Perfect for Beginners

With the MX-12 and MX-16, Graupner has launched the first two transmitters equipped with its new, proprietary 2.4-GHz transmission technology, “HOTT.”

Like many other manufacturers, Graupner uses interference-resistant FHSS for HOTT. However, this article does not aim to examine the technical background of the new HOTT technology, but rather to give the reader a practical impression of how the new MX-16 transmitter performs in real-world use.

The controller is programmed using the proven and intuitive menu structure, which is modeled after the larger models. With the three available mixers and the three flight phases that can be programmed independently of one another, you can accomplish quite a lot. Among other things, for example, a 4-flap F3F wing model can be easily programmed. In addition to using three flight phases, it’s even possible to use the left control stick for wing camber/decamber and, simultaneously, switch it to “butterfly” mode via a switch. Such features—which are almost essential for some pilots—are sure to get your heart racing. The controller fits comfortably in the hand; all switches are easily accessible and can be freely assigned during programming. The housing feels sturdy. The antenna can be bent up to 90 degrees, and it can also be rotated 90 degrees. Protecting the sensitive antenna is clearly a priority here. The built-in DSC jack can be used, among other things, for instructor-student mode, which works flawlessly in combination with an MX-24s.

Experience has shown that 2.4-GHz systems can sometimes be sensitive to factors such as direct obstruction by objects, people, buildings, or trees. With the MX-16, no reception problems could be induced by blocking the signal or placing the unit on the ground. A binding test—involving turning the controller off and on—was performed several times during flight. The connection was quickly reestablished each time. In the author’s opinion, the MX-16 is a top-tier entry-level transmitter that offers quite a lot of programming flexibility and is often very attractively priced. With the update capability of the HOTT modules, Graupner is focusing on sustainability and thereby enabling future functional enhancements. For all owners of a Graupner transmitter, it is to be hoped that the HOTT system will become the industry standard. Graupner will be ready in time for the start of the new flying season

(Early March) we will be able to offer the appropriate modules for most control systems. An inquiry to Graupner regarding the MX-24s module revealed that it will be available in mid- to late April.
