Spektrum DX7 dual receiver setup

[HuckinChikn]

I have 2 extra spektrum ar7000 recievers laying around and i think i'm going to use both of them in my 36% katana...the MAIN reason i'm thinking of doing this is because of the amount of plugs i have going into the reciever. This way,
i wont have to worry about not having enough outlets!

Well, I want to run just that setup in my 100cc composite Edge, but before I do, I'm trying it out on my Cap, and after I prove it here, I'll move it to the Edge. The setup was pretty easy, just bind them both and plug the stuff in. I made 2 little trays for the main receivers that I put foam on and velcroed them down (that's how you're supposed to do the main RX according to the manual), and used servo tape to put the aux receivers on. Everything moves the way you'd think, exactly like a single setup. For this, I just made a second lead coming off the switch, so it doesn't have redundant batteries, but that's fine, since it's just to test the setup before it goes in the Edge. Here's a pic of the setup, the 2 extra leads you see are for the ailerons, they're no plugged in because it's tough to take a pic of the setup with the wing on this old single piece winged Cap 232! Pretty cool setup, IMHO, since each AR7000 has 2 individual RXs, my Cap has 4 receivers now! I even turned them on for you so there's cool orange light bling in the pic.

here is my question.if you are to do a true redundant system why stop at this method. i understand the theory of splitting the plane in half to eliminate matchboxes. but if the left or right side fails you loose a control surface but the other works. still lost 1/2 of the plane.why not use 2 recievers 2 batteries 2 switches and use reverse leads and connect the control surfaces via y harnesses( naturaly you would have to make them as they would be reversed ends). this way if 1 reciever,battery or switch fail you still have full control of all surfaces and it is truly redundant.

Never felt the need, with the setup I used, the plane flies just fine should one side fail, it's just mushy. Also, if you were to connect the 2 sides together with Ys or something of that nature, now there's an electrical connection, so a short that takes out one side has the potential to take out both. Killing the redundancy.

FWIW, I've done away with the daul RX setup in my Edge for this year. I did it before because I didn't 100% trust Spektrum, now I've dropped it to a single AR9100.

lol thats what i wanted someone to say. as no solution actualy woorks 100% as thought out

I have a stupid question for you all. It says that the AR7000's Voltage Range is 3.5V-9.6V. I am running two 2600 packs on regulators at 6.0v. Am I overloading the receiver running two at 6.0v? Basically for some reason I am thinking I am running a total of 12v to the receiver. Please be nice.

You are fine. It's still 6v.
