Multi receivers on 2.4

[Steve Mansell]

Hi,
just changing over to 2.4 gig. Bought a module for my Futaba ff9, and a matching receiver (Hitec AFHSS).
I have seen some installations using a separate receiver and battery for some functions to get round the problem of lengthy extension leads, or running leads up cabine struts to a top wing.
I have also seen expressed on forums difficulties in using multi receivers, as they cannot sync simultaneously.

How can I tell if the units I have can be set up with multiple receivers?

As an aside, are all 2.4 ghz receivers compatible/interchangeable like 35 meg was?

I feel I am always playing catch-up with technology, but then again having young kids helps 'cos its all easy for them!

Ta
Steve

Hi Steve,
As yet i haven't used a dual RX set up but i would imagine you would bind the first one then the other (Futaba). You also have to watch with Futaba that you have the right RX for the TX ie: FASST, S-FHSS, FASSTest. The newer radios cover all the different codes my 10c and 12FG only do FASST so the other RX's wouldn't work for me. In my Meister P47 i only run one RX and i have the elevator servo's in the tail, i use a SM Services powersave (split supply) with heavy duty extension leads. With this unit all the servo's get their twin 6 volt supply and none of the current goes through the RX, the RX has it's own twin 6 volt supply.
Hope this helps

Sean.

Thanks Sean,
I think for now I will go with the same receiver type that came with the tx module for most of my planes. I hadn't thought of split supplies, but that makes a lot of sense with long leads.
Cheers

Hi Steve, I've just fitted dual receivers for the first time, they're in my DC3. Due to it being over 20kg the main control surfaces have to be split, ie. right aileron and left elevator on one rx and left aileron and right elevator on the other, each receiver having its own battery and switch. My radio gear is JR DSX 9 tranny with DR921 receivers and I haven't noticed any signal "lag" between the two receivers, it's just as though the model was on one rx.

On smaller / lighter models you could split the model into two seperate aircraft with an rx, battery and switch in the fuse and the same set up in the wing. Saves a lot of time when setting up the model at the field and is ideal for bi-planes as you are not worried about trying to conceal wires up the cabanes. Hope this is of use for you. Jonesey.
