spectrum newbie!

[Reckless]

okay so I just received my new Futaba FASST 2.4 6EX a couple days ago.. I'm "done" oggling and playing with the switchs after yanking it outta the box... now it's time to switch my boats over .. but I have a few questions

adding new receivers to the system... most of my boats are just 2 channel setups ... can I use the FASST 2/3 RX's ? theres nothing in the manual that came with the radio about adding new receivers.. I assume theres some form of programming/sequence so the RX knows which TX's it's looking for for each Model setting/memory?


my other question is a little weird... I'm working on building a big crane barge ... but I wanna run the tug and the barge at the same time from the same remote.... 2 channels to the springer.. and 4 channels to the crane barge... will the spectrum system send signal to 2 RX's at the same time (I assume they would both have to be programmed at the same time to RX to look/talk to them both? )

any help out there?

The whole point of 2.4 ghz is to find an unused frequency to operate your model on. Using two receivers is not recommended. If you had two of the same x-cvers active, the radio transmitter will go looking for another unused frequency to avoid conflict. I'm assuming you're speaking of simultaneous operation, which probably would not work. IF you intended to run each model separately, then a receiver for each model would be fine as long as one of them is shut down. Can't run 'em together.

As to your first question, I'd say yes, you can use their 2/3 channel xcvrs since they're all 2.4ghz. With that sort of radio, you can also program each model's unique specs into it that the radio will pick up when everything's turned on.

You dont have a SPEKTRUM lol

Im not sure about the futaba but with the Spektrum set up you can switch models while/when another one is still on, ( the one you switch from gos into shut down mode and just sits there )

I do not know if the Fasst set up will let you do that...

well this is what i'm trying to figure out is how to get multiple RX's 'tuned' to this TX .. if I can't run two at the same time that's fine I'll just have to figure out another way (like a umbilical for 2 channels to the tug for while it's tied to the barge... or just make the barge powered on it's own... was thinking of saving costs of another driveline LOL)
I know the RX and TX have to be programmed to look for each other ... the TX doesn't just look for the nearest RX and grab it... or there would be utter chaos every time 2 or more people turned on their boats and radios with 2.4 ghz

and yeah I don't have a SPEKTRUM ... I have a spectrum technology radio :p

I think it would be a safe bet that there is a way for the Futaba 2.4 Ghz radios to 'bind' a receiver. Or, more than one receiver at a time. How? Beats me, I don't have one. But considering how these type systems work, there should be a way of doing it. Otherwise, how would you switch models (unless you switch the receivers too)?
Good luck. If you happen to stumble onto how to do it, how about letting us know?

Have you checked the Futaba website yet? Here's the answer (http://2.4gigahertz.com/faq/faq-fasst-q893.html) under the Futaba 6EXA 2.4GHZ FAQ. You can operate two receivers as the same model memory (MODL) position.

I just put it in my nirvana II (the stock radio glitched and wandered alot :( ) .. and I did 'stumble" across the way :D

turn TX on.. press ID button on RX and then find and code each other... for next RX switch to next model ID on TX (aka model 1 to 6 on this perticular one) and same thing.. then each one you add should be on that said model # on the TX... I'll have to see if you ID 2 on the same model # later :D

was looking around and it's almost angering that the 3 channel RX's are within $10-20 of the 6 channel RX's .. bah.. oh well .. even with the cost of the 2.4 stuff .. it's still a little cheaper then the radios I was having the purchase 12-13 years ago when I got out of it ;)

heh.. you were posting as I was writing... thanks! I was kinda thinking that was the way... I was just gonna try it and see.. but this is good to know... looks like I can rig up the springer and the barge to run at the same time.. excelent :D

Don't have experience with Futaba's 2.4 system, but I can afirm that the Spektrum will run 2 Rx's at once. I do that all the time when sailing the tug out to tow in the barque. Both boats are responding to 1 Tx.

Brooks is right...I have the DX6 in about 6 boats now and can attest that if you have two or more receivers on at the same time...they will all respond to the transmitter at the same time. I had my fast electric power up on the stand at the pond last sail by accident when I went to power up my sail winch in my Nirvana. I was lucky no one was handling the fast boat at the time....be careful out there! :eek:

Just to clarify the principle. When the Spektrum transmitter is switched on it finds a free frequency and sticks to that, transmitting its unique identity code GUID that was programmed in at build time. When the receiver switches on it looks for any signal with the GUID that belongs to its bound transmitter. It is the GUID which is memorised by the receiver during the binding process, not the frequency. Hence you can bind as many receivers as you like and later simultaneously use them.

Beware that the failsafe position is reset and memorized by a receiver every time you bind, so make sure the throttle stick is always where you wanted it to failsafe to for the memorised model if you use several receivers on the same model memory.

Futaba works similarly but has a continually changing transmit frequency.

I'd get very confused if I tried to use more than two channels per model, and no one has enough hands to use more than two models at once!

Good luck with the one man demos.

yes, with the dx6i you set up the safe throttle point when binding!! im guessin you do this for all the spektrums radios so if you loose signal or turn the tx off or switch model memory the throttle will go into the set safe point which should be neutral for your speed controler... though all the other stick positions will stay as they are when you turn the tx off or switch model memory or its looses signal...

if you do not set it up right and you turn your model tx off or something gos wronge then your boat will go at what ever power and most probley will crash :rolleyes: If you do not ever set this up then more than likely your model will go full power backwards as it would be set up for planes :)

read your manuals chaps...

now i would of guessed that if you had your 3 channel rx in your tug or what not, then a 6 in your barge you could just use 4,5,6 on the barge with ease then you would be runing 123 in tug 456 in barge

good luck though, yet you still dont run on spektrum lol yours is runnin fasst :cool: which is diffrent :p

[Reckless]

yeah the tug will be on 2 channels (throttle and rudder..) and the barge will have the rest of the channels.. for the crane.. so basically unless I need to readjust the barges position while playing with the crane I'll only be using one model at a time basically
