Is there a way to trigger an on/off switch to act with the throttle rpm range? Switch on, say up to 3000rpm ,off ,above 3000rpm.This is particularly useful when you install an on board plug igniter via this switch. I have tried throttle p mix with an aux channel in combination with EPA for the aux ch to limit itstravel but thisdidnt seem to do the trick. Any suggestions here. Cheers
Ithink you can set something like this using the fuel mix option in the radio. Go back to model type and tell it you have a fuel mixture so that screen appears under your model setup.
In this screen and the way the mix is working Ihave: (ignition is in ch.6)
H: 50%
L: 0%
ACC: +100%
OST: 0%
This gives me what apears to be a "on" for channel 6 ignition when at idle that then will quickly be off at about 1/4 stick travel.

Hi Lqaun
I'm pretty sure your overthinking the whole interferance issue. You have to realize that this is a frequency hopping spread spectrum. It will automatically change the frequencies within the active 20 channels in normal mode. You dont have to swich to scan mode for it to do this. Just do a range check in normal mode, then in scan mode, I'd bet there isn't much difference. I'd also bet that you havent actually had any interference glitches, your just paranoid.
I have attended at least a few pylon races with my radio and it is probably the most reliable there, there were at least a fewotherswho had DNS because they could not get their plane to bind when they got to the start line, (very embarassing). No such issue with aurora.

Is it possible with a firmware update that the radio can be made to hop over the entire frequency range so the scan mode is not necessary.

This behavior is not "lost bind".
What happened is when he turned on the transmitter it could not find 2 good channels available. When that happens what should be done is turn everything off, wait a minute, and try it again.
Rebinding accomplished the same thing, he waited a little while and some channel got freed up. But it wasn't necessary to rebind.

Let me ask you guys this... do you feel the Aurora is worth the money even if you didn't get the FREE and 1/2 price RX's?
Com'on guys, cut us a little slack, it's a FREE RECIEVER!!!! We're not talking a few hundred here... but multiple thousands that we are giving away!

Hi Gungadin
Lots of vendors have these RX'rs in stock, but Hitec's priority as to who they ship their stock to is irritating to say the least !
You took the words right out of my mouth

Thanks Brendan, How do you engage ch 6 in throttle mix action? I tried P mix throttle to ch 6 with values unaltered and went to the throttle mix menu and dialed your suggested values but it was not effective on ch 6 ! I am sure I am missing something here .Cheers

Yeah I feel the A9 is worth the money even if I didn't get the FREE RX'r. As a matter of fact not only have I NOT received the free RX'r but also I've NOT received the one I paid 1/2 price for back on March 24th. GEEZ OH MAN Mike what is it going to take ?

Hi........This has probably answered before but if it was I missed it..
How many channels are there for use with 2.4? dozens, hundreds, zillions?
Also, when you turn on the TX, where in the 2.4 spectrum does it start looking for clean channels?

RE: New Hitec Aurora 9-Channel 2.4Ghz Radio System
The picture below is the official Hitec service department fix for the well documented deadband issue on many Aurora 9's. I sent in my transmitter over two weeks ago, and got it back today. I had significant deadband on end of travel on left aileron, low throttle, and down elevator. The fix is the blue trim pots soldered to the stick pots shown in the picture below. The adjustments are sealed by what looks like hot glue.
The good news is the deadband is gone. The bad news is that the trim pots are not secured by anything other than their leads soldered to the pots. The main concern is the one on the aileron pot, as it moves with the stick. It is easy to move with the tip of my finger. I will likely stake it in place with some low temp hot glue.
I am somewhat surprised they didn't use fixed resistors once they determined what the value should be. The elegant fix would have been to replace the stick pots with ones within tolerance. I just hope these trim pots don't drift in value over time.

