Condition: Engine BMW 801 D2/20244
Close engine cowl.
Engine moved forward.
Split cowl flaps.
Armament: 2 MG 151
Course control.
Variometer installation
Robotic system.
Auxiliary wing tanks on Messerschmitt - locks,
Support struts as per BSK 74769

Program: 1. Ram pressure calibration on the test course with or without auxiliary tanks.
 
2. Level speeds with combat and take-off power.
a)   without auxiliary wing tanks
b)   with auxiliary wing tanks
 
3. Flight characteristics.

Results: 1. The check of the ram pressure calibration previously laid down in Flight Report Nr.1, without auxiliary tank, resulted in only minor changes, within the limits of measurement accuracy. As noted earlier, by the installation of auxiliary tanks, the ram pressure indication is lowered, due to interference with the pitot head.
 
While with 190/670 with faired Ju 87 rack, a parallel shift of the error curves is caused by the wing tanks, this here shows a significantly different pattern. Whether this fact is due to the air gap between the wing and tank (using the Mtt. locks), cannot be decided on the basis of this one result.
 
2. Compared to Jabo-Rei with Ju 87-racks, substantial improvement has been made, since after dropping the auxiliary fuel tank, only the Mtt. locks remain, and the resulting speed loss of 3 ./. 4 km/h, should be regarded as negligible.
 
Mounting the auxiliary tanks resulted in lower speeds of 35 ./. 40 km/h below full throttle height and 40 – 45 km/h above, at combat and take-off power. These losses are approximately equal to those caused by tank and rack fairing with the Jabo- Rei with Ju 87 rack
 
3. Regarding flight characteristics, no complaints could be noticed, especially about the longitudinal axis, with this design of the tank rack even in a dive.
