I've just oredered one last week. I've been flying Tribute 3D with 370 brushless (5400 kv). I did not like Tribute becuase of the all the flexing in the wing and fuse.

Anyway, the weight of my Tribute including battery was about 15.5 oz. If the Yak's advertizing weight of 14-16 oz includes the weight of battery, the 370 system should be fine.

Did anyone weight the plane yet?
