At least it works. So I gave this product 3 stars. But the quality is EXTREMELY poor. The marking on the transmitter was wrong, so I mixed polarity. Surprisingly, the transmitter haven't burnt out. The receiver didn't want to work in "on" position. It turned on at the half way of the switch and stayed on only at this position. The 3'rd cell lamp didn't work. I tested it with 3-cell LiPo, and apart from the troubles I wrote about, it worked OK. Haven't tried it in the air yet, so I can say nothing about the distance.

This works reasonably well but only in close range. Beeper comes on at 3.7v which is a bit too early but does tell you when your batteries are getting a bit tired/old.

I bought one these a few months ago and it didn't come with a battery and HK didn't know what kind of battery it would need, etc. I gave up on it. Now reading these reviews I'm not sure I even care. I'll probably throw it in the trash!

Is very usefully! Better for helicopter users because the coverage range is limited. Notify you the battery state of each cell from 2-6 clell with light and sound. Cams with a small 2S small lipo, around 400 mAh. The lenght of the battery is enough for a few days.



Es un muy til!, sobretodo para los usuarios de helicpteros. El radio de distancia es limitado por tanto en aviones puede perderse la sean. Avisa con seales luminosas y acsticas indicando del estado de las celdas en cada momento. La batera de 2S se carga rapidamente con unos 400 mAh. La duracin de las baterias es mas que sificiente para varios dias de vuelo.

Defaults always to 2S, needs manual setting for more cells each time you switch it on.

Finally, I must admit 2 things :

- My model seems to be lightly different... Not sure the voltage for the beep is the same... But sure it can't be adjusted ! Definitively not usefull with heli, I think...

- I use it a lot with planes ! Sure it beep each time I go full throttle, but when it begin to beep at half throttle with my AcroMaster, I know it's time to land...

And always nothing found better to know with planes...

Nice little accessory

I don't really know how practical this device is, it's a cool piece of technology though that should be fun showing off at the field. It would definitly be worth having if we didn't have LVCs on our ESCs. Also a good idea to have if you're using lipos as a Rx pack in a glow plane.
