|The Dominator has helped Boyette's company, Rotor Flight Dynamics, establish many pertinent new safety features which are becoming standard for the gyro industry worldwide. So whether you're looking for a specific training aircraft, or just cruising about on a leisurely voyage, the Dominator is perfect for open-air flying. Available in one and two-seater models and featuring the patented Dragon Wing rotors, Ernie Boyette's new design seems to have what it takes to fly above, around, and past the competition.|

My name is Ernie Boyette, the president of Rotor Flight Dynamics and chief designer of the Dominator. I have been in the field of gyros since 1971, when I built my first Benson kit, to presently designing and building the Dominator.
We provide the gyroplane industry with all the components an individual builder or designer would not be able to manufacture for themselves. We supply rotorblades, rotorheads, and prop and engine combinations, promarily ROTAX and secondarily AMW.
Our product line consists of two place Dominator used for instruction. Additionally we offer 22' thru 29' rotorblades of our own design with a lift capability from ultralight thru 14 lbs. G.W. We are the only manufacturer that test fly's all blade sets prior to shipping.
The Dominator incorporates the Tall Tail design for stability and has become the industry standard by which other companies gauge the stability of their designs.
We offer plans for the purist who builds from the ground up or the totally constructed and debugged aircraft primarily for export or for those who don't want to build their own.
We have a 5 sq ft facility that houses a complete machine shop with state of the art advanced welding capability.
Some of our awards consist of, 1990 - Most Inventive Two-Place; 1994 - Best Two-Place; 1996 - Distinguished Service Award. After Building my first Benson in 1971 and teaching myself to fly literally by reading Dr. Benson's book, I found, through trial and error, that the Benson design could be improved on.
The first step was to replace the McCulloch two stroke engine. It took several years to find a suitable aircraft engine as a replacement. We finally went to a Lycoming engine but the weight of the 150 HP engine and G.W. of 1200 lbs. would require a larger and better rotor design. Throughout the process of building new aircraft I found, in every instance, that the rotor systems available were always lacking. There was always a need for better rotorblades.
So I set about designing what I thought were different types of airfoil designs for a new rotor. Every medium I worked with, fiberglass, aluminum or composites, the airfoils I would end up with were all basically the same. So from my point of view I invented the airfoil we use in our rotor design. It has been said by Check Beaty that nothing new is invented anymore, just improved on.
In 1986 I moved from West Palm Beach to Tampa in pursuit of building gyroplanes as a business. It took from 86 to89 to get the business going and to officially form Rotor Flight Dynamics, Inc.
I went through 12 different rotor designs and with the help of Check Beaty I settled on a specific design. I carefully selected six people for venture capital for the production of my new design I called the Dragon Wign. To make a long story short they put up the money for the extrusion die, the first run of extrusion and the expensive bonding agent.
I taught myself aluminum bonding and started production of the first Dragon Wing rotorblades. From the moment we put it on the market in 1989 we haven't been able to keep up with the demand. This now allowed us, financially, to start R&D on our Dominator gyroplane design.
What makes the Dominator so unique is its high profile design. It sits up very high off the ground dubbing it the long legged mosquito among other things.
The aircraft is the culmination of a lot of design features. Pitch stability in the airframe is the most important. The other goals were the ability to operate off of rough terrain and short takeoff and landing distances.
The rough terrain problem was solved by incorporating a fully active suspension system in the landing gear. This also allows for short landing using the Dominator Stop & Drop landing method. You simply stop at about 2 feet over the ground and drop. This eliminates ground roll on rough terrain. The short T.O. for the 582 or 618 single Dominator is accomplished by a hydraulic pre-rotator allowing a 10' to 30' T.O. roll or 1 1/2 times the rotor length. The average gyro takes 300 to 400 ft for T.O Don't try the Stop & Drop method with other type gyros because you will surely do damage to the machine and probably yourself.
Pitch stabilization is the most important. This helps overcome sudden pitch changes caused by updrafts. In a Benson type an updraft will cause a rapid nose-up pitch. The untrained reaction is the push the stick forward... WRONG... This will cause PIO or porpoising. This may be the correct reaction for fix-wing but not gyros. This will put you in an extreme nose down situation, caused by unloading the rotor, that you may not be able to recover from.
The design of the Dominator under the same conditions will cause the nose to pitch down causing a reaction of pulling the stich back which will load the rotor and not allow the uncontrolled condition experienced in other crafts that occur. This makes for a safe and stable aircraft for those pilots with the least amount of training in type. The proper trained response is to reduce power and ride it out.
The horizontal stabilizer has the function of lessening the effects of stick inputs for pitch as the forward speed increases. This is opposite of the other rotor craft. As speed increases, pitch control becomes very sensititve increasing the chance for PIO. With the Dominator pitch is more stable as speed increases taking the fear out of flying fast in a gyro.
