best dual receiver system

[sapca]

Hi,

What is the best dual receiver system ( for big scale airplanes ) on the market today.

I use futaba G3 receivers !!!!

IMHO By far, the new Duralite Powerbox system has dual redundancy for batteries and recievers. With this new system, both recievers are able to control the WHOLE plane. No more splitting two recievers between left/right sides of the airplane. (and it has servo matching built in) Call Duralite for details. Good luck!

Any will work fine, just run 2 switches, 2 batteries, 2 regulators, and 2 receivers.

Personal choice But I don't like a power box system. why have 2 switches, 2 batteries, 2 regulators, and 2 receivers run into 1 power box. Futaba JR hitec etc...A fancy power box has the same or higher likelyhood of failure as a receiver, then depending on how it fails you crash.

[Colonel Klank]

Not to argue, but Duralite has done their homework on all their systems and have a very high degree of safety and redundancy. The sheer simplicity and low number of components of the Powerbox, when compared to the complexity of the reciever, is staggering and your odds actually go up compared to an individual component system.
The switches are "Failsafe On" which means that if they come unplugged or are damaged in flight, the Powerbox continues to run. The regulator section is also failsafe and reverts to limp mode if a problem occurs, allowing you to safely land your plane with full control of ALL servos. If a problem occurs during flight, one of four LEDS mounted on the outside of the plane will glow red alerting you of that problem.
The Premium Duralite Powerboxes also eliminate separate servo matching devices, reducing connections, components and the total number of possible errors and is actually less expensive than component systems.
Whichever way you decide to go, a dual Rx setup has saved many planes.
Best of luck!

Well I cant sit back and be out done here.

Weatronics have a single box, dual receiver that runs with any TX (not 2.4 yet) 12 channels, fully programmable with system data logging on some twenty functions plus a built in GPS to give you real 3D readouts of where you went, how fast, how straight etc etc etc.
Automatic ganged servo matching, twin battery, failsafe switches to on, flashing super bright LED if you have an on board failure register on the system that you can see from a mile away, 24 servo channels totally able to be linked to any radio channel. Technically you could have 22 servos on one channel if you so desire.
Twin built in failsafe regulators, update able software of the internet so no obsolescence built in. As an example mine arrived as a 10 channel unit. Today it is a 12 channel unit, just upgrade the software. Switches between the strongest receiver signal in two milliseconds and I don't think you will feel it when it switches over unless your really quick.

Fully PCM compatible and with onboard failsafe for all channels.

There are some good options available today for the dual receiver preferences.

There are more coming as well but I cant say anysink!!!!! more.

I have been using a PowerBox for 4 years now. Not a single problem. There are many people that will argue their point of 1 or 2 rcvrs. When I first went with the PB, I switched to just one rcvr. Not that they have just come out with the RRS to mate up to the PB, I have chosen it to add the second rcvr back into the plane.

Many people what to say it is just another failure point. I don't see it that way. I consider it a help. My opinion. I have not had any issues with noise, hits or lockout of any kind. I too use the G3 rcvrs with no hesitation. I also feel that some people that have problems can usually look and see how they install their equipment as part of the problem. Again, just what I have observed over my many years of flying. I researched the PB equipment before buying it and I have never looked back at it being a problem.

As for needing 2 switchs, regulators, that is not the case with some of the PowerBox units. The switch as Colonel Klank states is a failsafe switch. It fails on even if it comes unplugged after the unit is turned on. The regulaters are builts in and the 2 batteries should be wired with a heavier guage wire mounted to a 6 pin plug giving you redundant battery hookups. Heck, if I line to a servo shorts on something, the unit shuts down that specific line with out the unit missing a beat to the rest of the equipment. Heck they even have ferrite rings to help with noise suppression to the rcvr. As for power to the rcvr, Every line between the PB unit and the rcvr is a power supply. They all can't fail at one time.

And now with their new RRS system for dual rcvrs. It is a big plus.

So..... Down side to the units....I see none.

Pics attached are of my old setup and one of my new setup.

Just my opinion.

I 2nd the Weatronic. All in-one unit, no wires running everywhere, less connections to fail, dual Rx, power distribution and regulators in one box. It does not dupport G3 but I run mine on PPM and set the failsfafe on the Weatronic itself. Best of both worlds fast, smooth PPM with failsafe.

Only drawback I see is don't use the servo matching on anything but an aluminum servo tray. A buddy of mine and I were setting up a Carden Extra 260 a couple of days ago and the servo matching mis-matched a 3-servo wing and blew one of the servos. Not nice.

The data logging and GPS features are awesome.

I have also have very good luck with Smartfly Super Regulators and Power Expanders. 2 of the Sport Power Expanders would work great in a dual Rx setup.

