I'm considering buying a Royal Evo 12. I have a few JR PCM receivers that I would like to use with this system. My question is will the Evo 12 work with the PCM receivers (I don't care weather it's a PCM signal or not just wondering if they'll work)? Also, will I be able to program in a fail safe like I can with my current PCM setup? Thanks for your time.

The EVO will not work with JR PCM receivers, only a JR transmitter set to PCM will work with JR PCM receivers. On the other hand, you CAN program failsafe conditions into the Multiplex IPD receivers like your current setup.

I've been using Multiplex IPD receivers with my Futaba transmitter for the last 3 years, and personally think that IPD is a better scheme than PCM from any manufacturer. I also just bought a Royal EVO.

just my $.02

I really like the looks and the price of the Royal Evo, but I have too many receivers to replace (I originally got them very cheap). I was debating between a 10x and the evo as a replacement for my old 8103. The whole PCM/PPM thing makes very little difference to me though I think the fail safe is an important feature. I may still try an evo just for kicks. How do you like yours? Does it compare to the JR 8103 or 10x?

In the UK I know people who have traded in their Futaba 9C to get an Evo9, and heli fliers who are trading in the JR 10 for an Evo9.

I recently sold my JR8103 for a RE9. If you think that the JR8103 is ergonomically comfortable, then you've never held an EVO. Almost from the moment you grab the case, something sets off a bell. The screen is larger than the 8103 and since it pivots, it's easy to see. One of the beefs that I had with my 8103 was that you had to constantly adjust the contrast between field and shop. The EVO (while although it has a contrast adjustment feature) doesn't seem to be as prone to this issue.

The battery management function is almost a bell and whistle, but when you are able to glance at the screen and see an actual mAh remaining number, it makes flying a more peace of mind experience. The RE also has the typical voltage bar, but just seeing the mAh the the flying time field is a big advantage.

Harry C made a very good reply several months back on the www.rcgroups.com concerning the MPX line in general and I find that it tends to apply here in the US as he mentioned. He said that we're used to flashy ouside cases and shiny knobs and buttons and tend to make our purchases based on these premises. The MPX line is really more about substance than style, although I believe that the RE line is an indication of where MPX design might be heading in the future. So, the next generation Profi 4000 might still be a 'pizza box' or 'tea tray', but I'm confident that it will somewhat resemble the RE asthetically.

The best way to determine if the Royal Evo is an option for you is to download the RE manual PDF file and read through it. Once you have an idea what the features and abilities of the RE are, then hop on over the www.rcgroups.com and look at the Royal Evo thread. Harry, Bill and many others have input a lot of feedback regarding the RE and this will give you a real-world sense of what pilots are trying to do with the RE. You will find, though, that the RE is a very advanced radio expecially if your coming from an asian radio background.

Best of luck in your decision.

Thanks for the input joedydrulia. I'm starting to actually push my 8103 as far as mixes/bells/whistles/features go and will be purchasing a new radio within the next couple of weeks. I downloaded the manual and was really impressed with the evo. The only down side to the evo is that I'll have to replace receivers. I'm leaning towards the evo over the 10x at this point though, but I'm taking my time as I'll be stuck with my decision for a long time...

This is one of PCM's disadvantages, each brand uses its own system, even within a brand there can be incompatibilities eg S and Z PCM, so PCM does tend to lock you into one brand. No wonder the manufacturers like it.

Well stated HarryC

I too am starting to shift from PCM back to PPM.
Multiplex, Hitec, Polk and FMA are starting to really shine.

Some PPM systems are now employing fail safe (If that matters) and noise rejection algorythms.

Keep it coming .... love tech advances, bells and whistles etc..

Now I want Synth tx and receivers, plus frequency scanning, in my system.

Futaba and JR need to pick up the pace a little. You Think ???

I personally think that the PCM failsafe is not all that great of an idea. When you factor in a second or so delay in lockdown failsafe settings while flying anything close to the ground such as HLGs, helicopters and landing approaches on anything fixed wing, one second can be an eternity. I'd rather have the IPD and just take a glitch hit and immediately return back to control.

One thing (moreso here in the US) is that the EVO with the recent 1.26 software upgrade, has shift selectibility. With the senthesizer module in the EVO, you no longer need to worry about purchasing specific shift receivers on specific channels. This makes coming across receiver deals more of an option. With the synth. receiver module, however, (due here sometime soon) this will eliminate field channel conflicts tremendously and really gives you a great deal of flexibility.

I'm also going to purchase the scanner module since this also adds to the flight safety.

Oh, by the way, I installed the long sticks on my EVO as well as set the spoiler stick to ratcheting without spring tonight (about 5 minutes of work). Just for kicks and goofing off with a hypothetical model that I've been learning the EVO with, I decided to install the flight mode switch to the rocker/switch buttons on the front of the stick.

Took about 10 seconds to access the menu and confirm the choice. Works like a charm.

This really is a great radio. Perhaps one day when the force is strong within me (and the wallet is heavy) I'll move up to a Profi 4000, but then again, by that time, it may be called the Nimbus Profi 9000 XL.

joedydrulia I can see your point about the fail safe with older JR zpcm stuff, but the JR spcm receivers I have are instant (or too close to instant for me to tell). With a zpcm, I can turn off the transmitter (on the ground of course), then a half second or so later, the failsafe kicks in. The spcm does it as soon as I turn off the trans. I get control back immediately after I turn on the tx on both systems. I'm not trying to start an arguement, in fact I'm trying really hard to justify replacing all my receivers in favor of the evo. It's just that the PCM failsafe that I currently use works better than your estimates. For me, the fail safe be it from IPD or PCM eliminates flyaways and full throttle augering caused by rf interferance. It's still possible for both scenarios above to happen, but with fail safe they won't be caused by rf interferance. Just one less variable...

Speaking of fail safe, has anyone around here taken a hit on their EVO while using IPD? I'm curious to know weather the plane went googly or did the fail safe work as advertised?

Use of the Evo is irrelevant when using the IPD Rx since the Rx is totally independent of the Tx. I have used many IPD for a few years now (7 channel single conversion, 9 channel d/c and 12 channel d/c) with a Multiplex 4000. There are a couple of spots at our field which are known for causing a lot of glitches. On 3 occasions this year my planes have gone into full failsafe (1/2 second freeze then full failsafe) which I know has happened because my program is throttle goes to idle and everything else to neutral. One of those occasions was whilst doing a harrier, which is a bit heart stopping as the model starts to drop. On all occasions the control was restored in less than a second after the failsafe cut in. On other occasions when everyone else is getting serious and frequent glitching anywhere in the sky my IPDs just fly on through it unperturbed so I guess on those occasions the 1/2 second freeze is masking any very short glitches. So my experience of it is that IPD does the job well. Meanwhile we are plotting to blow up the nearby telephone microwave mast that we suspect is the cause of our problems!

Other advantages to having a Multiplex 12 (apart from getting 50% more full channels than a JRPCM10) are that: in 12 channel mode the Tx does data compression and the 12 channel Rx auto-senses this and switches into de-compression mode so that the refresh rate is higher than raw PPM, if the Tx is in 9 channel mode the Rx auto-senses that and switches off the de-compression; the 12 channel Rx has two independent battery inputs which are diode protected against cross currents between the batteries so you can run genuine twin batteries plugged straight into the Rx without the need for any other equipment like battery-backers. There is a third battery input which is not diode protected for use with single batteries.

Wow that receiver looks like it's got everything but the kitchen sink. Harry does this mean that I can use the fail safe feature with whatever tx? I take it that it will work with JR/FUT TX's. This would allow me to transition gradually to Multiplex.
