Unless the pilot is nekkid I don't know why it would be moderated. If the YouTube is a public post, even the original poster has no right to say No.

I am going to have to call 'shenanigans'.

In fact, I just took a brand new HK receiver with separate sat, and bound it to a new model in my Dx8, since I'm putting my Sbach together this very evening.

Interestingly, the satellite bound independently and first, with the Dx8 display acknowledging it, and only then the main receiver did it's own independent bind a second or two later, resulting in two separate LEDs on.

I think that one little observation handily dispenses with two ideas: that there is no radio actually operating in the satellite, and/or that the main receiver somehow ignores that input or otherwise does not take advantage of it.

I again invite anyone who has information that the HK receiver somehow is not enhanced by adding the satellite to provide some sort of data or links or other confirmation of that rather odd claim.

Let's please operate on facts; and not operate in the domain of unsubstantiated tarring with rumors and/or vague unsupported innuendo.

Please do not accuse me of either, the advice I gave was in genuine interest, and good faith, I have no reason to tarr a product that is obviously endeared by a good few.

Test of satellite diversity function on Orange 6-channel receiver (1 min 48 sec)


Now watch this one,

Test of satellite diversity function on Orange 7-channel and 9-channel receivers (2 min 0 sec)


A bit confusing at first but food for thought don't you think. Have a look at some of his other tests and you'd have to agree he appears to know his stuff and is not really biased either way.

My own experiences at my club with these receivers have been non conclusive in that some have failed and crashed models and some are working fine. The 7 channel seems to offer better results, may be worth a look.
I use the manufacturers branded receivers with my radio, purely because I like them and to date they have not let me down, it is always your decision to use what you wish, in any way I wish you and all modellers a happy flying day

I couldn't believe it either until I saw it, for what its worth I only use orange rx on smaller disposible models, on my good stuff I stick with spektrum for the piece of mind.

Two comments:

1) I am not convinced his protocol is really testing what he thinks it's testing. Binding the sat to one freq pair and GUID, and the main receiver to a different code and pair could easily simply be an unanticipated and unaccounted for state that the design is not going to handle! For instance, I can imagine a scenario where memory of the channel pair and GUID hash is relegated to the main box, and if the satellite independently is using a different GUID hash and or pair of channels, that it is simply not going to operate correctly.

(How does he go about establishing bind on the sat without getting the same binds on the main? Whatever process he is using to do that could account for the irregularity he observes, for all I know....)

2) An additional possibility is that he simply has a single bad or defective main 6 chnl receiver, given that the claim is that his test 'passed' on the 7 and 8 chnls he had. I have no way of knowing what his intent was, or how many of these he tried his experiment out on.

At a minimum, he should do the same thing with Spectrum receivers, and then with multiple HK, and then compare outcomes. (Of course, it's possible he did this, but from the minute and a half video, without explication, it is not clear what the real intent or scope of this is.

It's certainly not enough to convince me that the satellite on a 6 chnl HK receiver is not providing the expected signal diversity when used as intended.

A far more realistic test would be to bind and initialize as usual, and then shield the antennas of the main receiver with shielding material, in order to simulate a bad signal condition, and see if the satellite then 'picks up the slack' and keeps things working until the main receiver comes back on line.

He binds both to one radio then disconnects the sat and binds the main to the other radio.

Although this doesn't directly check the diversity as the previous video it do in my opinion confirm the function of the satellite receiver:
Range checking HobbyKing Orange Satellite Receiver on Orange RX Receiver. (7 min 22 sec)


Without knowing how the pair, main and satellite reviver is designed to operate as tracknoob I'm somewhat suspicious to the test done in the previous video.

Then is something wrong with this 6 channel Orange RX. Maybe a non working sat port or a lame orange sat. A Spektrum Sat has a greater range as the Orange sat. Without a sat or a second activ switched antenna (AR400,AR600, AR6115, AR6255) have you a null spot and this is when the RX antenna points in TX direction.

Some typical systematic errors a shown in this video.
First point the TX antenna straight forward to the RX.
Then shilding the experimenter both RX with his body.
No wonder that with more extension the shilding is lower or absent.
This caused then the more range.
Then is that ground range on asphalt.

My point was to show the satellite antenna indeed made a difference, which it did.

He actually states he has tried this on multiple HK receivers, his other videos go into more details on range and reliability testing on other receivers, but as you are contesting the test methods, perhaps you have documentary evidence of your tests?
The reality of this is also irrelevant, as if you are happy flying this type of setup then carry on.

The orange receiver I saw failing had just passed a range test far in excess of 50m, a distance I was amazed at, and by the way I performed the range test.

I wholeheartedly agree the only way to find the comfort zone is to listen to opinions do your own testing then achieve your own conclusions, the only way I can dispute the claims is to make my own test which would involve purchasing a set from Hk perhaps if you have one you could do a quick test for us if you know of an efficient method of shielding a sat, I for one would be very interested in the results
In all accounts I wish you and all modellers a good days flying

There is a thread for these receivers, this is a Spektrum DX8 & DX10t thread.

Yes, it's also a thread for GENUINE Spektrum products, not clones and counterfeits. Use HK's free telephone support line if you need help with their stuff.

Just had my right stick fail under heavy set spring tension. Transmitter is just 6 months old. As an engineer I can not for the life of me understand why this part is made of plastic and not aluminum! It takes every bit of the spring load. There are lots of places in the design that plastic makes sense but this is not one of them! Nothing like flying a $1600 airframe and having your right stick go as limp as a dead fish...

Just sent an email to Horizon about a warranty repair. Time to see how good their customer service is. Although without some kind of upgraded aluminum part to hold those springs I don't see how I can ever trust this transmitter again. I was extremely happy with the DX8 up to this point. I hope they get it worked out so I don't have to switch everything over to another brand.
