By Robbe Modellsport – Available at Aerobertics
The K-RAT II PRO is the highly refined successor to the renowned K-RAT II, now featuring a full GRP (glass fibre reinforced plastic) construction for increased durability, aerodynamic precision, and strength. Designed to meet the latest demands in performance flying, this upgraded model is ideal for high-speed flights, dynamic aerobatics, and thermal soaring.
Whether you're transitioning from 2-axis to 3-axis flight or seeking a versatile model capable of handling a wide range of conditions, the K-RAT II PRO offers a balanced, forgiving flight experience that appeals to both developing and experienced pilots. With its controlled rudder, it delivers impressive thermal capabilities while remaining responsive and fun in powered flight. It also serves perfectly as a stepping stone toward more demanding hotliners.
This aircraft is engineered with attention to detail, offering standout features like:
- A dedicated servo compartment under the fuselage for the elevator and rudder
- Side-mounted wing connection via a 10 mm CFRP round bar
- Secure ‘Multilock’ wing locking system
- High level of prefabrication, especially in the PNP version — just install your battery, ESC, and receiver to get flying quickly
