JU52 Flaps and trimming

So yesterday I got my JU-52, found a nice livery and just popup at the runway and prepared for a first impression flght with the 1939 version. After I realized I should have to use the joystick slider to control the throttle (as my TCA would only control two of the three engines) I discovered that I wasn’t able to adjust the flaps or to trim the airplane once airborne because I wasn’t able to find where were the controls for those!!

May anyone tell me where are those located in the cockpit?

set two buttons. trim up , trim down. Works for me. Flaps wheel is down at the bottom right side of the pilot seat. Big yellow wheel.
