Full featured transmitter for a great price
The transmitter is great for its safety features with audio readout of voltages and other things while flying. If you want to get the ACCESS level protocols you need to have an ACCESS receiver to bind it to, but it can bind to older ones as well. Updating the software can be difficult and confusing but is necessary for full function, so I'd definitely recommend ordering it pre set up with an SD card so you don't spend hours trying to do the software setup. Programming models and functions is pretty easy though, as long as the transmitter is working right.
