A part of the review has been auto-translated.
great gadget with battery ,for model flight
Not tested yet but seems good
Fonctionne tres bien et fort
Se branche en série avec une servocommande (In/Out). Le buzzer se déclenche s'il n'y a plus de signal durant une minute lorsque l'interrupteur est positionné sur On.
Funziona egregiamente, sia con interruttore da tx sia con comando fermo per 1m
second one i bought. first didn't work as described. very low beep when using backup battery. that's in the bin. the second one worked better. it's loud with the backup battery
It's good to help in finding a lost plane but I'd prefer it louder. I connected to the Ruder and it works well. The on-off switch is small and very convenient. 33 days to come at GR (21Oct2020 to 24Nov2020). Everything is OK.
Have it in the plane but been to cold and windy to try.
All items ok
I didn't find an operating manual. It's in good condition in plastic bag and it works. There are some light signals from green and red LΕD's while connected with a battery. I suppose for the charging condition.
