I struggled with that choice a while back. I wanted telemetry if I could get it, and I figured I may get into full house sail planes.

A9 was on my short list, but I eventually went DX8.

Things that led me that direction: bind and fly planes, cheap orange rx's for little foamies, telemetry. I also like the vibration alert with the telemetry, and the Sd card. Nice to back up models, updates, and a buddy can e-mail their program. I also like their power safe line of receivers.

I do wish it had more mixes or flight modes, though.
