How can I get the Version 4.x.x ProEdition upgrade with AttitudeControl (Rescue bail out)? What does it cost?
To upgrade your SPEKTRUM AR7210BX you need the latest StudioX Software. This allows to connect to the freakware Network and register your device to your personal account when you connect it to the computer. Then all available updates and upgrades for the device will be displayed individually.
Regular device updates are free of charge. For upgrades that enable new functionality we may charge some fee. You can see the prices and buy them directly from StudioX. Available upgrades and prices also can be checked at the product overview page.
Please have a look here if you need further information about the update/upgrade process.
