I was looking at a few different receivers and some have a satilite port. What is that? Is it so you can plug in more stuff? Like retracts and bomb droppers, flaps and so on?

Satellite receivers are for signal redundancy. They're placed on 450 or bigger helis so that the signal is secure at greater distances, in any orientation.
If you want extra channels for retracts, lights, etc., there are 8+ channel receivers. But of course this requires a transmitter with that many channels as well.

You're right there Nick,
I use Satellite receivers on my big planes, 1.4M span and above. Not really necessary on a helicopter or small plane, they do not get so far away. The big ones can be seen at a much greater distance and so are more likely to get out of range. I always set the sat & Rx aerials at 90º to each other so that one is always in a good position to receive the Tx and is not blanked by the motor or ESC. So far - works geat.
Tom.

OK, I get it. They're just a sorta safe guard for range. Cool. Thanks guys?

Ok,
So I got ahold of a couple of those little orange recievers and am confused as to the channel numbers. I am replacing a Flysky 6ch receiver and the channels are numbered while the turnigy rx is labeled like throttle aileron etc. Is there a standard for translating these so I don't smoke something? Thanks in advance,
Kent P.

Hi Kent,
I've tried to find out for sure, but had no luck.
However, the standard numbering for 6 channel Rxs is:
#1 = Aux 1
#2 = Gear
#3= Rudder
#4 = Elevator
#5= Aileron
#6= ESC
#B = Battery/Bind plug as required
Hopefully the Flysky 6ch receiver will be the same.
If you start by plugging a 6V battery pack into any channel and a Bind Plug into the Battery channel, you can bind to the Tx. Switch everything off, power up the Tx and plug the battery to the battery channel.
Now plug a servo into the other channels one at a time and see which stick/switch moves it. There should be no risk of a burnout.
If you need to make a battery pack, I have a JPG here of my construction. (Needs 4 rechargable AAAs and an old servo lead, no signal wire.)
Hope this helps some.
Tom.

That's what I needed tombo242. I saw this on another thread and did not wright it down any where. I also like your battery pack and method for finding out each channel. I got the receiver hooked up and lifted off a little while ago. So some trim work and I'll have all three of my birds on the same tx.
Thanks,
Kent

I clicked on the confirm order button and the only thing that happened was I got an email that said I would receive another email confirming my order. Thats not how PayPal works. I usually have to log into my Paypal account to confirm it and pay. This time nothing. No email either. Guess I'll give em another day and see what happens. I did get an email from thinkRC that my Big Lama is on the way. Step one.

That can happen if the item is not in stock .... "backorder" .......
Very few people even consider Backorder items as you have no idea when they'll be in stock. Second if you include a Backorder item in your basket - EVRYTHING waits till that item is available ... The simple answer is : Don't order Backorder items !
Some people say don't order if less than 10 items shown in stock ... I don't agree ... I've ordered when they show 1 or 2 and had no problem .... but you do run risk of another getting their order in first !
So go back ... check out your account listing on HK ... check out the item to see it's stock situation.
You can cancel an order by going Online Chat with sales ... I've had good response that way.

This is a hangover from early days of 2.4Ghz. The antenas being very short and the signal being a lot weaker than the old FM days -[ model construction led to shielded antena and loss of control.
In the old days opf long wire antena's ... we would think nothing of passing it down through fuselage and out at tail ... alongside control rods, batterys etc. etc. The only real concern was if real metal plate or carbon fibre was there.
In comes 2.4 with its short antena ... POW - models having control trouble because same set-up is not good. The antena needs to be clear of all metal and shielding.
The radio co's answer was to create a satelite Rx .. a smaller box with another antena that plugged into the main Rx. The idea being that you could now place main where best for servos and it's antena, the second in s alightly different p[lace and the antena as near 90 degrees to the first and clear of objects. Bingo - control was good and you could fly to hearts content. NOTE : distance and size of model has no bearing on this whatsoever - its the materials arouund the antena that is the decider.
But of course there were many models now of small size ... and two Rx's was a pain .... so radio Co's offered their rx's as single or with the second .... saying that as a single stand-alone - that would be a park range version ... ie ~300m. Full range being the twin setup.
Lets move on .... twin Rx set-ups are really a cheap solution and it needed someone to sort it out ... finally someone had the bright idea to dual antena a single Rx ... with brands such as FrSky having genuine listening on both antena ... accepting whichever signal is best .. The same advice applies ... try to rig antenas well away from shielding material and also have them 90 degrees to each other.
BEWARE : Not all dual antena Rx's are true dual acting ... and that includes some high-end brands !
Not many people know that a chain link fence is enough to degrade a 2.4 signal seriously and if you have distance in the equation - Oh Dear !
2.4 is really a line-of-sight signal ... unlike the lower freq. FM which has far greater distance and tolerance.
Final point .... the 2.4 Rx antena ... the actual working part is the short bit at tip ... not the shielded first part of the wire.
My iinstallations usually have one antena laying along fuselage inside, the other is passed through a small hole to "fly in the breeze"outside the fuselage. That way I know I am getting best possible pick-up.

I still haven't received my order yet and the orange Rx was not on back order. It just takes a long time to get an order from them. I ordered on 2/8/12 and as of today still no Rx. It does show the order as shipped. Long wait time is the price we pay for a lower priced item. I think if you dont mind the wait then go for it. But if you want it now, we have to pay the higher price. It's a choice.
I'll just keep waiting. Sooner or later it'll get here.
Tom

You're right there Tom, I've never lost an order from China yet, but sometimes they can take as long as a order from the States to come here.
A lot depends on the actual day of the despatch office despatching. It is not often on the day of acceptance, regardless of the despatcher! Patience - as they say - has it's own reward. In this case cheaper goods.
Tom.

Sorry - misunderstood ... thought it was delayed at HK.
I find that ebay is usually 3 weeks to me ... HK can be as long as 5 weeks ... and I have no idea why they take longer conosdering that they are shipping from similar location.

Generally FlySky follows the JR pattern on it's rx's ...
Ch 1 = Aileron
Ch 2 = Elevator
Ch 3 = Throttle
Ch 4 = Rudder
Ch 5 = Aux / Gyro
Ch 6 = Aux / Pitch
Power can be via any connection.

Thanks for the 'heads up' there Solentlife, a useful piece of info for those with that Rx.
