RAD models also produces the Kirara. The head looks the same exept it obviously has direct elevator control built in. Looks like the same blades and same head. I would say that if it weighs less than 4.5 lbs it would fly well with that configuration. Check out my post in this forum on "my shiney new Kirara gyrocopter". I Imagine it would fly very similar to the Kirara, asuming the weight is the same.
