You're correct about BnF and model match although the DSM module for the Futaba mz can be modded to work, and you do have to confirm your model prior to transmitting. If you compare feature to feature though (you can download the A9 manual here:
http://www.hitecrcd.com/files/Manual_Aurora9.pdf plus the info on what was added in the last two firmware updates:
http://www.hitecrcd.com/products/air...ra9/index.html ) you'll see what I mean.
The current promo offer
http://www.hitecrcd.com/products/air...roraoffer.html gets you a free 7 channel RX and the option to purchase an additional RX for half price so with the discounts we're seeing, you can get the Aurora with 3 RX for around $400. Nothing can touch this for bang for the buck!
