Looking at maybe getting me one of the battery voltage checker/alarms off of ebay to use on my T Rex 450 and 500 helis...anybody here use one? Maybe recommend one?



If the truth is out there; Why are we in here?

I don't know about the ones that they make now, but the earlier ones would go off too early. By early I mean if you hammered the throttle and would pull a lot of amps in the process the alarm would go off when the voltage would drop below the set point. I really don't see any one using them.

I use both of these and they work good.

Your best bet is just use a timer function on your TX and stop flying when your time goes off.

Chris,

Mark doesn't allow links to that site from here.

What would this alarm do for you that the timer on your TX can't do?

Thanks, TheWoodCrafter

I use the alarm on the dx8 and the tm1000. Some batteries it goes off all the time

Even a stopped clock is right twice a day
