◆ RECEIVER
I have purchased a GWS R4-P receiver,2 pico servos and an IPS 'A' drive with speed controller.I am using a Hitec Focus 3 transmitter. Please could you advise me of the the correct pins to plug each item into. Please visit our Web-site www.gws.com.tw/english/serivce/book/airplane_manual.htm for more information of Receiver connections or refer to the following instrustion.
What means "positive or negative shift" for a reciever. On English web sites, I can read receiver for FUTABA/HITEC or Airtronics/JR, is it very important? Which receiver I need for A Sanwa transmitter? There's no difference on "positive or negative shift" for a receiver. People in France usuall use 41 MHZ. There will be no influence either positive or negative shift. Unless you use 72 MHZ or 29 MHZ, the Futaba/Hitec will be negative shift, the JR/ Sanwa(Airtronics) will be positive shift. As long as you use the receiver in PPM mode, that could be compatible with Sanwa transmitter.
I purchased a GWS GW/RD-8 receiver in May. I tested before installing in a plane and it does not work. If your frequency of receiver is 72Mhz, please check the switch for JR or FP and PPM(FM) mode.
How to consist of GWS R4-P receiver / 2 pico servos / IPS?A' drive with Hitec Focus 3 transmitter correctly ?

Doesn't work in GW/RD-8 receiver with in dependant test ? firstly please confirm your frequency of receiver in correct range (e.g. 72Mhz or other available range in locate area), afterward to check the switch for JR or FP and PPM(FM) mode.
Are GWS receivers and servos compatible to Futaba/Hitec ? Yes, our receiver and servos are compatible to Futaba/Hitec.
I have recently
purchased a fight pack. The receiver that came with the pack is the GWS
R4P pico. The sticker on the backside is the 72mhz and "J". I write to you
because the receiver is not responsive. The transmitter is a HiTech focus
4. All GWS products under well quality control. The "J" is made for fit with JR radio. Since your Hitec is rather similar to FUTABA type. You should ask the shop to provide you a R4P "F" type. You'd better bring you TX & other airborne equipment to the shop, make sure every thing is fine.
I have been told that year receiver GWS R4RF will work with a 10 year old Futaba radio. I can't find any specs to verify this. What are the specs and will it really work with an old? AM Futaba? Our RX could work with 10 year old Futaba radio only for PPM FM not the old AM Futaba.
My receiver doesn't work when I plug in? the crystal, servos, and speed control as the instructions direct me then I turn on my transmitter and then plug the battery into the speed controller. When I do this, the servos imediatly begin to tweet but they do not jitter. The servos and speed controller all work. I tested them with another receiver and the battery is totaly charged. I don't know what to do HELP. First of all, you need to check which radio you are using. If you are using the Hitech Rado then you need to purchase the Futaba RX and if you are using?Sanwa Radio then you need to purchase the JR RX due to the phase shift. Plus, the TX must switch to PPM not the PCM.
I have a R6N receiver with the mini crystal. What can be the proper transmitter that I should use? If I want to change the TX crystal, what type of crystal that I should buy?
For R6N receiver with mini
crystal, you can choose either Futaba or JR transmitter. Both transmitters
are working well with R6N.
My Tiger moth has a system with the??P-4P receiver, two pico servos, and an ICS-50 electronic motor control. I am using my JR 8103 transmitter. On the fourth fight, I wanted to see if the motor would cut off, or the radio system would drop off, so I was flying along slowly at about ten feet, as the battery wore down, when all of a sudden it spiraled down into the tall grass. When I picked it up, both servos were jittering, with the control safaces against their stops, and the motor was jittering on and off. First of all, you need to check which radio you are using. If you are using the Hitech Radio then you need to purchase the Futaba RX and if you are using sanwa radio then you need to purchase the JR RX due to the phase shift. Plus, the TX must switch to PPM not the PCM.
I have an old GWS receiver, R4P. Is this receiver compatible with my JR radio? As you asked about whether our R4P work with JR TX, you have to make sure that the R4P you got is for JR (Shows a J mark on the outside case) and your JR TX has a reception system of FM (PPM). As long as you make sure these, our R4P can work fine with your JR TX.
Someone claims that the transmitters can really interfere with their neighbors' bands. Do you have any diagrams for this?
Our engineer provides our modulation bandwidth spec.

Are there two different sizes of crystals made to fit GWS receivers? I have a R4P II receiver, and your GWS crystal will not fit in it. The pitches on the crystal are too wide apart. I have a number GWSXDR35 crystal. What's wrong? Please be noted that there are two different sizes crystals made for GWS receivers. One is RX crystal (for Pico/Naro receivers) and the other one is RD crystal (for RD8 & R8M receivers). Please check http://www.gws.com.tw/english/product/receiver/crystal.htm for specific information. As you mentioned you use GWX/RD35 crystal, this is for RD8 receiver not for R4PII. For your R4PII, you have to use GWX1/R crystal to get it work.
