I would like to purchase the Aurora 9 but I want to move into 2.4ghz slowly. I have much on 72mhz right now.

I was hoping to purchase the A9 with 2.4ghz and also purchase separately the 72mhz transmitter module.

Is there an ETA when the 72mhz transmitter module will be available as a separate purchase?

Tried an experiment this am. There was speculation in another thread that there might be microstrip antennas on the pcb. Also it was stated that the second antenna on the 9ch was there for comfort. Remember the little pull out antennas on your cell phone? Nothing more than plastic rod to make you think you were improving reception.
Removed the antenna on a 7ch. Set up on a table with a wing from my Yak so I could see something move from a distance.
Lost signal after 34 paces. Got flaky at about 30 paces if I put my body between the xmitter and rcvr.
Replaced the antenna and redid the test. This time I got 215 paces. At about 200 paces it got flaky with my body between antennas.
In both cases I had telemetry up to the point I lost control. Really couldn't see the wing when I got out that far, but knew I was moving the surface as the rcvr voltage fluctuated.
As with most anecdotal reports, make your own conclusions.
I may try flying my foamy with the antenna removed and see how far out I can get.

I am still thinking if there is any evidence that there is absolutely no PPM output while a 2.4GHz module is pluged in Aurora...
Because there should be PPM in the trainer port, if someone want to use Aurora as a student unit in a teacher - student case. Or, if this is true... who stop you to use Aurora as a student radio, and use for transmission a standard FM radio, or an old style RF module, connected at the end of a trainer cable?

If you opened the receiver, you may have a look for a secondary antenna plug, maybe it is there anf just not fitted
Also, you may eperiment with a plain coax cable antenna, without any ORDA, you can get such cable fitted a good plug from any laptop, it is used for wireless LAN antenna, and is much lighter than the Optima antenna.

Unfortunatley we found out yesterday that some of the parts needed to build it have been discontinued so they have to re-work the circuit. This will delay the delivery of the Spectra PRO 72mhz module to at least Feb '10.

What you could do is get a A9 and slowly switch everything over to 2.4 and keep your 72mhz radio and still use that till you get everything switched over.

Excellent! And just so I'm absolutely clear, Synth ... you received a coupon for a free 7 channel PLUS another coupon for another (third rec) rec for $40?

Due to its size and weight, mounting of the BODA antenna is slightly less convenient on small models than the Spektrum solution IMO and I expect we will hear more stories about the "antenna was flopping around" as we have already see above. I do not think that properly and securely mounting the BODA antenna is hard, but will take extra care.]

Spectrum ar7000=16g
Optima 7=16g

Spectrum satellite rcvr=4g
Optima BODA=4g

Looks like a toss up to me.
I mentioned that I had a BODA flopping around due to a poor job of mounting. Picked up a used piece of sticky back Velcro off the bench rather than cutting a new one. Just lazy. Not so sticky. Re-mounted correctly. No more problems.

it's the same coupon. You check a box and provide your credit card info if you want the one for $40.

So If I buy the Aurora 9 / 9 channel RX combo in December, it should come with a coupon for a free 7 ch RX and an option to buy another 7ch RX for $40? If so, sounds like the deal! That should take care of my 3DHS 89" Slick, my 51" Slick and some plane-to-be-named-later? Sweet! Mike can you verify that I understand this correctly?

Thanks,
Jim
