The Do 217J-1 variant was developed and used as a stopgap night fighter to counter the increasing number of bomber raids
over Germany in 1942. Modified from the E-2, the J-1 had a solid, non-glazed nose, bristling with four 20mm cannons and four
7.9mm machine guns.
This brings us to Spring 1943, when the Do 217N-2R22 variant went into production as a dedicated and heavily armed night
fighter. This aircraft retained the solid nose with the four cannon and four machine guns in place. But in addition, it also carried
another four 20mm cannons mounted in the top of fuselage, behind the canopy. These weapons fired upwards at a 70O forward
angle. This unusual armament system was used effectively against Allied bomber formations and was called "Schräge Musik".
Later versions also included the Lichtenstein SN-2 radar system, with its unique antenna array on the fuselage nose.
The SIG Do 217 is strictly a sport scale model and not necessarily based on any particular variant. Instead, we leaned on both
the J-1 and 2R22 night fighter versions of this airplane to create our own R/C version. If you desire, the SIG Do 217 lends itself
to a lot of details that would look great on this model.
The recent and rapid development of super-efficient electric motors and certainly lithium polymer batteries have both served to
make multi-engine models a very practical reality. Our prototype Do 217 models have proven to be outstanding R/C aircraft,
both in terms of performance and looks. We've flown our own prototypes a great deal and can report to you for sure that they
are solid flying models with surprisingly honest flying characteristics. When powered with a couple of appropriately sized
brushless outrunner motors, swinging the recommended prop sizes, the airplane will have a wide speed range and should be
capable of some very nice - although not necessarily scale - aerobatics. While the SIG Do 217 is a comfortable model to fly, we
do not recommend it as a first R/C model. But we can and do highly recommend the Do 217 as your first semi-scale twin
electric model!
