Differences between the Agenda design and the Essence are as following: Conta drive props makes a lot of turbulent swirl wash (about 2 times) than single prop does, so tail planes are in the turbulent air, as a consequence yaw instability and pitch instability are larger compared to single prop. as a result arrow track straight feel is not so good (in drift ) CD -Plane form of Main wing was changed similar to eliptical shape.
-New airfoil for CD.save consumption of battery 200mah,consumption is similar with single prop.Through the above modified design, as Agenda has both merits of G2 and CD it has the best performance.
Flight is more stable in lower speed and better arrow tack straight feel compare to single prop plane.
The above results were gained by experiments with the CD installed in an Essence. The G2 planes have sufficient tail area, if it is converted with CD, the performance is better than that of other planes. In our opinion the performance of a converted Essence is 60% of the benefits of CD.
-Datum line of fuselage is changed. vertical is higher 6cm than that of G2. -Optimized down thrust for CD was applied. -Nose moment was shortened 3cm : to guide turbulent swirl flow. -the distance between main wing and canalizer was lengthened to enlarge tunnel effect. -Height of landing gear is taller 3cm using that of Nuance. improved yaw stability. -Rudder was reshaped to meet 2m limit with
Through the Agenda BJ targeted to achieve 80% of the merits of CD and designed the Agenda to have at least the same or better arrow track straight feel than single prop.
