Hey,
I've been puting my t-rex 600 together for a few months, and I am ready to buy the rest of my radio gear. I have a 611 for it and I was going to buy an Align gov for it also. I have the align 2 in 1 regulator. My question is, what receiver should I put in my t-rex, can I put in an eight channel or do I need the 14. I have a 14mz, I fly my jets and other planks with. I use my 9z for all my helis and this is going to be my first heli on the 14.

Thanks
Wes

I have the R608FS 8 channel in most of my birds. It has 2048 resolution like the 14ch, plus 8 channel slots and a power connector, so plenty of leads for external stuff.

I also use the R608/12FGH with my Helis, works really good.

I have the 7ch in my 2 evo 50,and they seem to work good. But if i had it to do over again i would have bought 2 8ch for the 2048. I'm building a gasser and i'm using the 14ch in it mainly because it came with my new 12FGH. I would get the multigov if it were me,i love the setup and how well they work.

Use a 608 or a 6014. Those are the only two that have 2048 resolution.

The added benefit of the 8 and 14 ch RXs is that they support full failsafe programmable in the TX, just like the days of PCM. This is a feature supported in the Multi-Ch mode in these radios. The 7Ch mode with 7 or less channel RXs only has failsafe on throttle.

with the price difference between the 608 and 6014, I would go with the 6014. You'll never know when you will want that 15 feet glider with 3 servos per wing and retractable landing gear. Plus, if you ever go scale, lights, retractable gears, switchglo, etc, etc all use extra channels.

my two cents

No argument there, I only own 2 608, but have 6 6014's. For the difference, if you have the room why not step up?

Erich, I am curious, what else do you failsafe? Why?

Failsafe settings on multiple channels are nice when you know what your're doing. For example I put my rudder channel to 0%. If it somehow locks out during a piro maneuver, the piro will stop. If the lock out isn't too long, it gives you higher chances to recover without loosing orientation and crashing. I also programmed ch8 to go to -100% on failsafe (I have the switchglo connected there) so in case of a interference, the heli will make a loud "beep" warning you that you have a radio lockout and not a brownout (its hard to distinguish between both conditions so a "beep" definitely helps you diagnose the problem).

my two cents

Tony

I haven't really thought about the stopping the piro idea, interesting, though I think I will keep mine in the hold position. I have found that most lockouts I have experienced were due to some sort of noise on the heli and as soon as power is removed, the vibration frequency changes and the noise typically stops...or at least changes enough for the radio to get reception back. I have had some "interesting" experiences whereby the heli was sort of sputtering across the sky as the radio would come and go (I had a pair of bad bearings).

Since switching to Li-Ion batteries, I don't think brown outs are very possible, and battery fail safe becomes useless since if I have dropped into the BFS range my batteries are toast and I have probably already lost complete power.

Good luck to you!

Regards, Guy

gnichola,
With your lockouts, are you talking FASST or Spektrum gear here?

Wes, the 608 is probably the best RX for the 600. However, if you want to save money go with the 617. It has all the channels you need. The channel mapping of the 14MZ and 12 series Futabas have eliminated the pitch channel lag of the old 1,2,6 setup. Also, it is not possible to tell the diff between 1024 and 2048 IMHO. I think most digital servos only have around 500 steps or less. As for failsafe, not really an issue much anymore with the reliablility of the FASST system.

I use the 6014 in two of my helis. It's a bit bigger than needed. But if you fly large planks, it may be the way to go for future uses.

1024 vs 2048, I can tell a huge difference between the two. When I first flew 2048 on my 3.1m Extra it has 8711's all the way around and it was like 2048 was made for digital servos. I then flew it in a friends heli, and it took a second for me to get use to. I have been a little busy flying planks, and bought a new 600 with plans of replacing my fury eventually also with a t-rex, but most of the people I fly with are still on 72...amazingly so I wasn't real sure.

Another question if anyone is still reading here.. I searched for the answer but I didn't find anything.

On the align 2in1 regulator is the switch just for the ignition or does it run both the rec and the ignition.

In all my prior li-po helis I ran the switch off the battery then the switch into the regulator to charge because you can't charge through the regulator does this apply for this regulator also?
(yes I know I need a step down for my 611 before I get flamed for that)

Wes, the 611 can run on the 5.7-5.8V it will get from the Align 2in1. The 9256, BSL251 and for that matter most digital tail servos are rated for only 4.8V nominal (a 4 cell NiCd pack). As I'm sure you know, a fully charged 4 cell NiCd pack will have a peak voltage of around 5.6-5.7V. So the Align 2in1 is not significantly higher at the start of the flight. You will see your servo wear out faster since it will have 5.7V during the entire flight, unlike a NiCd. I ran a 611 w/ 9256 servo and no step down in my 600E for almost two years without any problem.

You are correct. You cannot charge through the regulator.

The switch in the 2in1 is for both RX and glow igniter power. You have to press the button to get 15 seconds of fire to the glow plug.

With respect to the 1024 vs 2048 resolution, are you comparing your 9Z to your 14MZ? If so, the latency is far superior on the 14 and may be giving you the impression that the 2048 res is what makes it better. I have the 9C super and a 12Z. The 12Z smokes the 9C for the same latency reason. I fly in real time with the 12Z instead of having to lead the aircraft like with the 9C. Just a thought.

As to the resolution, I can not tell the difference of 1024 vs 2048. We need to understand that the resolution and latency is completely different term. Some people still think the more resolution the less the latency. No! It's simply because that Futaba's G3 made a great improvement for latency and they added 1 bit resolution from their renowned 1024. I use T10C-FASST and I both have R6014FS and R617FS. R6014FS is 2048 but R617 is not. But I can not tell the difference of the smoothness of both receiver.
