the later part of the war, which resulted in small production numbers, shortage in spare parts and poor crew readiness.

The Jagdpanther had been preceded by two attempts at mounting an 8.8 cm gun as a self-propelled anti-tank weapon; Ferdinand using the 91 leftover Porsche-built VK4501(P) chassis from the Tiger tank competition it had lost to Henschel in 1942, and the Nashorn using a Panzer III/IV chassis. Ferdinand proved to be too heavy and Nashorn small and underpowered.

A heavy tank destroyer design based on the 8.8 cm Pak 43 gun and the Panther tank chassis was ordered in late 1942 as design SdKfz 173. The prototype by Mühlenbau-Industrie A.G. (MIAG) was demonstrated in October 1943.
Production started in January 1944; in February Hitler specified the simpler Jagdpanther name instead of its original "8.8 cm Pak 43/3 auf Panzerjäger Panther".