1. Settings Menu, System screen (picture 1): Select MDL Type > Acro> select "NONE" > Single Engine> "SET" > Retracts - Yes/No > Airbrake- Yes/No > Fuel Mix - YES (result as per picture 2).
2. Settings Menu, System screen (picture 1): Select "Channel", note Fuel Mix defaults to Channel 5. (as per picture 3)
a) tap "Fuel" > SEL and amend Ch5 to "gear" or other preference (as per picture 4) >then "SET" and return to Channel screen.
b) tap Ch6 "AUX1 > SEL and then "Fuel-Mix" followed by "SET" (as per picture 4)and return to Channel screen Verify Ch5 & Ch6 now show correct functions.(as per picture 5).
3. Settings Menu, System screen (picture 6): Select "P.Mixes"> tap "ACT" and screen appears. > tap "THRO" followed by "Fuel" > return to Programmable mix screen (picture 7) and tap "Select"
4. Move throttle stick to top position to highlight H: 0% and increase 50% . > tap 0% beside "ACC" and increase to 100%. Switch remains "NULL" (picture 8)
Servo in ch6 then will move a switch from On to Off as throttle reaches 50%.
If using a manual rather than an electronic switch and this method does not have servo throw for your switch, you may need to swap to a micro switch with lever arm which also compensates for excess throw..
5. Alternatesystems which save a servo and free a channel.:
a). Glow Driver - Simple On Board Glo Driver Use this system myself on large models. Switch is not essential because as motor speeds up, glow plug heats and draw from battery drops to virtually nil but increases again as revs drop and plug cools. This action can be observed when connected to a power panel glow driver and watching the amp meter as the motor is revved up and down.
b). On Board Ignition System

Is this ''deadband'' issue common to all A9's, or just the early ones? If so, is there a manufacturing date that would indicate when a fix was done for new radios before original sale?

RE: New Hitec Aurora 9-Channel 2.4Ghz Radio System
Well if Hitec would be good enough to tell us if it is a potential drift problem or a need for future adjust me, people could decide if they should find a fixed resister to replace the added pot. The problem is is it a variable and how close would the resister value tolerance have to be.
I am afraid to open mine...
Mayberry should be able to help with this info.

I was getting ready to go fly, but will have to wait to charge the radio. This is about the third time that I have accidentally left my radio on and totally drained the battery. I wonder how the guys with the Li-Po's are fairing with the transmitter?I'm sure there are a few dead Li-Po's out there from leaving the radio on.Time toquick charge...

In some of the programming set ups I see "ACC:" and "OST:" They are just mentioned in the manual but no explaination as to what they do or what they are used for. What are they and what are they used for?

ACC = Acceleration (for asymmetrical servo travel)
These are accessed viathe [Programmable Mixes] screen.
Best understood by setting up an Optima on bench and two servossitting side by side pluggedinto say Aileron &Elevatorchannels.(connect RXbattery)
Enter Settings>Model> [P.Mixes] > mix AIL<>Elev. Then apply 75% ACC and watch what happens when you move the sticks together and separately. Repeat with OST. Handy featuires.

Ithink it would sort it out because Iam pretty sure there is some type of code the tranmitter sends out at binding to a Rx. That tells the RX, "belong to me" Tells all the Rx that. Then the scan algorithum in the TX and Rx enables the Rx to know "where the Tx is going next in the scan/channels or what channels to use. Idon't know the details for the A9 system but Isuspect it works along these lines when in Normal mode.
Also, Idon't think the A9 system ever works on a single channel. In normal mode it always hopping over say 20 channels. Only God and some software guru in South Korea probably knows what they are. And Jack Bowers' guys could figure it out with a super duper scan rx and associated computer analysis.
Also, failsafe is probably a Rx memory function. You set the Tx where you want the controls to be if the TX to RX link is lost and the RX remembers those commands when you do the RX button push and wait 5 seconds on the Rx failsafe set up and goes there when the signal is lost for some time untill the link picks up again or they stay there till the plane "lands" ....crashes in the failsafe settings.
If you set failsafe for your engine at idle trim and then in flight or on the bench you moved the trim button way up and then turned off the TX the throttle should go to idle, not the recent trim setting.

True FHSS is where the TX sends with the information an IDcode for the Rx to recognise it, the command e.g. left aileron down right up, and the information about where to look (whatfrequency) for the next command. this is how Futaba works.
The Hitec in SCAN mode should followa similar methodology.
What I find puzzling is the need to rebind. Binding is merely the Tx telling the RX, "Hi I'm Tx model A218372 of 1.36x10^9 or something like that and the Rx is now recognises the Tx name everytime a command is sent. So the ID tells the Rx Hi honey I'm home followed by the command "Whats for dinner" Followed by the I'm going to be in the lounge reading the paper.
So now the Rx knows to deliver the dinner to the Living room.
However once the Rx is married to the Tx there should be no need for the Rx to unbind itself because it can;'t see anyother Tx's
If the Tx and Rx become unbound in the switch from Normal mode (single channel)to Scan (FH) then there is a design fault in the system.
Its like a wife looking for a new husband because the previous one makes more money!!
