I bought the PICO flight pack with the servos, GWR-4P receiver and ICS50 ESC. The servos work fine, but I cannot get the esc to work. All polarity and connections are correct, and am using 270 mAh 7.2V battery pack. any help would be appreciated.

According to your description, we suggest you to find the reset point first and adjust the throttle and check reverse function as well. I enclose the speed controller instruction for your reference. If you still have question, please do not hesitate to contact us.

I just bought one of your packages that comes with 2 servos, a motor controller, a NiCad battery pack, and a receiver. When I got done charging the servos and such the servos just kept twitching and would not respond to any commands that I would give them. The same wit the motor controller the motor started but I had no control over it. What should I do? Please respond as quick as you can because school is starting soon and I would like to get it working.

If you have JR or Airtronics transmitter then you need to purchase the flight pack with JR receiver. If you have Futaba or Hi-tec transmitter then you need to purchase the flight pack with Futaba receiver. Because of high and low deviation please shift / positie or negatuie.

I have recently purchased a fight pack from a local hobby shop here in Orlando FL.
The receiver that came with the pack is the GWS R4P pico. The sticker on the backside is the 72mhz and "J". The shop has a no return or exchange policy, and I write to you because the receiver is not responsive. The transmitter is a HiTech focus 4. I have been successful with my other receiver so I know that it is not one of the other components.
I hope that your company will be able to help me figure out if I have been given the wrong type for my radio or if the receiver is faulty. I look forward to a reply.

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 ole Futaba radio. I can't find any specs to verify this. It is not on your web site.
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.

I was very disapointed with this product all it does is give be frustration because it dosen't work when I plug in  the crystal, servos, and speed control as the instructions direct me then I turn on my transmiter and then plug the batery into the speed controler when I do this the servos emediatly begin to tweet but they do not jitter. The servos and speed controler all work I tested them with another recever and the batery is totaly carged 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'm having a problem with the GW/CB100/J R/C fight system in my GWS tigermoth. I bought the aircraft and fight pack back on July 15, 2001. It's a GWS system with the    P-4Preceiver, two pico servos, and an ICS-50 electronic motor control. I am using my JR 8103 transmitter to control it.
The first three fights I had with the airplane/radio were flawless. 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. There was no damage to the airframe, but when I picked it up, both servos were jittering, with the control sufaces against their stops, and the motor was jittering on and off. I assumed this was due to low voltage from the battery pack, however, after I recharged all the batteries, the problem persists. When I turn the transmitter on, then connect the airborne battery, the servos still just jitter and the motor jitters on and off. If I then turn off the transmitter, the servos quiet down. I have also tried putting five volts to the receiver directly (without the EMC connected) and I still just get jittering servos. I have also tried removing and reinstalling the crystal to no avail.
DO you have any ideas what could be wrong? Is there a procedure to "reset" the fight-pack or do I need to send it in for service? Do you offer any warranty on the fight-pack?

I am thinking of buying a GWS Tiger Moth with a Pico fight pack. I am curious, what is a JST connector?

Please can you tell me the absolute maximum value for the supply voltage for a "PICO F STD" servo?

Please be advised the absolute maximum value of "PICO F STD" is 8 micro second. We would suggest you to use 5 cell (6.0V) battery pack.

As one of the retailers of your kits and accessories, we are in need of a CHEAP transmitter to go with planes like the Pico stick etc. Many young people want to buy them but the transmitter is expensive and a simple 3 channel would do to keep the overall price cheap so that they can buy the whole system.
Please consider this point as it is costing you sales to new starters who are attracted to your good cheap models but put off by the price of Futaba and JR transmitters which are necessary.
I think your models are great and I fly and demonstrate with a Pico stick and Tiger Moth at present both indoor and outdoors.
Soon I will build the J3 and Fokker so I will be showing and flying 4 of your planes which think are the Best Value for Money available. I sell a lot.
Please advise me if you do make a transmitter. Also from an USA magazine I am told you are making a receiver +2 servos in a "brick", weight about 13 gms. This should be great! Keep up the good work!

We are now under development of the 4 channel transmitter. This transmitter will be under the mass production by end of October or beginning of November. Please check with us by end of October.
