FMS reflex gyro

[slumi]

Hi mshagg,

yeah, the best is really you configure everything on your own.
If you don’t know what your gyro does exactly, then it’s better to take it out.
I will be looking for another product, which then will be another thread. I heard good remarks on iGyro from power systems.

[Straightshooter]

I'm not sure whys there's no mod range for gyro products. either really cheap or expensive like cortex or igyro.. however if the airframe is worth saving, then plan for the high end when buying the plane. putting trust in cheap products ends in disaster. out of control aircraft is a safety issue and. isolates our core principle of the AMA.

I'll call BS on this and just leave it at that.

Straightshooter xviper An old Czech saying, "I am too poor to buy cheap." IMHO that applies to pretty much any consideration I have when buying anything. Best, LB

Advise please, I am setting up my new 80mm rafale and have connected the sbus\ppm cable into the sbus receiver channel as per manual reflex say I can select any 3 position switch I am using the Futaba 16zx tx and a T-FSHH R3008 Receiver the remaining flying channel leads I have left unconnected as manual show these required for PWM only.

I bought an fms Reflex V2 gyro stabilizer to install into my fms 1400mm J-3 Cub. But I can’t get it to work. I first left the Reflex out and just connected my servos directly to my receiver. My receiver is a Hobby King RG15x. My transmitter Is a Spektrum DX8 gen2. With this setup every thing worked fine. But when I hook up the Reflex per the wiring diagram in the very brief instructions, nothing works. My first question is which way is the correct way to plug in both the input cables and the output cables. They can easily be plugged in to the Reflex in either direction. Should the input cables from the receiver show the yellow signal wire on top, or the dark wire on top? I have the same question on which way should the server cables be connected to the output connectors. I have plugged in the cables both ways but nothing works and the servers were totally quiet. Did I burn out something when I had the cables plugged in the wrong way? TIA

Hi, just purchased an FMS v2 gyro, does any one know if it will work in a Tundra1300 mm, I already have a FMS Kingfisher and the gyro works very well in that and the Tundra is very similar to the kingfisher.
I know that the v2 gyro is FMS specific but wondering if it is safe to use in the tundra

It’s a gyro and not necessarily FMS plane specific. It’s just what comes with them. If you know how to program it and know how to plug it in, it should work with any plane. I found the Reflex ports IN and OUT were confusing to me and even after testing, it didn’t do what I thought it was going to do and my plane crashed. I didn’t have the leads going into the proper ports going IN and coming OUT. I relied too much upon my experience with other types of gyros and the same understanding didn’t apply to the Reflex. I don’t trust the Reflex anymore but that’s not to say you shouldn’t as long as you take the time to understand how it all hooks up and have the correct programming for your plane. The Reflex generally comes pre-programmed for a specific plane, so if you put it into a plane that’s not in their list, you need to ensure that all the parameters are compatible with the Tundra ……….. IE, gains are OK, gyro response directions are correct, etc. The Tundra may or may not have servos that work in the same direction as in your Kingfisher.

I'm finding the reflex system is way too specific to an FMS product let alone a an FMS plane. Let me explain.

The reflex v2 I have came with my 800mm t-28. It is really a nice system, the plane flies great is high winds and is almost impossible to crash.

Now the bad. The system seems to be specific to FMS servos, as I swapped out for some hitec digital programmables. I had them laying around for years and they aren't cheap figured I would drop them in and revese them if needed. It all worked fine until I tried to set my endpoints and deflections limits.. the servos will only move about half of their programmed throws on all 3 reflex settings. Just to double check, I bypassed the reflex to the rx, and I had full throw back.

Sooo, something funky is going on there

Perhaps the frequencies don't match. Can that be changed?

[Jackdawack]

I would need to know what the output frequency of the reflex is. It claims to be compatible with all pwm signals, and I don't think there is anything I can modify on the servo end. I'm using HS 5065mg servos.

The Reflex family of gyros are specific to FMS planes wo be used with a standard with no other stabilization factory programed into it, i.e., Spektrum's SAFFE or AS3X. Those are the only receivers I am familiar with at present. The Reflex goes into a specific FMS model that you have to download the program for that specific model. It likely won't work in another brand airplane no matter how similar in dimensions they might be.

Masterguns It’s painfully apparent now that it’s true that the Reflex can only be programmed with planes that are on their (FMS) list. There’s some proprietary stuff going on there and putting it into a non-FMS plane or even an FMS plane that’s not on the Reflex list is not possible. I took my Reflex out of the Super Scorpion because it didn’t work right for me. I guess there’s no point keeping it as I prefer HobbyEagle or Spektrum in most of my planes.
I think people should understand that you shouldn’t be putting 2 gyros in series in any plane.

I have use the Spektrum DX9 with their AR620 rx. I've been learning the past week of toying with the FMS Reflex & The Arrows RC Vector don't work as advertised-at least with a non-Futaba tx/rx. I have no throttle response regardless of with servo leads to rx & gyro ports I try. Yes, I'm aware that the servo leads for a Spektrum rx re different than most other brands. FMS makes the Arrows line of models (as well as a lot of other models-even some HH planes...just to varying degrees of quality for the end product). Would it be fair to say that the Reflex & Vector are the tech as well? I'm confident that these flight controllers/gyro/stab would pretty well if they would even work with a Spektrum DSMX protocol.

S/F,

Has anyone had problems downloading plane configurations into the Reflex V2? When I connect by usb-c the Reflex led turns solid red and then flashes red very rapidly. None of the plane files will load. I've tried 2 different Reflex V2 units, 3 different computers and 6 different usb-c cables. I'm at a loss what to do. Any recommendations?

I don't know what radio gear you're using, but reading this thread from the beginning, there has not been many "success" stories with this Reflex device. After crashing one plane with the Reflex and nearly losing another and seeing a fellow flyer almost lose his Rafale, I've told anyone at the field who buys an FMS plane with the Reflex unit installed, to rethink that option. All these guys fly Spektrum and we've all gone to either the Safe/Select Spektrum receivers or to the HobbyEagle gyro. Based on this, my recommendation would be to tie a big rock to those Reflex gyros and drop them off a bridge. (Sorry, that's the only help I can lend with your download problem.)

Strange. I only have 1 data point, but I’ve had very good luck with the reflex on my 1500mm FMS P-51. Worked perfectly out of the box, and was very well tuned for the model.

Indeed. On this front, that's 2 Rafales and a Super Scorpion. The SS went by way of a trash bag. Both Rafales are still flying today but with no gyros at all. I think I've seen mentioned that even RC Informer did NOT activate the Reflex on his Rafale.

[Axel S.]

I have 2 models that came with the Reflex gyro and 1 I had to load from the FMS site. I had to get an app (bree zip file extractor), turn off my PC Matic internet security and it loaded once. Now I have been trying to load it for a week, 3 hours a night with no results. I get the plane list, but the grey area on the right that is supposed to show the version of the V2. It is now a paper weight. I won't be using it since nobody I know has ever had one. You Tube video shows a 1-2-3 easy peasy video that just won't work.

[xviper]

Curious how the 2 that came with the plane have been working for you.
