Install the FLYMATE Glider unit 

Mount the Glider unit, make sure the GPS antenna (1*1cm) on points up and has a free view of the sky from under the canopy or through Glass/Aramid fibre, mounting under Carbon fibre is a no go. If you have a TEK nozzle installed, attach it to the GPS/Vario unit. Place the 868MHz antenna flat in the bottom of the glider, again NO carbon fibre below the antenna, a piece of Velcro is fine for fixing it. Plug the GPS/Vario unit in to a free channel of the receiver for power supply (5-9V) and control signal. 


SkyNavigator set up 

Update SkyNavigator to latest version, current version at time of writing is 1.1.05(build 2650), if you get a higher version, fine.  Start SkyNavigator, go to settings select connectivity and enable USB.  Also under Settings, select Vario and enable Vario. Don't activate TEK if you have connected a TEK nozzle, it should be enabled when you don’t have a TEK nozzle installed.  Exit and start SkyNavigator again. 

Getting Started

FLYMATE Ground unit 


Connect to tablet/phone via USB cable. An USB On-The-Go cable (OTG) is supplied for direct connection between FLYMATE and the tablet/phone used for the SkyNavigator app. 


The red connector goes to the tablet/phone, it has the OTG coding telling the tablet to deliver power on the USB cable, black connector goes to the FLYMATE. 


Press the On/Off switch on FLYMATE to turn it on, green/blue indicators should come on immediately. 

In SkyNavigator enable USB and close the app. On next start of SkyNavigator it should say "USB connected)  


Not all tablets and phones support USB OTG connection :-( 

Unfortunately not all tablets and phones support USB On-The-Go (OTG) connections. It is a basic functionality in Android, but not all companies have implemented it in the hardware. 

Use this app to test whether your device is OTG capable  <link to USB test app> 

See list of tested tablets and phones <appendix> 


Connect to tablet/phone via Bluetooth 

Power the FLYMATE from an USB Powerbank/Charger via a standard "USB-A Male / Micro-B male" cable, usually supplied with the tablet/phone.  If buying an extra cable please note the thickness of the MicroB connector, some are rather thick and needs to be trimmed down to fit in the FLYMATE cutout.  ## TBD ## recommend cable to buy (from Lindy) 


Press the On/Off switch on FLYMATE to turn it on, green/blue indicators should come on immediately. 


Setup the Bluetooth connection from your device, look for FLYMATE_2017xx bluetooth device and connect, PIN = 1234. 


In SkyNavigator select the FLYMATE_2017xx device and "initiate bluetooth connection" 

FLYMATE placement = horizontal 

Optimal placement of FLYMATE is horizontal when mounted stationary on a tripod, or angled towards the model if placed on the transmitter. 


The supplied 3M Dual-Lock can be used for mounting FLYMATE either on the edge or on the buttom. 

(Dual Lock is dependable and can withstand the forces much better than Velcro - this is why a piece of Dual Lock is supplied). 



Connect to the Ground Unit 

Connection to the Ground unit can be direct via USB cable or wireless via Bluetooth connection. 


For direct USB connection use the supplied USB OTG (On The Go) cable, the RED connector goes to the tablet, the black connector to the FLYMATE Ground unit. Notice the orientation of the USB connector, if it doesn't fit, please try turning it around before using a hammer to force it in.  (Hammer method already tested, no good ;-) 

Turn the Ground unit on by pressing the On/Off switch on the side of the box in. 

A dialogue box pops up, select "allow" to give SkyNavigator access to the USB connection.  

Make sure to be out in the free when you test, GPS reception indoors is limited, and the GPS configuration is focused on precision, not getting an approximate position in indoor conditions.  


For Bluetooth connection, you need to power the FLYMATE from a powerbank via a normal USB Micro-B charging cable. (watch out for 'thick' USB connectors…) 

On the tablet go to settings, Bluetooth and pair with the FLYMATE, password is 1234. 

Next configure SkyNavigator to use the FLYMATE, done under settings, connectivity, Bluetooth. 

Then initiate Bluetooth connection from SkyNavigator. 



FLYMATE Glider unit consists of 3 parts, the combined GPS and Vario sensor, the main Unit and a Patch antenna for the 868 MHz radio link to the Ground unit. 

**The parts are connected by a 4 wire cable and a coax cable, they can be disconnected, but please take care when doing so, the small connectors takes considerable force to open/connect.** 


The Glider unit is connected to the receiver via a standard patch cable, feel free to replace with other length if required. 


Operating voltage is from 5 to 9 volts.



Wait for GPS lock 

Initial GPS lock can take a while depending on reception quality. 

Make sure to be outside with a clear view of the sky. While GPS lock can be maintained under severe reception conditions (inside, under roof, many reflections), initial lock will take 'forever' under these conditions. 

GPS is of course battery backed up, but without the help of up to date Almanac data from the Internet as the GPS in your smartphone is helped by, first start will take 30-60 seconds. 

Also consider it is set up to only report when stable 3D lock is in place, a 'rough' 2D position is quickly established, but not what we want to use for GPS-Triangle racing. 

In short, have patience during the first start of the day. 

When stable 3D GPS lock is established a blue LED flashes 5 times a second. 


GPS-Vario unit mounting 

Mount with GPS (1*1cm square) pointing UP, and with a clear view of the sky through the clear canopy. Remember carbon fiber (CFK) blocks signal reception, glass fiber (GFK) / aramid (kevlar) doesn't. If model have a carbon fiber canopy, find a placement of the GPS-Vario unit under a glass fiber part of the fuselage. 

GPS-Vario can work in other positions as well, optimum is point up. 


GPS-Vario TEK attachment 

A TEK tube can be attached to the GPS-Vario via the black pressure sensor nozzle. 

It is not required for Vario operation as SkyNavigator has the option to do the TEK (Total Energy Compensation) calculation and thereby eliminating the need of a TEK tube to do the mechanical compensation. 

Lots of fancy words, point is to eliminate a false climbing tone when up-elevator is applied converting speed to height, and only get a nice beep-beep-beep when you are actually in lift :-) 

Patch antenna mounting 

Patch antenna to be mounted in bottom of glider. 

Again make sure it is not over a Carbon filled part of the fuselage. 

Mounting with Velcro/Dual Lock approved and recommended. 


Glider unit mounting 

##TBD##   Somewhere in between :-) 

Make sure to be able to see the Status LED at the end of the unit (next to the antenna connector). 


Power on 

Turn on receiver, and watch status led turn on. 


Status codes 

RED, initializing Vario sensor, visible for 0.5 second 

FAULT = RED light for 5 seconds or stays RED forever. 


YELLOW, initializing GPS, visible for 0.5 second 


GREEN, good to go, awaiting GPS lock 


BLUE blinking, GPS lock and transmitting 5 times a second. 


Back to GREEN, GPS lock temporarily lost. 

GREEN constant, programming mode.
