Looking for Messerschmitt Bf 110 Info

[pstrany]

Hi;

I have a few questions about the Messerschmitt Bf 110 C through E.

First, I need to know if there is a external visual indicator for landing gear position, radiator cooler flap position, and/or flap position. This seems to have been a feature on some Messerschmitt products, and I'm trying to determine if the Bf 110 used indicators in the cockpit, or visual gauges, rods or other indicators located outside the cockpit.

I also need to know how the longitudinal trim system worked. What I know so far is that the Bf 110 was equipped with a variable incidence tailplane, and Flettner tabs on the elevators. Some sources cite a link between the tailplane incidence system and the landing flaps (putting flaps down would increase tailplane incidence) but exactly how all this stuff interacted is just not clear. Where the Flettner tabs completely independent of the trim system, for instance, or was there some connection there as well?

Any help greatly appreciated!!
