ModelMatchThe 12X features patented ModelMatch technology thatprevents the operation of a model if the wrong model memoryis selected. During binding the receiver actually learns andremembers the specific model memory (1 through 50) that thetransmitter is currently programmed to. Later, if the incorrectmodel memory in the transmitter is selected and the receiveris turned on, the model simply won’t operate, preventing apossible crash. Change programming to the correct modelmemory and you’re set to fly.Failsafe FunctionsThe JR R1221 receiver features two types of failsafe: SmartSafeand Preset failsafe.I-18
SmartSafeThis type of fail-safe is especially ideal for most types of electricaircraft and is also recommended for most types of gas- andglow-powered airplanes and helicopters. Here’s how SmartSafeworks.Receiver Power OnlyWhen the JR R1221 receiver only is turned on (no transmittersignal is present) the throttle has no signal output. Thisprevents the arming of the electronic speed control. In glowpoweredmodels, the throttle servo has no input so it remains inits current position. All other channels are driven to their storedfail-safe positions.After ConnectionWhen the transmitter is turned on and after the receiverconnects to the transmitter, normal control of all channelsoccurs. After the system makes a connection, if loss of signaloccurs, SmartSafe drives the throttle servo only to its presetfail-safe position (low throttle) that was set during binding.All other channels hold their last position. When the signalis regained, the system immediately (less than 4 ms) regainscontrol. Any time the transmitter is turned on and operating witha DSM system, the amber light on the rear of the transmitterwill be on solid (not flashing) and the red and blue lights on thetop front of the transmitter will also be on solid (not flashing)indicating the system is outputting signal and operating.Failsafe for JR/SpektrumPreset fail-safe is ideal for sailplanes and is preferred by somemodelers for their glow- and gas-powered aircraft.Receiver Power OnlyWhen the JR R1221 receiver only is turned on (no transmittersignal is present) all channels including the throttle have nosignal output. This prevents the arming of the electronic speedcontrol. In glow-powered models, the throttle servo has noinput so it remains in its current position. All other channels aredriven to their stored fail-safe positions.I-19
