We are pleased to offer our Seagull Glide system (patent pending), a
revolutionary Variometer and Soaring Tool for model sailplanes.
With the Glide system, data previously available only
on full sized gliders is provided to the pilot in real-time.
Unlike other limited feature variometers on the market,
the Glide system has a fully digital wireless link, data logging,
tremendous expandability, and many other advanced features.
Unit comes pre-configured. No computer required!
New: Do you fly your sailplane FPV? Consider the Glide Data Recorder + OSD Pro, for the ultimate in variometer features and performance!
Glide Dashboard mounts on Radio or in your Pocket
All hardware and software is included for these features:
Varying tone variometer with advanced electronic
Total Energy Compensation – no cumbersome TE
probe to install
Minimum sinkrate, climbrate, averaging period,
and other flight monitoring parameters are fully adjustable
while your plane is in the air
Full support for English and Metric units
Airspeed measurement from 2 to 290 MPH
Altitude measurement with 1’ resolution
Receiver battery voltage monitoring included
The Seagull Glide system has 3 main components:
Glide Dashboard Receiver - this unit displays telemetry data, and provides varying tone variometer and programmable alarms (built-in speaker and headphone jack).
Onboard Glide Data Recorder - this unit collects and logs data from built-in and external sensors.
Onboard Telemetry Transmitter - this unit sends the data from the Recorder to the Dashboard
Small, lightweight Glide Data Recorder
Do you need even more data? Our Glide system is fully expandable, with a whole host of additional sensors, available below. Here are just a few examples of what you can do with additional sensors:
Monitor your motor-glider's electric power system with our Electric Expanders. These units measure power consumption with a small ring that is placed over one of your battery wires. No need to add an inline sensor!
Locate your lost plane with our GPS Expander. And, display your flight path on Google Earth, either live at the field or downloaded later, with the GPS Expander.
Monitor your Spektrum or JR Receiver's RF performance in real time, with our Spektrum FlightLog cable.
Google Earth Realtime and Recorded data interface!!
