If you are looking for an R/C model that is easy to build and exciting to fly, the KOUGAR is for you! This sleek jet-style airplane has a fully symmetrical wing section for smooth pattern-like aerobatics. The KOUGAR will do every stunt in the book, yet it is not difficult for low-time pilots to handle. Ample wing area and a thick airfoil provide outstanding slow speed stability.

Kougar "early Thunderbird" color scheme

Built-in wing "washout" eliminates tip stalling, enabling the KOUGAR to be slowed down to a walk for realistic nose-high landings. The KOUGAR is highly recommended as an introduction to low-wing flying and for beginning pattern competitors.

Don't let the KOUGAR's racy lines worry you. Construction of this sport model is simple and straight forward. The load-carrying and equipment-carrying portion of the fuselage is basic balsa box structure.
Once that is built, you add a molded plastic fuselage top, a molded clear plastic canopy, and a molded plastic cowling, to give the KOUGAR its modern jet-style shaped. The wings are white foam core with 1/16 in. thick balsa sheeting. Tail surfaces are sheet balsa.
