Be careful with these as Frsky have had a known issue with them (and others) since 2012. They have used a 18ms PPM signal length rather than a 20ms one like other manufacturers. This means if you have all 8 channels at full deflection the flight controller you are using to receive the PPM signal cannot locate the sync pulse and you will not process the inputs.

They have released a firmware to fix the issue, but this receiver cannot be flashed at home, it has to be sent back to the factory.
T14SG 2015 EU update: The previous version failed, but I bought a new one somewhere round July 2015 and that one works perfect with my T14. For T8FG there is no problem anyhow because it hasn't had a 2015 EU update.
This is one cheap, fine, full range receiver!
I have several of these receivers in multicopters (in CPPM mode) and light planes, and they work perfectly with my T8FG. I have never encountered a single problem. Highly recommended.
Hallo,

dieser Empfnger lsst sich klasse als Lehrer Schler System einsetzen Jumper auf Kanal 3 und 4 und ber Kanal 1 auf die Buchse. Somit bekommt man ein gut funktionierendes kabelloses System
The perfect Rx when size and weight matters. CPPM works perfectly. I add supper lightweight heat shrink to mine for extra protection.
Abosolutely perfect receiver!. I have three of them and all three working fine almost two years without any problems! and price is also much better than original reciever ;-)
Small, light, cheap. Using with T8FG on HLG and Indoor. So far, perfect.
Le user per fare funzionare in wireless il simulatore di volo Phoenix e per fare training wireless fra due radio di diversa marca
Love this RX use it on my WickedWing as a fullhouse mixed glider, price was right and light as the rest, "Camber/Reflex/Airbrakes/Crow" using all 4 channels for servos and a y plug for the RX
Descent RX for the price.does what it says it does so i am happy
