Should the gain plug go in Aux1 socket on the receiver, and if so, how do I get the Aux3 twist knob to operate that gain function. The Mode plug is in the gear socket and that works fine for on/off or 2D. Perfect. Now if one of you guys who understands the DX8 could please tell me how to get that twist knob to adjust the gain I will be home free. Older than dirt and still learning, sorta ! Tom
How did you finally solve the problem?
Details if possible. I am having the same problem.

The DX8 radio manual said in the switch select settings on page 15 that an auxiliary port can only be used once. That was the key, it can only be used once. In theory, I wasn't using Aux1, but being it was mapped to the flap switch it was already accounted for in the menu. The default has Aux1 mapped to the Flap switch and Aux3 defaults to the twist Knob. By inhibiting Aux1 in Flap it showed up as another option for the Knob, so I was able to use Aux 1 in Knob. Now it works as I hoped. To get a visual of what I was attempting to do I plugged a servo into the Aux1 port of my AR6115e and could see it physically moving as I twisted the Knob.That is a good way of actually seeing if something is working or not. Once I saw it was moving with the Knob I removed the test servo and plugged the gain plug into Aux1on the receiver and the twist knob worked to increase or lower the gain.. It's actually easier to do than it is to explain. Tom
Maybe I aint as dumb as I sometimes feel

Love this thing!

Love this thing! Just flew my YAK55 with the Guardian installed just ahead of the cockpit. Did some vertical hover in 3d ...works GREAT and I am NOT a 3d pilot but like to practice...

I like the idea of using a foamy to check this thing out. I'm putting one in the Tiger 60 I'm building, but nervous about it. I'll use my PZ T28 or Corsair as a test bed to learn the device and build confidence first. Thanks before the great idea!

Well done JayY and Andrew. Good to hear T-28 is a good model and particularly 2D mode in Guardian. That's what I am trying to achieve with Super Cub. As you know it makes spiral dive in 2D but 3D is ok.

Now I think I have been able to locate two problems in the Cub:
a. Elevator horn (original & ~7years old) was hanging by 1mm plastic. So a new horn installed.
b. Elevator servo (HiTech HS82) is also faulty. Replaced that with 9g metal gear servo. So hopefully it should fly in the way it did when I maidened Guardian. Weather here - snow + strong wind for all of next week.... :~(

BTW, I always carry rubber bands & sticky tape for such moments as canopy flying off or for any minor field repair. Super glue is another handy item to carry + spare prop.

Cheers

Are you using all the default settings on the G? If not could you please let me know what settings you used in 2D.

Calling all Spectrum DX 8 users

This is slightly off topic - acquired a new DX 8 tx and programming it for G. The issue I've is that elevator makes hardly any down movement. Servo rechecked - no issue with Futaba tx. So what I need to do????

Surprising tho, dx8 has no issue with rudder servo - the same make of new servo I used in elevator .

Any suggestion?

Cheers

Please to hear JayY your day was not wasted. I always carry two models with me. One to experiment with and the second one just to soak myself in the undiluted pleasure of flying

Cheers

Is the neutral elevator setting centered (sub trim). Be sure your throws are set to 100%. If those two are where they are suppose to be set, try turning up the gain. More gain = more throw.

@ tom smith
Thanx for supplying details of how to connect gain to the "knob" in dx8.
It saved my time in experimenting / shuffling through pages of the program manual.

This is why Ixxxx this thread and rcg.

Cheers

:
Hi Tom,
I tested servo throw without G. Yep, trim neutral and +/-100%. Thinking about re-binding ???
