Great points . . The 170CDI would not typically be used in a 'Sport' style airplane (we can spec other sizes and type of engines to perform well in Sport planes with out the expense of a YS170CDI). As Atul mentioned, Giant scale and Pattern (which is really ONLY where you would use a 170CDI) are totally different animals. Only a Giant Scale pattern plane would fly anything like a pattern plane . Giant Scale aeros fly great, but they aint no Pattern plane ! We choose our weapons
