If you press bind button on K110, it turns off the LED and waits for the signal. On Orange it blinks and either binds - becomes green, or not - becomes red. On TX it's not a Bind, it's Re-init, I don't know why it is written "Bind" on it, I'll figure out. The S-FHSS does not have a specific bind signal, the RX just recognizes the signal as belonging to one of S-FHSS TXs and binds to it.

Great, I'm relieved. I need someone with original Futaba S-FHSS RX's to test it. Especially check the directions - I copied XK's, but am not sure they are correct.

Ok I need to define a model for the X350 ...

Coz it's strange ... I can invert motor rotation with hold switch (CH6) for me.. It should be when throttle is above or not 50%

5 - low (I set -100) is 6G (I don't know what this G stands for, I call it 6-axis), high (I'd set +100) should be 3D.

The protocol itself is AETRGP12 where 1 and 2 are two Aux channels. I suspect you can add 4 more channels but don't know does Futaba have more than 8 channel receivers for S-FHSS. The protocol temporal resolution is 6.8ms, spatial - 10bit or 1024 steps out of which less used - it's centered around 496, not 512 or 511. At least in XK's version.

They have R3008SB with S.BUS, but it's T-FHSS - it seems it's with telemetry. I found an interesting proposition on eBay - www.ebay.com/itm/Futaba-10J-S-FHSS-Helic...ver-MD2/281968812268 , but I really really don't need it myself - I have no models to fly with it. So, until next clone.

Ok what I need is when CH is 3D (the light is well turning to red), now I need to apply CH6=+100 when throttle is above 50% and -100 when throttle is below ...

I hope I am clear :)

CH5, not CH6. CH6 is pitch. And if you share this model file it would be great. I have installed the CC2500 module into unmodded otherwise Devo 7E, so I'm missing switches for full setup.

I think this is controlled by the return value of the protocol command PROTOCMD_CHECK_AUTOBIND

Nice work! Good protocol to add :)

Thanks guys! It's really encouraging to hear this! I will finish it up very soon.

I'm also interested in tests against Futaba's S-FHSS receivers.

Also, I'm looking at T-FHSS - does anybody know is it also CC2500 based? There is a deal now on eBay, it's very tempting, but a little out of my price range.

I will test in my Devo8s when my CC2500 module arrives. It will take a while...Thank you.

Used 10J for couple hundred. The problem is, after hacking it I have absolutely no use of it, and I have so many radios already - all these heaps of plastic, mainly toy grade ones.

I need expert in config file for the XK X's 3D quadcopter (X350 and upcoming X100, X251, X252)


First of all, we need basically only 3 2-way swiches : Th Hold, D/R, 3D/6G. I would like a basic config compatible from a 7E...
So Th Hold can be the HOLD1, D/R = FMOD1 and 3D/6G can be the lower throttle trim for example ...

In 6G, for the X350, throttle stick behaves normally: From 0 to 100, motors spinning always in the classic rotation sens
In 3D; here the lowers RPM value is at central throttle stick position. Above motor are spinning in the normal way (from +small_value to 100 I guess) and below motor's rotation is inverted (from -small_value to -100 I guess)


I hope I was more or less clear ...

I tuned a bit the config file forthe X350

HOLD: 3D/6G
FMOD: D/R
right yaw trim: Horizon/Accro


Can be improved of course ....
