Full HTSystem component reccomendations please.

Buy a Trinity head tracker. That plugs into your Dominators module bay. Plug your goggles into the back of your Spektrum and you will have a top notch head tracker ;)

I have now fitted a Trinity H/T in to my Dominator goggles and set up my Spektrum DX7s as follows:-

         In trainer set up. "Programmable Master" selected
                                    THR, AIL, EL, RUD, GER. selected to MASTER.
                                     AUX1 and AUX2 selected to SLAVE.
                                     Goggles selected to Ch6 and Ch7
                                      Pan/Tilt servos plugged into Aux1 and Aux2 of my AR7010 Rx.
                                      Cable connected from goggles to trainer plug of Tx.
                                       Powered up the goggles, Tx and Rx.
                                        Pressed trainer push button switch.

                                        No response to goggle movements, servos remain inactive.
                                         Tx main screen displays "NO SLAVE"

                                         Can anyone suggest what I have done wrong or what I need to do to get the head tracker to work. I am told that the Spektrum DX7s is compatible with the Fatshark dominator head tracker module.
Is there anyone out there who successfully uses a Spektrum DX7s with a Fatshark HT?

I`m not familiar with the Dx7 but don't you want your Tx as a slave not a master, so when you activate your trainer switch the Head Traccker channels take over your own ?

I believe that the way it should work is for the Tx to always be the master for the primary controls ie.  from the Throttle, Elevator, aileron and rudder but the slave to the channels which control Pan and Tilt from the Head Tracker. This is achieved on the DX7s by means of the Trainer Programmable Master facility, each of the channels can be set as either a master or a slave using this function.

I am coming to the conclusion that the cable link between the goggles and the Tx needs to be something other than the that used for normal training purposes. With this in mind I have ordered a Fat Shark Data cable which plugs into the multi way socket on the goggles and to the 3.5mm Trainer socket on the Tx. I am keeping my fingers crossed that this will solve the problem.  :detective:

Yeah thinking about it your right I think, lol not sure, oh my brain lol

I hope that when, or if, I ever get this darn head tracker to work I will get back to having a decent nights sleep!  :blush:

I have finally managed to get my Head Tracking system to work with my Spektrum DX7s  Version 1.03 transmitter. The Trainer function must be set to Programmable Trainer. with Rud, El, Ail and Thr. set to Master and Aux1 and Gear ( my HT channels ) set to slave.
The manual which comes with the Trinity HT unit is confusing to say the least. It does not tell you that you must use a 3.5mm Data Cable to link the Goggles ( in my case Dominator) to the Tx Trainer socket.
Powering up should be done in the following sequence.   
1) With everything disconnected from the transmitter an with no power to the goggles, switch on the Tx and Rx. Check that primary controls and operating normally.
2) Plug in the data cable to goggles and Tx.
3) Lock down the Trainer button switch.
4) Power up the goggles.
5) Holding the goggles horizontal and not tilted, press the HT button on goggles until a Beep is heard.
6) Check the correct movement of the camera in response to goggle movement.

Initially the pan was operating in reverse, to remedy this I had to go through the bleeping procedure which is very confusing but I eventually managed to get the pan moving properly after several hours. I think better/clearer instructions are called for here.   :confused:  :'(  :)

Glad to see you got it sorted :)

Seems a bit of a faff on to get it working each time though. How are you finding the Trinity ?

[acecall]

I am far from ready to fly with the Trinity, still building the model around it; a POLARIS XL with a much remodelled nose so that I can get a good largely unobstructed view of the ground below me and ahead when required. my first Polaris XL had tunnel vision making navigation a bit of a strain. The Polaris is very easy to fly being stable with a large speed range, Landing is a real doddle and of course it can take off and land from/on any smooth surface be it tarmac, grass or snow. It is also very cheap to make!

[acecall]

The last bit of the start up ensures you don't have to re-bind each time before flying.
I am very happy with the Trinity but I don't have anything else to compare it with.

[Coyote]

No I meant on the bench, whats its accuracy like, does your camera react well etc ?

[acecall]

The accuracy seems good, smooth and returns to centre as far as I can tell although I have yet to completely power up the camera and wear the goggles. I'll report back when I have done this.

I don't know if the dx7 does it as it's an older radio, but the feature you want was called selective master in my dx8 iirc


You can use that to choose which channels to retain and which to hander over.

As far as I am aware the DX7 is NOT compatible with the Fat Shark head trackers but the DX7s IS if is version 1.03.
I have now managed to get my DX7s working well with my Trinity head tracker and my Dominator goggles. Although I have yet to fly using the system.
