I also have had a problem with loss of signal six times with the same plane . I do fly another plane for work using the Aurora9 I fly 5 hours a day. and have never lost signal with work plane. I believe it is a distance issue when the only time I have had a problem is when flying large scale P51 far away, thankfully after six times of lost signal six times with that plane I now fly it with a futaba 8fg with not even a glitch. Im now into hitec around with two Aurora 9's and multiple receivers and around $2000.00 in equipment. Not including the investment in the new Futaba 8fg I should have listened to my friends BUY FUTABA PROVEN OVER AND OVER..TO BE THE BEST!! (Posted on 11/22/12)

This radio has been very reliable not one issue here, I have used it with a 100 mph revolver 70, clipped wing cub 80" span,some warbirds electrics you name it the list goes on and it has been flawless this ''Unhappy" reviewer must be a noobie thats for sure. (Posted on 11/13/12)

I got back into RC flying and decided on the Hitec Aurora 9 after receiving a DX8 that was DOA. I do not regret my decision. The radio has worked flawlessly and the touch screen and menu layout make programming a snap. I don't have 200 planes and I don't own 3 of these radios but I am happy to report that the one I have works great and the connection so far has been 100% secure. I looked at the airtronics SD-10 as well, which is a great product, but ultimately was won over by the Aurora being able to do telemetry which has proven to be a great feature that I rely on a lot.

Do not buy it it is crap. I have three unexplained crashes with this radio system. Yes I was using the SPC with Life battery's and fully know what I am doing. The system stays on only 20 channels and will not change to new channels until a new scan is performed by you. The Airtronics radio system is a better system for a solid link. The Aurora 9 has nice programming but it lacks stability in it's link to the airplane. They spent to much time on features and not enough time on the reliability and a safe link to the plane. After all new updates I lost another plane and I am finished with it. (Posted on 4/1/12)

Serves my needs in every aspect. Love the update capability. I don't have over 200 planes electric glow and gas like Ron S. , but I like the radio. I think Ron S. is a hobby shop owner that has over 200 planes electric glow and gas in inventory, or is a rep for HiTec, or is a very lonely hobbyist with too much time and money. Over 200 planes? Do the math. 30 model memory for each radio equals 90 models...not over 200 electric glow and gas. Ok...so maybe Ron S. has more radios to support over 200 planes electric glow and gas, that he is not telling us about. Fine. Great. Ron S. is a braggert that really needs to sell off 1/2 of his hobby fleet, buy a Corvette and a box of condoms, then go out on Saturday nghts for a change. But then again he would be telling us about scoring on over 200 models...would he not?

I like my Aurora9. (Posted on 12/30/11)

This is the best general purpose radio on the market today.
I especially like the 30 Model memory, always monitoring your receiver Flight Pack Voltage, and capable of going backwards to 72 Mhz to accomodate my older radio planes - choosing any channel, any type receiver (+ or- shift).
I have 3 of these radios because I have over 200 planes - Electric, Glow and Gas.
