F-Achelis for Type 9d
 

Is it possible to add the F-Achelis 330 Bachtelze available as an upgrade from the summer of 1942 for Type 9d.
Not be presented 3D model but only the influence of the increasing range of visual detection of targets with 8 km (5 miles), which was the submarine from the bridge at about 40 km (25 miles).
The requirement for the use of FA 330 would be a nice day with little wind and move the submarine speed of 10.5 mph which is really needed for the takeoff speed of this gyroglider without an engine.
