Well, my Gyrator test flight was yesterday. I guess you could say it was sorta successful. It was overweight (20 oz.) which makes everything else worse. It has a 30" dia. delta hinged 3 blade rotor head, (706 sq. in) with a 4 oz./sq. ft. loading, 5 channels and is powered by a throttled Cox TD .049.

Considering the 2 - 5 mph. wind, the rotor spun up pretty well during my run up to hand launch. Their was no tendency to roll or yaw to either direction upon hand launch, so I was happy with that. There just wasn't enough power/lift to gain more than 25 - 30 ft. altitude going upwind and it sagged to 5 - 8 ft. going downwind.

I took it home in 1 piece and immediately began carving weight off the rotor hub and rotor pylon. I ordered some more aileron stock today to build a new, lighter set of blades and will finish them in dope instead of film covering....that should reduce the weight and make it even more stable. I ordered some carbon fiber rod to make lighter pushrods, will change the .35 oz. throttle & rudder servos to .19 oz ones and am considering changing the 230 mah NiMh battery to a 120 mah. Hopefully, these mods, along with a different prop will make it flyable.
