DX8 and Fy91Q Dreamcatcher Config
 
Ok, I am at a loss.

I have gone through everything, or so I thought but still have no juice. Seems like the bind went well since I have all the correct lights.

What setup should I be going after with the DX8?

Not exactly sure what you are asking or what the issue is. Can you provide more details?

Well everything seems to be connecting properly. When I power the the DX 8, the proper lights on the transmitter are all going, but I have no control yet. throttle ect. Just sits there.

Checked all the switches and connection and they seem to be correct.

I think I am missing something in the DX8 settings.

Most multis require you to arm the FC and get the motors turning. Not familiar with the FY91Q but I bet you need to do this if you haven't.

Yes sounds like an arming issue. Is the Rx linked and everything look like it has power?

It may be an issue with the ESCs not initialization, a few quick searches seemed to indicate it was a common issue.

From what I have been reading that controller is always armed whenever it is powered, rather dangerous. So it sounds like it may be your ESCs not arming/initializing. You may have better luck here: http://www.rcgroups.com/forums/showthread.php?t=1408019

From the last page of the manual:

ESCs Not Arming
1. Many types of ESCs have an arming protection set up where they expect to see an
incoming signal as soon as they are powered up. If the ESC do not ‘see’ this input
signal, it will automatically inhibit the arming process.
2. Upon powering up, the FY91Q takes about 1 to 2 seconds to initialize. During this
time, signal is not immediately sent to the ESCs. Due to (1) above, the ESC will not
arm even after the FY91Q begins sending signal to the ESC.
3. As a result, the ESC refuses to arm.
4. To confirm this, carry out the following:
(a) Remove all your ESC red wire (positive) connection to the FY91Q.
(b) Install an external BEC (at least 3A output).
(c) Turn ON your Radio Transmitter and set the minimum to -30%.
(d) Power up the FY91Q and your RC receiver via the external BEC, but NOT
the ESCs.
(e) After the FY91Q initializes, power up your ESCs.
(f) Decrease your throttle to - 100 until the ESC arms.
(g) This proves your ESC has the delayed activation protection.

5. An easy set up to solve this is to have a two plug power up system. i.e. power up
your BEC first, before powering up your ESCs
