no they had small trim flaps that were adjustable on the ground this i know. the elevator has one of these tabs but the actual elevator trim is acomplished by changine the position of the hstab itself

but the k4 i remember somthing about in flight trim tabs for ailerons and rudder but its all hazy

You are thinking about Flettner Tabs for the ailerons and Rudder.

In fact it seems that no K-4 were fitted with them, it's the WNF/Gyor produced a/c which got them as the flettner equipped ailerons were produced by Diana, a major subcontractor of WNF.

IIRC the flettner tests took place late 1942 with some operational testing done by JG 50 in 1943 with flettner modded G-5 and G-6.

So you have a handful of models starting in '42 (aircraft produced by WNF) that had flettner tabs. In the K-4 handbuch it states the aileron Flettner tabs were 'locked at the moment'.

As for the rudder there are many pictures of K-4 with them - I dunno if these were 'locked' or not.
