The impaction is an EPP-end model for the impeller of the 69 mm class. By using 10 mm aluminum tubes, the wing is also untapered and extremely stiff, which simplifies the construction costs significantly. On a flight weight of approximately 615 g, the model has positive unusually low speed, so it can be started easily by hand. In designing the model, of course, the aerodynamic design took center stage. Thus, the inputs and outlets as possible were chosen shortly, the fuselage cross-sections reduced as much as possible, and the end strips are made of balsa (<1mm). The impaction can that ever get to drive relatively high speeds, and moving to the high sweep angle very precisely. It is ideal for beginners, and suitable for professionals, at a recommended center of gravity and swings the model can not be exceeded, the model is only about one bag in flight.
Wingspan: 67 cm Weight: approx 615 g Motor: HET-RC EDF motor Controller: 60A Impeller: HET 6904 Servo: 2 x 9 gram Receiver: 4 Ch. Battery: Lipo 3s 2100 mAh (3200 mAh enough space for 4s)
As drive is recommended for use of a 2100 3s Lipo Battery (30 C constant current) of the Mega 16/15/2 motor or the HET 2W20. As impeller, we recommend the HET 6904 or Wemotec Minifan. Material strength, the model tolerates course, much more powerful magnets. Similarly, the space in the trunk big enough for 4s 3200 mAh Lipos.
