You can set it up on it with no problem. I have even set it up on a 9303. If you had an 8 I would just send you the file I use but I can try and help you out.

Can you tell us what channels you have plugged into which ports?

Also are you using a NAZA?

I just set up my F550 with an AR7000 & DX7.

Some notes:

1. I used a heli program to start
2. 3pos flight switch controls GPS, Atti, Manual
3. Gear switch controls IOC but you have to choose which you want since it's only a 2pos switch. I chose Home Lock.
4. Throttle hold is failsafe - seemed logical from flying heli's

Failsafe with the TX off depends on the receiver using. If you are using a receiver that allows for programmed position then when you bind your receiver you can set this failsafe as well.

E.g. if you are using an AR8000 receiver when you go to bind the receiver, put the bind plug in place, power up the receiver, REMOVE the bind plug, set you transmitter in the failsafe active position (with your failsafe switch on and set throttle at least 25 percent), press and hold the bind button, then turn on the TX and begin the bind.

Easy

The transmitter will let you set anything that you want, depending on the receiver you may or may not have the option for a preset failsafe.

Some Spektrum receivers (and to be fair, some Futabas) will not allow a programmable failsafe position for anything but Throttle. You have to read the fine print when sourcing a receiver for these semi-autonomous systems. Failsafe is doublely more important to have right with these systems. You are much more liable to fly beyond radio range, and with auto-flight capabilities, a total fly-away is much more possible.

8J is a great radio choice. I have been flying a few of these radios on work projects. Great features and range for the money.

The old AR7000 does not support Preset Failsafe. You can only set a throttle position, all other channels just hold their last position - no good for setting Naza failsafe.

Mine is currently on its way back from Hobby Services for updating.

You don't need a new radio, just a receiver that supports Preset Failsafe.

Please tell me what model receiver are you using. Also which dx7 are you using as well since there are two different versions. If you don't get it sorted I will program one up since I have access to a lot of different things and can probably get you sorted

i should have got a rtf blade 350 or phantom untill i learned what i am doing before building one. i fly helis have not tried flybarless because im not good at programming so i knew this might be bad .im the type of person that wants it right before i start flying it.i try to take care of my things so they will last.

but this f550 programming has got the best of me very little info on dx7 setup to it most dx8,8j,.i have 2 dx6i i may try one of them but they dont have 3 pos. switch and are set up in helis at the moment

First, if your receive IS an AR7000, then you cannot program it for the configuration you need to have the DJI go into failsafe mode if the transmitter is turned off. The upgrade to this receiver, the AR7010 will allow for this, not the older AR7000.

So even if you were to get a newer transmitter, you will still need a newer receiver.

I will look this weekend at a DX7 to see if you can make the transmitter work (if you do decide to purchase a new receiver).

Also, if you do want to use the DX6, I can help you with that also and in fact may be a bit easier for you as I can borrow one, program it up with my hexa, then give you the settings. You will STILL need to get another receiver though

FYI - I mentioned earlier that I have the NAZA V2 running on my DX7 without doing any special programming. It would be nice if it had (2) 3-position switches but its definately doable without spending cash on a new radio. In fact, you only have to ship your AR7000 back to Hobby Services for the upgrade to the AR7010.

I chose to use the heli program, so I can't comment on setting it up in airplane mode.
