The Altitude Motor Switch (AMS) is a versatile device suitable for several competition categories where the altitude or motor run time shall be limited. It can be used also as a standalone variometer. The sensor is usually connected between the receiver throttle channel and the appropriate signal input of the electronic speed controller.
The AMS contains a sensitive barometric altimeter/variometer which uses the latest MEMS technology to achieve a high level of accuracy, while preserving miniature dimensions. The sensor is able to detect changes in atmospheric pressure to indicate the change of altitude with resolution 0.1m. Using the integrated high power cables you can directly power the receiver and servos through the AMS from a BEC circuit of the speed controller.

Did you know you can easily copy models and sounds or even upload model pictures from your phone to the JETI transmitter? All you need is a USB C to USB A adapter for OTG storage which can be purchased in any electronic shop for a few bucks. Ask your friend on the airfield to download his model so you can study his setup later!
Calibration of the consumed volume is possible from FW version 2.03.We recommend that you first check SW version in the MFlow2 EX sensor. If will be necessary, update the sensor via the JETI Studio program.
It is also necessary to have the actual device profile (MFlow2.bin) in the “Devices” folder on the transmitter’s SD card. Actual device profile can be downloaded during the MFlow2 EX sensor update, or you can update your transmitter via the JETI Studio program. The file (MFlow2.bin) will be automatically updated on the transmitter’s SD card.
Calibration procedure (as example): Leave the “calibration” in the default setting (1,000) and make the first test flight (or run a pumping test with the correct type of fuel). In our example the sensor in the default setting measured the consumed volume of fuel 1159 ml. After a test flight (or pumping test) we measure the exact volume of fuel consumed from the tank, for example, by pouring the rest of the fuel from the tank into the calibration cylinder. In this way, we can exactly determine “real consumed volume” from tank. Then in the calibration menu fill in this exact volume in the item “real consumed volume” (980 ml). The flow coefficient is automatically set to the exact value (0.845). You can reset the calibration at any time and select another (more accurate) value to suit.
One of the most impressive European made sailplanes that we have ever seen, the Grafas 3.1E flies as good as it looks. Gentle, smooth, and very long flights are the standards for this beauty. The careful use of composites with competition balsa, creates a good light structure that will hold its shape for a long time. The synergy of low weight and strong structure is very unusual in a production sailplane and can only be achieved with careful attention to design and construction.
The entire model is constructed using free-flight techniques. Top Model uses the latest construction techniques such as CNC milling and laser cutting. The wings as well as horizontal tail are all balsa built-up with Carbon Fiber main spare and leading edge. The fuselage is gel-coated fiberglass with white finish. Whole model is covered with Ultracote. All control surfaces are hinged with adhesive tape. This fully built sailplane needs only basic assembly and motor/radio installation. The 3-piece wing and full flying stabilizer are each easily removable for transport and storage.
Great sport or entry level competition F5J/LMR (Limited Motor Run) or ALES (Altitude Limited Electric Soaring) electric sailplane.
The JetiBox Profi is designed to be an easy to use mobile wireless device for viewing, processing and storing your telemetry data or for programming JetiBox compatible equipment. The JetiBox Profi also is designed to work in two different wireless modes with the Jeti Duplex 2.4GHz systems.
In Monitor mode it can only receive its data by “listening” to the existing connection between a Duplex 2.4GHz equipped transmitter (or transmitter with Duplex module) and a Duplex receiver. In Telemetry mode it receives its data directly by “listening” to the existing Duplex 2.4GHz receiver and installed sensors or telemetry equipped ESCs like Jeti Mezon.
JetiBox Profi can be used in Standalone Telemetry mode only with R4US, R5US, R6US, R7-9-11US, R14-18US Receivers running Version 3.11 of the Rx firmware (See Firmware Updates Page).
Telemetry Functions & Alarms All of the telemetry screens have been updated to support the latest Duplex EX sensors. You can display up to 20 different telemetry parameters on 5 different desktop screens and also monitor the output of up to 16 transmitter channels. In addition to monitoring telemetry in real-time, you are able to record telemetry data for review after the flight. You can then view the logged data using the Jeti Graphics Flight Monitor Interface. Another cool set of function are the programmable alarms. This has proven to be a bulletproof way of enhancing safety for both yourself and your model. You can simply set a receiver battery capacity alarm for the desired capacity used and once that number is reached the system acoustically and visually gives you warnings.
Parallel Telemetry The JetiBox Profi can work as a parallel wireless monitoring device for your telemetry digital data stream with the Jeti DC/DS-16 2.4GHz Duplex radio system. This allows all of your telemetry data to be safely monitored by your co-pilot while you are flying your model. We think this is one of the best ways to both fly your model and safely monitor your telemetry data.
Sensor and Jeti ESC Programming All Duplex EX telemetry sensors can be directly plugged in or wirelessly connected to JetiBox Profi for programming and data viewing. Also, the entire line of Jeti SPIN and Mezon ESCs can be directly programmed using the JetiBox Profi.
The JetiBox Profi is designed to be an easy to use mobile 2.4GHz wireless device for viewing, processing and storing your telemetry data and/or for programming your JetiBox compatible SPIN/Mezon ESCs and Telemetry Sensors.
