RE: Aurora 9
I just purchased and recieved one last week. Finally had the opportunity to try it out on Sunday. I LOVE IT. Its got a very good weight, its super easy to program, extremely flexible. I got it with 2 Optima 7 recievers for $429, and it included a coupon for another free optima 7. Thats a 9 channel, fully programmable with 30 model memory computer radio, and three 7 channel receivers (a $180 value for the recievers alone). I flew 8 flights and only pulled about 30-40% of the transmitter battery. The transmitter is also compatible with 2S Lipo.
Also the receiver battery voltage is transmitted back by the reciever without any additional modules. A really useful feature.
Go for it.
