Has anyone used dual Spektrum receivers (AR 9000) as a redundant system? Or better yet can you? Any feed back will be great.

this thing allready has 3 recievers..
you need more?

Yes you can use this in a dual receiver system. Every reciever that is bound to the module will run at the same time. One of my flying buddies is using this setup in his 40% plane. I am using a single AR9000 with 2 satalites receivers. We are both have great success with the system.

Hi Tony,
Will you be running 2.4 in the Flash ??

I am using 2-9000's in a Carden 40% Extra. Took out the dual PCM's and installed the dual 9000's in their place. No issues at all, just bind them all at once.

I have the flash programmed on my 12Z not my 10x. So it is on 72mhz. I am using 12 channels so I would have to add equalizers for my flaps and elevators and nose wheel to put it on a 9 channel receiver.

Whatever... you only need 7ch to fly that jet...ha !!!

I was pretty sure it would work but had never tried it. I do appreciate the feed back. Digitech I was not using it for more antena purpose but only to split the load on the reciver.

I have 11 channels on my 9000 system. The ElectroDynamics gear management system gives me an additional 2 channels. Didn't have to change a thing with the new F-18, and the Predator.

Thanks Rob

I posted some photos of my setup in one of the JWM threads... working great in several planes.... I like using all the Rx's in complex aircraft. Great Data.

Wouldn't you be better off using a Emcotec or powerbox if you want to reduce the load on the receiver? From what I read if you have a voltage collapse, these receivers reboot. Might be cheaper than 3 receivers as well.

I had used a powerbox once before but had a failure with it so I am a little gun shy. I have never used a Emcotec. I will check it out also. What I had planned on using is two of the AR9000 recivers with dual Fromeco regulators the dual out put ones and two Fromeco 5200 mah battery packs.

I am assuming that adding a second receiver slpits the load in half but that may or may not be totally effective in maintaining the proper voltage to the receiver, depending on how many servos you are using and other factors. It may actually increase the chance of having a fail safe since you now have two receivers that might go into fail safe and need to re-bind instead of just one. And, the reality is that you are just guessing whether or not you will have resolved the real problem, which is voltage drop. I think adding a second receiver may be more of a band-aid than a solution.

Duralite explained to me that simple regulators do not have a sensing circuit in them and therefore do not have the ability to maintain the correct voltage if you get a heavy temporary load. This can easily be seen using an in-line voltmeter such as the Hanger Nine unit and operating all servos at once. You will be surprised how much voltage drop you will see if you perform this simple test. I could see over half a volt with just two digital servos. Fromeco regulators may have sensing circuits but probably not...According to Duralite the best way to maintain the proper voltage all of the time is to use a Powerbox or similar unit that actually has a built-in voltage sensor.

I run my F-16 w/o a Powerbox but it only has two digital servos (tailerons) instead of seven like my Bandit which has over 50 flights now with the DX-7/Powerbox combo. My solution for the F-16 was to use a 6.0 volt regulator instead of the 5.1 volt unit I had been using which would let the voltage drop to 4.5 volts under a heavy load on a brand new fully charged Li-Ion pack. With the 6.0 volt regulator I still see 5.5 volts even if I get a 1/2 volt drop..Gary

Gary, are you using a 6V battery or lithium 7.4V?

I would worry if you are gettting a .5volt drop with the lithium. With my Smart-fly sport plus Power Expander/regulator that I am flying I can pull 15 amps without seeing a voltage drop on my Cvolt that is plugged into the servo output. This is with 7.4v lipo batteries.

The test was done on a 35% 3d plane with 8 JR 8711 servos. There was a H9 inline amp meter inline.

They are 7.4 Li-Ion packs and the voltage drop I see is on the F-16 using regulators only (no Powerbox). There is no voltage drop on the Bandit where I have the Powerbox installed. If I am not mistaken the Smart-Fly is similar to the Powerbox with a built-in sensing circuit. Yes? Gary
