- 'Full range' (rather than limited to 'park fliers');
- DSM2 protocol (compared to DSM protocol, it gives better range);
- 5-point pitch curves and throttle curves (compared to 3-point on the DX6);
- Dual rates/ exponential on aileron, elevator and rudder (DX6 only has this on aileron and elevator);
- Better user interface;
- Servo monitor;
- Flight timer;
- Throttle hold.
The digital trims are known to be weak and can stop working. Spektrum resellers in most countries will replace these under warranty without quibble.
The scroll wheel is also known to be weak and can break where it enters the encoder. To reduce the risk of breaking, always press on the upper part of the wheel.
On some transmitters, model memories 9 & 10 share the same ModelMatch code, so a receiver when bound to one memory can also be controlled using the other. If this problem is present, the transmitter can be returned for servicing to have this feature removed; however, it can actually be handy (if used with care) when experimenting with setups for a new model;
Theoretically, as the transmitter is powered by individual cells rather than a tagged and soldered battery pack, some flying sites may restrict its use.
Some transmitters have a problem with the potentiometers reading the stick positions that can cause the output to 'stick' or 'jump'. The transmitter should be returned for servicing. See here. Some people have reported this issue developing without warning.
