      That’s great NeoBot. We’re all hoping you can share details on what you did. Did you simply wire up the X4 TX to the T9x pots? I know. I violated your one rule. No Questions. :P

        sorry mate cant answer that as it was a team effort that some wish to remain secret :( but on a better note i modified another fpv build :D

        that was inspired by the pick of the bare frame with the brown credit card under it? posted here? i thought to myself it would actually be cool if hackmods could of had a quad small enough to ACTUALLY sit on that credit card?

        guess what i did :D then once you guess that you can watch the video and see that not only does it sit on a credit card but it also carries a full fpv setup too ;)

        now thats real

      On other flight boards, I found that if the Crystal is damage…it will prevent binding. I forget what the crystal looks like on the Hubsan… But on other boards, it’s a cylinder. So easier to replace. You may just need a new flight controller board. Probably the easiest method to get flying again.

      It’s also a great idea to double check that the X4 is fully charged, replace the transmitter’s battery with a fresh set, and verify that none of the transmitter’s buttons got stuck. If all else fails just apply for a refund if it’s still under warranty.
