Elite AMS Competition Altitude Motor Switch, Variometer & Altimeter w/Optional Telemetry for Limited Altitude Electric Sailplane Soaring Categories (FAI F5J Approved)!!!

Get yours, HERE!

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.

How Can I Increase the Accuracy of the Consumed Volume of Fuel for the Mflow2 EX Sensor?

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.

Grafas 3.1E Sailplane Available Now!

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.
