Lippisch DM-1 with NACA-modifications on Lockheed Ventura PV-1 (1:72)
After the second world war the German, almost finished experimental glider Lippisch DM-1 (test-plane for
the projected ramjet P.13a) was tested and modified by the NACA until the end of 1946. During the
windtunnel tests the DM-1 got a lot of changes. Finally the leading edge was a sharp edge, the
vertical stabilizer was smaller and doesn´t include the canopy anymore. Instead the
canopy of a P-80 Shooting Star was used. Below the delta wing a small fin was added. The control surfaces had no gap anymore, so the
airfoil of the outer wing was adapted, too. As it was just a windtunnel-test it had no more moveable
control surfaces. The vertical stabilizer included no rudder and was just a wooden board, like the fin on the lower side. The results of the tests with
the DM-1 influenced the development of US American delta jets (XF-92, Sea Dart, F-102, F-106).

The DM-1 never flew, it just was tested in the wind tunnel. So my model
shows a fictional test plane on a (also fictional) Lockheed Ventura PV-1 with a typical
NACA-paint scheme.
The base of my DM-1 was the wing of a resin kit from Bird Models. I ordered it as a spare part and Rudolf Vogel - the owner of Bird Models - sent me the
wing for little money and supported my project in this way. The P-80-canopy comes
from Pavla. The other parts were built from scratch, out of polystyrene. In contrast to the real plane my model shows control surfaces of cause. I also
gave an airfoil to the vertical stabilizer and the fin.
For the Ventura I used the old, but very good looking kit from Academy. I removed the armament, closed the hole for the turret, added two pilots and
the support for the glider (Ø1 mm carbon rods). The parts of this kit look very
well and fit very good. Just some sinkmarks have to be filled and sandpapered. Inside I placed a block with a short silicone tube. Here the carbon rod of
the display is inserted.
