Product Information

Telemetry Features you expect from Jeti

Simple Altitude telemetry sensor just works, find out your altitude, air pressure or temperature. Simple Plug & Play solution.

Easily monitor your Motor & Battery

Stop guessing your flight time. Jeti lets you know exactly your used battery capacity (mAh), battery voltage (V) and how many Amp is your motor/propeller pulling. No longer you have to deal with damaged batteries or burned out motors

Simple Plug & Play solution

Jeti Variometer measures atmospheric pressure and using the obtained data it calculates the altitude above sea level and the rate of climb and descent. The sensor also alerts you if any alarm setting is exceeded.

The acoustic signal consists of 4 different tones (steps) for climbing and the same amount of steps for descending. The step width can be adjusted by the user. The climb signal consists of short interrupted tones, the descent signal consists of long permanent tones.

Monitor and record the quality of your RF Link

The DS-12 transmitter allows you to customize your screen and immediately see how your RF link is performing. You can see A1 & A2 antenna strength in a scale from 0-9 and Signal Quality as a direct percentage. This allows you to set up custom telemetry alarms to alert you if there is a drop in your RF link.

Every Jeti receiver provides receiver voltage battery monitoring and live downlink. This allows you to set up custom telemetry alarms that will alert you if there is a drop in your Rx battery.

Change your Background and Profile Images

Customize every screen and play with any background. Jeti allows you to upload any image and even customize the location on your screen of your transmitter.

Device Explorer in your transmitter menu and setup servo Fail-Safe positions directly using the Tx screen. No need to keep rebinding receivers or to keep them in accessible locations like with other systems.

Assign Functions Wirelessly from Transmitter

Every Jeti receiver provides a direct link for wireless programming. Log in to the receiver using.

Device Explorer in the transmitter menu and assign your servos to any receiver output pin that you choose. Bad Rx location or short servo extensions are no longer a problem with the Jeti system.
