Graupner,WP TAXI II,4638

WP TAXI II Graupner 4638 TAXI ll-a developed version of its forerunner TAXI - is a true trainer with absolutely uncritical flight caracteristics. Its medium size provides wellbalanced goodmannered characteristics, yet allow basic aerobatics, incl. inverted flight, to be performed. The wing sports geometric washout and a semi-symmetrical airfoil section. The model is inherently stable as a result, rendering it practically unstallable. As compared to the earlier TAXI its assembly has been drastically simplified. Its strength has been increased by the use of novel balsa/obechi plywood. Great attention has been given to profuse prefabrication. Assembly of the fuselage front section has been simplified by the use of extruded ABS plastic parts. TAXI ll can be retrofitted with a steerable nose gear (No 290). The model may be flown with 4-channel equipment for rudder and elevator control. However only 6-channel equipment (throttle added) permits the realistic execution of flight ma-neuvers, such as roll, take-off, Ianding approach etc. Equipping the model with 3-3.5 cm³ engines has proved particularly satistfactory. A flight duration of up to 20 minutes is possible. Equipped with a 4 cm³ engine it will fly highly lively.
