Guys

The new Powerbox Royal is out now, this features the RRS unit built in with 20 servo match sockets driven by 5 input channels.
The unit also has a plug in display that will show you which Rx is working best, the battery use for each pack and this display can be used during servo match. There are probably other features I haven't worked out yet!
Its the Daddy of back up units especially for our UK requirement of twin Rx's over 20kg

Its about a month late for me. I hope to pwr up my rrs-pbox tomorrow as build winds down. DANGIT it really looks cool!

That is awesome. I have used the Powerbox on alot of model and have always had great results. I can't wait to try this one.

Billy

Could you post link to manual or email it to me ([email protected])? It looks nice that display is a great idea. Do you know if there going to offer 1 with more channels?
Thanks

you prob dont need more channels(?)

my p-box and rrs only have 7. I run the hi-draw and essential items (primary flt and engine controls) thru them and route the rest (nose gear steering and smoke for example) directly from rx to servo, bypassing the rrs and p-box.

Won't that defeat the dual rx feature of the newer unit?

Also, anyone know the the methodology the new p-box uses to select which rx to use?

Hi Dave:

It's the Son of the Daddy of back up units but not the Daddy itself......I have the Emcotec DPSI Twin in my UB....it's been around for more than a year....dual batts, dual RX, line isolators and amplifiers, failsafe master switch, etc.....8 channels for servo control and uses 1 channel for failsafe detection and RX switching......can control up to 25 servos......

The more channels you have to route direct to the RX, the more chance you have of introducing interference....

I wish both Emcotec and Duralite would come out with 12 channel units thru the box....

On the servos you don't have going through unit how do you have them hooked up to both rx's?

1-Throttle
2-Ailerons (Y-connected)
3-Elevators (Y-connected)
4-Rudder/Nose Gear (Electrodynamics EDR-125 external mixer box) or could use Y-connector
5-Flaps (Matchbox)
6-Gear (EDR-125 gear failsafe so you can't put gear up accidentally on turn-on)
7-Brakes (Right Slider)
8-RX switchover detection channel
9-Smoker
10-Not used

This setup would work with Duralite Box as well.....you could actually get down to 7 channels if you don't use smoke and use the EDR-125 to do a down-elevator/brake mix....that way you get rid of brakes on channel 7 in the above example....but I don't like putting anything like a matchbox or EDR-125 between the elevators and the RX....

Seems to me Weatronic is even a better deal..

As it was explained to me in Jetpower fair, you lose a channel since its requierd for failsafe indication in PCM. The RSS will switch from one receiver to the next when the 1st receiver goes to failsafe.

Until I finally decide on 2.4....not quite ready yet.....I operate on 50 Mhz Ham Band......so that leaves Weatronics out for me.....

Not sure exactly how the RRS switches over....has been discussed in another thread......the Emcotec uses PCM or PPM......will switch with: Pulse exceeds Failsafe Threshold----PW<0.8 ms-----PW>2.2 ms---Pulse Spacing< 10 ms---Pulse Spacing >40 ms

you'll have rx backup on all of the important stuff, and be able to get back on the gnd w/ a bat or rx failure.
Do you really want backup for smoke and NG steer ???

You don't. I have 12ch running off of rx1 and 7 off of rx2 (the backup rx)

It's not the backup I am concerned about.....it is RF interference coming down the long lines in the UltraBandit.....even if a lead to the smoke pump or NG happens to be shorter, it runs close to longer lines, and may pick up some stray RF......there has been much discussion about the servo motors themselves generating a back EMF of suffiencient strength to cause glitches in the RX.......so it is best to protect all the lines coming into the RX.....

It seems that these Powerboxes, from all the manufacturers, were designed for Giant Scale Sport Prop planes, who were the guys to use them first when the Duralite PowerBox came out a few years ago.....and they don't usually need as many channels as Jet Flyers do.....I see no other reason why they would design a box with only 7-8 channels......

