[edit] Known issues
The transmitter is very 'bottom heavy' if hung from a neck strap; a number of devices are available to move the neck strap eyelet below the power switch, leading to a much better balanced transmitter.
A number of people have reported odd results when rebinding a receiver from a Spektrum DX6i to a DX7 on a CCPM helicopter. The fix has been to reset all CCPM parameters to 50%, rebind, and then reconfigure the CCPM parameters as necessary.
The countdown timer alarm will not sound unless the display is showing the main screen (i.e. no menus).
[edit] Hints and tips
The DX7 comes as standard with each gimbal supported by two bushings and two radial bearings. Some owners upgrade their transmitter to quad bearings, see below.
