Re: What were the weight savings from removing FW 190 outer wing cannons?
"The guns by themselves didn't weigh anything like that much - the 'Waffen' weight must include associated equipment, presumably to do with mounting the guns."
You're right, Tony, the basic MG-FF with EA-FF, ZVKS-FF, DS-FF, and EPD-FF weighs only 28kg (from the handbook of 1939, reprinted in October 1940). But, I imagine, that you also need to take into account the weapon mounting and its wiring and firing indicator, as well as the air bottle with its mounting and plumbing.
I have found no speed loss yet for the mounting of the MG-FFs in the Fw 190. But, I have a report on the difference in speed for a Bf 109E-3 with and without its wing-mounted MG-FFs. The difference was considered as Zero. There were 4 test flights, which gave the following results: 31.1.39 w/o 467 km/h, 8.2.39 w 467 km/h, 15.2.39 w/o 467 km/h, 16.2.39 w 466km/h. When the MG-FFs were removed, the openings in the wing leading-edge were covered.