My only other problem with the Weatronics is that, unless it has changed, it only draws from one battery at a time.... it switches back and forth. IMHO this is too much stress over time on a single 5200mAh LiIon in a 40% (since at any given instant all current is coming from 1 of the 2 batteries).

I'm a K.I.S.S. guy. Leave the fewest failure points possible while providing the best redundancy possible.

-2 x Multiplex RXs (either 9 channel or 12 channel synth IPD RXs)
--These are great... tons of great features, IMHO better then any PCM RX out there.
-2 x Fromeco 5200s
-2 x Fromeco SuperReliaSwitches, 3 output leads each, 16 gauge input with Deans Ultra Plug, failsafe switch built in
--You actually can't buy these WITHOUT the switch... if you buy just the reg the swtich is actually still in the Motorola Reg chip... it's just always on... why add another switch in series???
-5955 servos... great servos.
--All programmed using a protractor for nearly zero current through the entire range of motion. See DOD videos for details. For rudder I love the SWB self adjusting trays... IMHO well worth the couple extra ozs... especially since I'm saving that same weight in Powerboxes, Matchboxes, etc... Expensive, but you'll have it forever.
-Choke servo.
--Motor won't die if the side of the plane the choke is on dies... this will happen with most optical kill switches.

Power distribution... each reg has 3 outputs that get plugged into 3 empty channels on a RX... each plug good for 3 Amps, so 9 Amps total PER RX, 18 Amps total. The regs and batts can barely keep up with that.

The ailerons are on homade harnesses... each servo gets its own power supply (unlike a Matchbox or a Y, just like a Powerbox) from the RX.

TX is programmed at 140% all around with 0 subtrim. 140% vs 150% leaves slight room for a click or 2 of trim if needed.

My favorite color... blue.

My pet peeve... "this worked for me for XX years." The term that comes to mind is: Statistically Insignificant. There are guys flying on 1 batt, 1 RX, plastic servo arms with unsealed hinges. Works for them for now... I'm not gonna do it. I use top notch proven stuff and as little of it as possible, along with a possible innovation or 2 of my own.

Cheers all and good luck.

Yes - the Weatronic only draws form the Batt 1 until it hits 6v and then it switches to the backup pack and lights the LED solid. I use a 5200 in a 35% and a 2600 as backup (overkill.) I prefer the way th Smart Fly Power expander switches. A 40% with 14 servos is gonna drain that 5200 and put a LOT of strain on it to be sure if you fly 3D.

I second that! The Multiplex IPD is excellent. Thats what I use in my smaller 30%-33% planes with a Power Expander, Super Reg and 2 batteries. I fin PPM much smoother and more responsive. With the Multiplex IPD or Weatronic you still get failsafe too.

[saflyer]

I like the weatronic, but power your rudder system via a separate power supply.
Take one seiko servo and poewr it with a 7.4 Lipo, the test can weatronic can handle.

On the other hand I've for Multiplex receivers in all my planes, except the ones that have got the weatronic inside.

Hi Joe,

That is what I'm looking for

Here on the German forum, they whrite not so good of the weatronic system.

I was thinking to by the weatronic,bud allot of people has transmitter range problems.

Can I use the RRS from powerbox together with the emcotec mini 6 ????

Hello Sapca,

I personally would not see why it would not work with the Emcotec Mini 6. If I remember my Mini 5 I had, it hooks up to the rcvr in a similar fashion as the Powerbox units. It is not like the PB units are talking to each out. It is just taking one output to a rcvr and splitting into 2 with the RRS system detecting the strongest receiver signal and constantly switching between them. I like the idea, myself.

[flyingklown]

I use two R149DP in my J'TEC 40% EXTRA 330L I used it in my 3W 40% all season last and the first this season. It has saved me a few times. However I have the 14MZ and have the G3 but I couldn't afford another one right now. But it would be cool to change to any channel I want. Other than that I like the alternative set up. I know a lot of people that use one RX. But for me it has to be two too!

Oh Yeah????? Well.........Does it slice AND dice?

Not to join in a debate I can't speak about from personal experience, but check out the Emcotec DPSI RV - or something like that. Built in dual regs for dual power supply - and variable voltage, and uses both receivers at once. From what I've read it's the most refined and reliable dual receiver system thereis, it's just a little pricy for my. I bought 2 G3's for my 12Z and Fromeco regs, batteries and switches before I found it. I just split my plane in half (guess which way?!?!) adn it works, but if one reciever quit I'd only have half the plane. The Emcotec unit would allow for full control on one receiver - that's a feature I would really like. I just couldn't bring myself to add up what I've got in the radio if I did that. OH, Dessert Aircraft is the US distributor, if that says anything.
