GWS Naro Receiver 6-Channel Standard Pin Futaba - i was lookin at this reciever online, but i wanted to know what NARO reciever means? will it take standard futaba servos, battery, connections, and can i use my old 72MHz radio with it? does it take a standard crystal? Also will micro recievers work the same as a standard one? My radio is a futaba on channel 57 ...what type of crystal would i buy for both the naro and micro recievers? and on last question...what is a pico type reciever?

any answers would be greatly appreciated!!!! thanks in advance!!

pico and micro are very small servos, requireing small crystals (xtals). I believe 'naro' or narrow refers to the bandwidth. Futaba, Hitec, Tower Hobbies have narrow band receivers.

You should be able to use all your stuff with it. Some say you need a brand-specific xtal to match the brand of the reciever (Rx). Micro receivers generally have a shorter range and should only be used on smaller, closer flying aircraft like park fliers. Again, smaller micro/pico rx's need smaller xtals, but the inputs for battery and servos are the same size.

ALL RC radios in the United States are Narrow Band. This was mandated by the FCC years ago and all RC radios in the 72 Mhz range must comply. This is what moved this hobby from 5 available channels to the 50 that we have now.

From what I understand the "Naro" is simply a product name. GWS has several names for their receivers, Pico, Naro, and Micro. The Pico series is 4 channel, the Naro series is 6 channel, and the Micro series is 8 channel.

According to GWS's website ( [link]http://www.gwsus.com/english/product/receiver/r6n.htm[/link] ) all of their Pico and Naro recievers require a micro FM crystal that is available only from GWS.

Once again, according to their website, you must order the specific receiver for your brand of radio. For Futaba/Hi-Tec you will need to order one that is negative shift, which will have a sticker on it that says "F". For JR/Airtronics you need one that is positive shift, and will have a sticker that says "J" on it.

Hope this helps

Thanks for clarifying. I was purchasing a 'Naro' receiver from GWS, and just wanted to point out that 'Naro' does not refer to a special size - it is indeed a full range Rx.

hey guys thanks for the help!!!!!!!!!! you guys always come to my rescue! one more thing...you said it should be used on smaller planes like parkflyers...im really not sure what size park flyers are...but would it work with a 40 engine size plane..specifically the 40 size piper cub?

Looking back to the link I provided above for the data sheet on this receiver it shows the range of the receiver as 1000'. So no, you shouldn't use this on a 40 sized plane. 1000' isn't very far for a 40 sized plane and having a fly off is a very real possibility.

"NARO" is a model name just like Chevy has Corvette, Vega, Camaro, Chevelle and others. Typically Mini and Micro RX's (not all though) have reduced range. They simply don't have the room to install sufficient electronics to get better reception. You MUST check the specs for EVERY RX when considering it for an application.

ALL RC radios in the United States are Narrow Band. This was mandated by the FCC years ago and all RC radios in the 72 Mhz range must comply. This is what moved this hobby from 5 available channels to the 50 that we have now.


Actually, this should read; "All RC TRANSMITTERS in the United States are Narrow Band". There are some FCC requirements for receivers but they have nothing to do with bandwidth, and bandwidth requirements for them do not exist.
NB receiver requirements are an AMA recommendation (ONLY) and can actually only be enforced at AMA controlled fields and events. AMA does not have the federal authority that FCC has. Double conversion, though not mentioned goes hand in hand with receiver design, but again it is not mandated by anyone - it is a manufacturers method of achieving narrow band. Actually, ONE of the methods. For example, JR receivers with their unexplained "ABC&W" circuitry are single conversion, though touted as being narrow band.

And to further add confusion, their servo sizes are also referred to as Pico, Naro, and Micro... sigh...

Come on.. it's a little bit funny.
