K-RAT II from Robbe


Orion V. 4 "meets the most modern requirements in terms of construction and aerodynamic design. The model is suitable for fast flights, aerobatics and feels just as comfortable in thermals (thanks to the controlled rudder) as it is for fun and training. Due to the balanced and good-natured flight characteristics, even those changing from 2-axle to 3-axle models will find the perfect model. Not only the less experienced, but also the ambitious model pilot receives an all-round model for almost every weather situation and application.
The design of the model takes into account the widest possible choice of drive components. The fuselage nose has a sufficiently large diameter for standard brushless external rotor motors. Therefore, no expensive gearmotors are required. Depending on your personal preferences, we prefer the 3S version of the 4S, whereas the ambitious model pilot prefers the 4S version. The model has many unique detail solutions, such as its own servo shaft on the underside of the fuselage for elevator and rudder servo, a CFRP rod with laterally attachable wings and much more. As an option, the wings can be secured to the fuselage automatically with quick-release fasteners.
