A Radical New Proportional RC All Digital System

A new RC system is changing the mold. It is not a surprise that the crowding of the 72 MHz RC band makes life difficult and dangerous for spectators and pilots. With the big increase in Park Flyers, this problem has expanded drastically. Many of the newbie’s to park flying are not even aware of dedicated flying fields and AMA regulations. A lot of park flying is taking place closer than the 2-mile recommendation from dedicated flying fields or other parks. While these park flyers are not as dangerous as larger heaver aircraft, they still have the capability of disrupting the signals of the larger faster and heavier aircraft. It is a tribute to our organization that a lot of dedicated people try to help out and keep things safe by informing park flyer users of the risks.

Frequency management is another safety issue. At the AMA flying sites there are frequency boards and pins to help share the frequencies. At the Park Flying sites this is not the case. Many responsible people are trying to ask around and be sure what frequencies are in use, but with out frequency pins or procedures this is a risky issue.

Another issue is the indoor RC aircraft size problem. The typical RC equipment size is very restrictive to the size of indoor RC aircraft that can be flown. Small light aircraft are desired in the gym or other indoor flying locations. Even the size of the typical 72MHz receive antenna makes it difficult to use on small indoor aircraft. Smaller receive equipment has been developed, but it is almost always a compromise in performance. The typical crystal filter used in the 72MHz receiver today accounts for a lot of the weight of those receivers making them just too heavy for micro aircraft.

These are the reasons the Plantraco HFX900 System was developed. From the beginning the HFX900 system was design to be used in the gym or park on the smallest of proportional RC aircraft. With receivers as light as 0.8 grams or even 0.4 grams the smallest of aircraft can be flown. The full size monopole antenna for the HFX900 receive system is only 3 inches in length. This is a dream for the small indoor aircraft. It is also great for park flying. At a solid 400-foot range, the HFX900 system has 3 different frequencies to allow multiple aircraft to fly at the park without interference from each other. The frequencies used by the HFX900 system are spaced far apart to prevent the 3 frequencies from interfering with each other. The HFX900 system transmitter and receiver can select any of the 3 frequencies . The system even comes with mixing and exponential options to allow many different model styles to be flown. Best of all is the built in simulation capability for beginning pilots. The HFX900 system comes with the popular FMS simulator software. With a flip of the control stick on activation, the HFX900 system sends out joystick signals to a computer. Now, valuable practice can be obtained on a computer with the same system used to fly real RC aircraft. With the choice of many different models in the software, an aircraft similar to the one to be actually flown can be found. This provides valuable practice to get new pilots started without the high cost of expensive crashes, before the controls are mastered. Even the Lithium battery charger is built into the transmitter.

Systems are available with fully ready to fly aircraft right out of the box. The 7-inch wingspan Butterfly systems comes fully assembled in an aluminum box safely pack away but ready to fly with the attachment of the magnetically attachable lithium battery. The Butterfly full up flying weight is 3.7 grams. Four AA batteries are all that’s not supplied. Now, hundreds of rubber band aircraft can be converted to fly with the 2 or 3 channel proportional systems available from Plantraco. All parts and accessories are available separately.
