This is probably a stupid question but I sure don't know the answer. I have a GWS reciever - GWR-4N Naro Type Reciever. I have no idea what battery to get for it. The specs are

General Specs:
- Digital: No
- Range: 1000 feet
- Receiver Shift
- Voltage: 4.8 - 6.0
- .27 ounces
- 1.18 x .79 x .37 inches

Is the votage the only thing I need to worry about or do I need to be concerned with the mAh as well.

Thanks for any help.

DC volts is all you have to worry about. 4.8 to 6 of them

Well, not that easy. While a 6 volt battery will work, I believe I recall reading that you may be reducing the life of your servo if you use 6 volts with it. Ask someone who knows for sure. I thought I saw this question posed today here at RCU, but can't find it now.

You don't say what kind of plane you will be using it in. If you are putting it into an electric plane, you don't need to worry about this. You plug your battery into your electronic speed control (ESC), and the speed control plugs into the receiver. The ESC will feed the RX it's advertised voltage. My GWS 300 ESC outputs around 5 Volts.

It would not be a good idea to use this rx in anything other then a park/slow flyer type plane. The range is limited in comparsion to standard rx and I've found that the interference rejection ability isn't that great. This isn't a major problem on a park/slow flyer since you fly them up close and they are slow in comparsion to higer performance planes

I have one of those RX's.

It is single conversion, and fairly short ranged. I have flown "up and out" with it when I was by myself, but I've also taken radio hits on it when other guys were flying. (it was a 2IM thing, I'm on channel 27, another TX on 50 will hit my RX).

Anyway, chance are, you're going to use the BEC connection from the flight battery as Time Pilot mentioned. In that case, just use the correct battery for your motor/airplane, the speed control will take care of the receiver power just fine.

If you are going to use a seperate receiver pack for some reason, I'd just go with a "normal" 4-cell pack. If you're using Nicads, that will be 4.8volts. If you have a dry cell pack (where you put in disposable batteries), then the pack will start at 6v (4 * 1.5v), and drop off. You'd change the batteries when they get to 4.8v

I also agree with Crashem, I don't think this RX is suited to anything other than small park fliers that will be kept fairly close in.

I am building a slowflyer from scratch. But with a .020 engine
This info helps out a lot.

Be careful. As has been mentioned, the GWS 4N-naro receiver is single conversion, and even with an .020 engine, you can get out of range easily. Don't fly with other transmitters on either.

Otherwise they're decent little receivers that are inexpensive.

Hi,

I have had good experience with GWS naro recievers. I have a 6ch one in a 15 size pylon racer/glider, annd never had any problems. I have had the model very high, flown with others with no probs, and this model is full of carbon fibre. I have another one in a IFO, and they go great. Cheap and light.
