I used Futaba 9351 servos for the cyclic/collective and a Futaba 9252 for the throttle. My choice of gyros was my proven and well liked Curtis Youngblood Solid G with a Futaba BLS251 on the tail. A Fromeco Arizona regulator with a Fromeco 2600mah li-ion battery provides the power to my cyclic/collective servos and throttle servo at 6.0 volts. The Arizona supplies a dedicated 5.0 volts for the gyro and tail servo so no additional step downs are required. My governor is the Model Avionics Throttle Max using the governor mode. The engine I chose was the new OS Max 55 with the Fun Tech 395 muffler. I chose not to run a header tank so I used a OS Max Bubbleless Clunk inside the fuel tank instead of the supplied brass clunk. My main blades are Roto-tech 610's and I used Curtis Youngblood Radix P3105 Stubz replacing the supplied stock paddles as I prefer this combination for my flying style. I set my pitch curves to -12-0-+12 for initial flight. I set the governor for a head speed of about 1900 in stunt one for the first few flights until I decide where the sweet spot is for me. Breaking in the new OS was done with about a 20mph wind and a temp of about 45 degrees. I ran three tanks of Cool Power 30% through my engine very rich and the back plate was cool to the touch. The engine ran flawless as expected. On the first liftoff I was immediately impressed. Not only was the heli locked in with a very rich running engine but it was so smooth on the controls. I used 20% expo on the elevator and aileron but will more than likely remove it soon. This heli feels like it will not need any expo. The Fury 55 really amazed me. After flying numerous heli's it is obvious that this is a winner. I just did some mild forward flight and some mild climb outs and a few pirouettes just to get the feel for it trying not to over do it on the new engine. The dampeners are very rigid so it has a slight shimmy as the head speed transitions on take off and landing. I expect this to diminish as the weather warms up and I start to lean the engine. So far I find it to be as smooth as a Vibe 90 but with a willing, wicked quickness if you want. I was smiling till the sun went down and I put it away. It will be hard to fly any of my other fleet now as this will defiantly be my first choice. Writing this review without an air of prejudice was not difficult. Our parent company Flyco; owns Min Air and we manufacture the Fury 55 here in our facility; so I did not want to give a biased opinion. This is my honest opinion. I am not a hardcore 3-D pilot. I enjoy sport style flying and love to try 3-D but to be honest I look pretty sloppy doing it. The Fury 55 will change that. It responds like no other heli I have flown in a very good way. It has a feel that beckons me to fly it and push myself with complete confidence in the machine. With better weather and more time with this Fury 55 I will report my long term results. The quality of the Fury 55 and the way it flies suggest it will be in my fleet for many years.
