I just got a Gem 2000 to put in a new heli, It was recomended from a good heli supplier, so I got it...

Since I got it, I've heard some negative about them and PCM radios...

Advice on this little sucker?

Jeff

I own two that have been used with PCM radios since I got them.

I cannot imagine anyone having any issues with this gadget; it truly is foolproof. You just plug it into an unused channel slot of your rx. No set-up, no calibration, no nothing. Just watch it; if the light is blinking, you're good to go. If the light is steady, your battery is about to puke. If the light is out, there is a problem in your wiring or circuitry somewhere.

It doesn't get any simpler than that.

But allow me to amend my comments; a fool can be ingenious when it comes to thwarting common sense. These things are produced for 6.0 and 4.8 volts. You do need to match that up...<G>

Thanks Steve,

That was what I was looking for. A guy at our field said he used 1 before and it caused his PCM to have radio interfierence.

I fugured that before I stuck them in my machines, I'd check it out here.

I've got two of the units mounted in each of my Futura SE's and using Futaba PCM receivers. I've never experienced any problems with them. It's been reassuring to see that flashing LED when I'm flying.

I'm using the Gem 2000's on two Raptors, both with Futaba PCM and Revolution base loaded antennas. I haven't had any problems after many flights.

I must have got one that was out of tune (yes, i know it has a pot to adjust the voltage) but when playing with my clycler once it was finished discharging, i turned my heli on just to see what it would do at that low voltage and noticed that the gem was still blinking so i cycled the sticks.......still blinking.......the servos were moving very slow because of the low voltage but the gem was still blinking.have not readjusted mine yet nor do i plan to.I think i will just stick to a regular ESV w/load.

jsut something to think about i am not saying it isn't good and i know it can be fixed with the pot adjustment but just something to check out and make sure yours are calibrated...

DK64,

You're right; it IS something to think about. I believe I'll check both of mine next time I cycle.

BTW, I still use an Ace VoltMaster II, which has been calibrated with a known voltage source, to double-check my rx batteries. The real advantage of the GEM is it lets you know if a pack is about to puke while you're flying.

But it does sound like yours was not working right.

Steve

I allways cycle my battery down to the lowest point and still be safe and then adjust the pot. I have them on all my heli's and they all work great and have never let me down. Great way to get en early warning that trouble looms.
