A few days ago I bought the HK Tempest, 800mm ws foam warbird which is fitted with an ORX 6 axis stab.

This has 2 settings, beginner and expert and tbh it is excellent. Hand launching in beginner mode sees the 'plane fly out dead level no dramas and switching to expert mode allows full aerobatics to be carried out. I've been so impressed with this stabilizer that I wanted to buy one for use in another 'plane but for the life of me I cannot find it anywhere. So if you know or have seen one of these please let me know.

The other good thing about this stab is that it is SBus ready so if you have an RX with SBus then it is simply a one connection job, but you can still connect up a non SBus RX.

Searching for this stab I came across another mini but this time from Radio Link

Looks like really good value for money and this one has 5 different flight modes (do I need 5???) but as far as I can see only has SBus input but that does mean that it acts as an SBus decoder as well. anyone out there had first hand experience of the Radio Link stab before I dive in and buy some?

I have CC3D boards in a couple of fixed wing models. They take a bit of effort to configure, but work well.

I know what you mean about setting the CC3D up Steve, but a great bit of kit. The thing that attracted me to these was the simplicity of them, no setup required, just PNP. The downside is that the rates on the ORX stab aren’t adjustable (well I don’t think they are - no instructions for it) and not too sure about the Radio Link one. The Tempest does fly really well but I would just like to tweak the ORX a little bit and you can’t switch it off from the TX but you can with the Radio Link one.

Hi Guys

Similar sort of subject. Recently bought one of these from Bangood. Price was the factor, nothing much to lose if it's nbg.

So, anybody used one, thoughts, opinions?

Notice the price has gone down even further. Should I grab another one before they're all gone?

Cheers

Jeff

Looks like a generic stabiliser type but it has got the gain control pots. I would test on cheap foamy before committing to anything of greater value but no reason why they won’t be ok.

It has been my job to test these units in flight these past couple of years for a writer in the USA.

The units from the past to the makes mentioned here have been quite remarkable.

For initial tests avoid your instincts to stick one in a 1lb model as these units really do show their worth inside

models 5 - 6 lb upwards

No William, that's the 'old' type.

Interesting point Dennis, but in the HK Tempest, 800mm WS, it really does make a difference.

This thread made we wonder what a 6 axis flight stabiliser is? (Given that I am in a 3D world of yaw, pitch, and roll).

I discover it is the combination of a 3 axis gyroscope and 3D accelerometer.

I think this means the gyro is detecting movement of the aircraft relative to itself and the accelerometer is detecting orientation relative to the earth.

If that is wrong please tell me.

You are not far off Martin, a 6 axis uses accelerometer chip whereby if you get in a mess, you can just let the sticks

go and the model will right itself if it has enough height and you can also select SAFE with a switch it set up that way.

No such luxury with 3 axis stabilisation, where you get 3axis levelling assist in windy conditions and never let go of

The sticks, but can always switch the stabilizer off for aerobatics

The ORX in the Tempest gives a SAFE (beginner) mode and an aerobatics (expert) mode but I haven’t yet found an off mode!

Ron,

AUX1 is the on/ off, and I don't know if you have a spare socket on the mini orx

You need an extra 3 pin connection

On some models, it says Gyro, and on/off plugs there

KOPILOT lite

This any use. Comes with a GPS for return to home and 'geo fencing'. Flying weight complete is 20gm(setup unit is removed for flying. Can use S-BUS or PWM o/p's from Rx.

Quite a while ago I bought a couple of the Orange stabs but they came with super sensitive pots and were useless. Shortly afterwards they changed these to presumably logarithmic ones. I have an ORX Rx/stab which works but I did not persevere with it, also a few CC3D ones in quads which are now no good to me since our landlord banned them but have not really thought about trying one on a fixed wing. You have rekindled my interest because I now have lots of small electric models which could probably do with stabs. I fancy that BG unit so may try ordering a couple at that price.

Just ordered 2. Don`t touch the SG90 servos in the advert, they are very poor copies and utterly useless.

@Denis - most stabs give you an AUX to control ON/OFF but it isn't mentioned in the brief destructions which are this:

Channel input: • PWM input: Here is the channel assignment and shown as follows. Ch 1. Aileron, Ch 2.Elevator, Ch 3 Throttle, Ch 4 Rudder and Ch 5 Flight mode (A 2 position or a 3 position switch should be assigned for flight mode selection) • PPM input: Plug the flight mode/SBUS/PPM channel input plug into your receiver which supports PPM out. Here is the ch assignment and shown as follows. 1. Aileron, Ch 2. Elevator, Ch 3 Throttle and Ch 4 Rudder. Ch 5 (A 2 position or a 3 position switch for flight mode selection) • SBUS input: Plug the Flight mode/SBUS/PPM channel input plug into a receiver which supports SBUS.

@Gonzo - I use the ZOHD gear and it's really good but what I like about the ORX and the Radio Link is the simplicity, oh yeah and cheapness!

Jeff C, amazingly my two arrived today, still awaiting a HK order after over three months.

The usual Chinglese to decipher. I now need to figure out how to assign the three position flight mode switch and a channel with a slider on a DSX9. I really like these Tx`s but flight modes always baffle me although I have a complex glider using them on a downloaded program.

I do like the reverse gain option so will see how I get on when I have time. There may be more about these if I google them.

Sorry Ron, have just seen this

AUX 1 is Channel 6 and can see now your unit has 5 channels.

Channel 5 for Martin's Mode Switch.

Martin, gizmos usually work with a clean On or Off signal,

So talk to someone about using a slider
