For me the EF Yak is only so so ... I say this in comparison with the EF Extra 300. My own experience says that the Extra 300 is a much nicer plane to fly. It handles better esp for IMAC flying. The build is nice, quality of the plane is good for sure. Yeah some some the hardware can be better but they work fine. UC is thin and will bend easily if you are not gentle, its not for abuse.