If Smart-Fly can do a 10 channel box, why not Duralite and Emcotec? Maybe size constraints as my 8 channel Emcotec is a pretty large unit as it is....

The REAL reason that Powerboxes have only seven channels is that receivers are designed and calibrated with at least two or three servos connected to them. If all servos were connected to the Powerbox with none to the receiver then the receiver would not be operating correctly.

PS Emmerich will be sending his latest units for description , review and practical test in RCJI. That said my Powerboxes work to perfection in my Mig 29 which has VERY long leads and a hydraulic system with asociated ECU and pump. Three minor system servos are comnnected to the rx and the result is a that I get unaffected range from the RX.

hm hadn't thought about that

How does a receiver know that a servo, Not a powerexpander/powerbox is plugged into the channels?

Hi Tom,

Time to whip out the credit card.

http://www.rcuniverse.com/forum/m_63...tm.htm#6389279

BTW I use the same Emcotec DPSI twin, with Futaba RXs on 6m, works great.

Smart-Fly Power EQ-10 for me. Built in isolators and matchbox on every channel.

I think U might be right, and if I weren't wanting to switch to 2.4 I'd have gone weatronic (?)

Another clarification (with apologies to Dave Wilshere) The Duralite Powerbox is identical to the equivalent Powerbox unit, the only difference being the labeling. Again, my source is personal conversation with Mr Deutsch. So if you want a Duralite 10 channel you will have to wait for the Powerbox unit !

As to how the unit tells that it has servos connected I haven't the faintest idea but I am more than happy to accept the explanation from the man whose company designed and built the unit which, like the Weatronics , ( I like THAT unit so much I now have three, working to perfection, ) works so very well for so many people, including my two, a programmable SC 12 and the standard 40-24.

I guess comparing the Powerbox with the Emcotec is like comparing BMW with Mercedes, both companies make similar superb products and each believes, quite naturally, theirs is the better !

David Gladwin.

Smart-Fly is a great product but it doesn't compare to above item in that it doesn't switch between 2 rx's. Smart-Fly EQ-10 would be even better if it was combined with the Turbo Reg to make 1 unit. I have used there Turbo Reg and Power Expander Sport combo and it was great, only complaint it wasn't 1 unit.

Tom this is the set up I've been thinking about for next plane although highhorse has got me thinking about his set up. I like idea of more channels. I have a Weatronic that is great but your still limited to 8 proportional channels in PCM-1024. Weatronic is tops when it comes to the data it provides you about plane. With set up below you get 10 channels all going through DPSI-2001 RV but no data like Weatronic provides.

Dont really know the emcotek line but the above setup sure looks a lot like my P-box setup. Two RX's feeding the RRS, which in turn feeds the P-box. If anyone wants to see it I'll take a pic of the setup and post it saturday...........

I'm brand new to jets, so all this fun hardware is new and sometimes overwhelming for me. If it weren't for the kind support in these forums I'd be lost!!

I heard somewhere that Weatronics is working on the 2.4 I agree the Weatronic has alot more features even though I like the fact that the Powerbox pulls power from both batteries at the same time. Oh well I guess that really doesn't matter. Can anybody confirm the 2.4 Weatronic deal?

Billy

How do you come to that conclusion ?
I have a full ten proportional channels from my PCM 10x (1024 or is it 512 PCM ??) with my Weatronics 10-20 (upgradable for free to 12 channels PLUS free landing gear programmer) and when my 12 X arrrives I will have 12 proportional channels.

What am I doing wrong?

Add 2.4 to the Weatronics and you have the ultimate RC avionics.

Regards,

David Gladwin.

Just double checked. S-pcm is 1024 with 10 bit accuracy, same as Futaba 1024.

Radio Futaba 12z is 10 channels in PCM-1024 channels 9 and 10 are only on/off channels. In PPM (FM) it has 12 channels but I haven't heard of anybody using Weatronics in that mode combined with Jet.
