Split cowl flaps. Armament: 2 MG 151 Course control. Variometer installation. Robotic system. Glare shield or flame damper for the side exhaust stacks. Two ETC 50 wing racks with shortened fairing each wing. Program: 1. Stationary engine runs: a)   with mixing tube (Mischrohr) (Klatte) b)   with glare shield Fw as per BSK 74090/91 c)   with glare screen Fw as per BSK 74295 2. Level speeds with flame damper screens and ETC 50 rack with shortened fairing. 3. Flight characteristics. Results: 1. a) The stationary engine runs with the mixing tube (Mischrohr) from the firm Klatte had a negative result. At n = 2200 rpm flames had already appeared, which increased with increasing rpm and reached about 0.5 m in length with take-off power. b) The glare shield should fulfill its purpose, protection of the pilot from glare from the exhaust flames, after an extension of ~ 200 mm to the rear. 2. As can be seen from the enclosed Graph, the lengthened glare screen results in a speed loss of 15 mph (24 km/h) at combat power. The reduction in level speed with two ETC 50 (with the shortened fairing) per wing has already been substantially reduced and is 6 mph (10 km/h) compared to 11 mph (18 km/h) when using the large fairing as per drawing 8-190.862 Z 0 1. Removing the fairing entirely would be inadvisable, as the tests showed a further loss of 6 mph (10 km/h) would occur. 3. Regarding flight characteristics, no complaints were noted either with the glare shield or with the ETC 50, with or without fairing. Langenhagen, 20 May 1943.
