gyro i will look around and see if i can find a review on it, its an older airframe so that may be a bit of a chore lol....as far as how they fly and compare to other planes, i can say that i have flown alot of different manufactures over the years and omp is one of my favorites, all build quality is top notch, all light weight with outstanding wing loading making them do whatever you want to do. and as far as the yak goes in the size your looking at the roll rate is insane!!! and one of the best parts is they come with complete carbon accessories i.e. landing gear, wing and stab tubes, spinner, and carbon rods throughtout the fuse and wings to make sure they hold up to whatever you through at them. i will look for that review and in the meantime if you have any other questions let me know and ill help anyway i can. you can also call john drake at the number listed on the website and he will be able to help too.
