<p>The transmitter Graupner mc-28 HoTT is the model for advanced model pilots. The mc-28 adapts itself to almost all models. 16 function controls, 120 internal model memories, integrated telemetry and voice messages so as the fast and reliable bi-directional transmission of the Graupner HoTT 2,4 GHz technology, it all makes the mc-28 a true allrounder.</p><p><br></p><p>The mc-28 transmitter features an internal circular polarized patch antenna with very high range and reliability.</p><p>Furthermore the digital and temperature calibrated hall sensors gimbal sticks offer an outstanding durability, reliability and precision.</p><p>Two wide, contrastful displays inform you at any time about telemetry data and parameters and they allow a quick and easy programmation.</p><p><br></p><p>The switches and buttons of the transmitter can be freely assigned thus making them customizeable. There are also 12 mixers available. 8 switch-phase programs with announce function can be adjusted and named for every model.</p><p><br></p><p>Thank to the micro SD card and the micro USB port telemetry data and model memories can be imported and exported. Also firmware updates can so be played without any complication</p><p><br></p><h4><span style="font-weight: bold;">Receiver features:</span></h4><h4><span style="font-weight: bold;"><br></span><p>GR-18 <a href="https://rc-innovations.es/Receptor-Graupner-GR-18-HOTT" target="_blank">Here</a></p></h4><p><br></p><h4><span style="font-weight: bold;">Transmitter features:</span></h4><p><br></p><p></p><ul><li>Aluminum housing CNC</li><li>Linearization of the swash plate servos: Electronic compensation of the non-linear path of swash plates.</li><li>Tail configuration type normal, V tail, delta / flying wing, 2 ELE Sv 3 + 8 (two elevator servos interconnected are now available without the use of free mixers / crossmixers)</li><li>Flap count up to 4 ALE / 4 FLAP: Full support of 8 wing servos, now also without the use of free mixers.</li><li>Switchable flight phase changeover delay: The deceleration time can be switched off for individual channels in the flight phase mode (eg for motor-off in case of electric models or head-lock enable / disable heli).</li><li>16 Phase names</li><li>Wing mixer: Newly designed multi-flap menu for simplest settings of up to 8 wing servos in a flight-specific and clear manner even without the use of free mixers.</li><li>Number of flight phases: (airplane: 8, Heli: 7 + AR)</li><li>Phase trim</li><li>Switchable snap-flap mixer ELE-&gt; FLAP with new offset function for easy course corrections and fast turning</li><li>3 Ring limiters for Voith-Schneider drives and similar</li><li>Channel sequencer for 3 channels for folding propulsion and landing gear flaps</li><li>Logic switches</li><li>Trim memory</li><li>Multi-channel function for channel expansion for up to 14 additional channels</li><li>Music player and internal speakers for voice and music</li><li>Interchange of the servo assignation at the receiver output both on transmitter and receiver</li><li>PPM signal can be set at the data output</li></ul><p></p><p><br></p><h4><span style="font-weight: bold;">General HoTT features:</span></h4><p><br></p><p></p><ul><li>Simple and extremely fast binding</li><li>Range test and warning function</li><li>Undervoltage warning</li><li>Extremely wide receiver operating range from 3.6 V to 8.4 V (functional up to 2.5 V)</li><li>Failsafe, channel mapping, mixing functions and all servo settings are easily programmable with internal telemetry</li><li>Binding of any number of receivers for channel expansion (32 channels maximum)</li><li>Up to 4 servos can be controlled in block with a servo cycle time of 10 ms simultaneously (only digital servos!)</li><li>Maximum interference immunity through optimized frequency hopping and wide channel spreading</li><li>Intelligent data transmission with correction function</li><li>Extremely fast rebinding even at maximum distance</li><li>Real time telemetry evaluation</li><li>More than 200 systems can be used at the same time</li><li>Future-proof by updating via USB interface or microSD card</li></ul><p></p><p><br></p>
