    SPMR9900 - DX9

    Q.) Can I transfer models from my other Spektrum radios to my new DX9?

    Q.) Which receivers are compatible with the Spektrum DX9?

    A.) Any Spektrum/JR DSM2/DSMX receiver or DSM2/DSMX Bind-n-Fly equipped aircraft are compatible. DSM receivers such as the AR6000/BR6000 are NOT compatible.

    A.) No, there is a new Rugged Design case coming soon for the Chroma, BLH8649 which will also accommodate the transmitter and extra batteries.

    Q.) I cannot get the GPS to lock?

    A.) You must be outside and away from all metal structures, including vehicles, building and furniture.

    Q.) How do I get Stability, Agility, AP and Smart mode?

    There are two methods to access Agility mode on the Blade 350QX:

    Method One requires extending the end points of the gear channel beyond 120%. This can be done on either end but will replace SMART or STABILITY with AGILITY depending on which end point is adjusted.

    • Agility

    • Smart

    • AP

    • Stability

    • Agility

    End Point

    Center Point

    End Point


    Method Two requires the addition of a program mix to select the 4th (AGILITY) flight mode.

    DX7 through DX18 (including the new DX6):
    MIX n
    Gear > Gear > 0% - 50%
    Switch: (MIX)

    Gear > Gear > 0% - 75%
    Switch: AIL D/R

    Activating the mix will allow for AGILITY mode if you're in STABILITY mode.


    E-Flite EFL7150 Night VisionAire

    Q.) My Night Visionaire will not bind or initialize.

    A.) The AR636 w/SAFE that comes with the Night Visionaire will not initialize unless the plane is sitting motionless on its landing gear. In this orientation the receiver is upside down (label-side down). If you are looking at the receiver when binding, chances are the plane is on its back and the receiver will never initialize label-side up.
