The way you check and see if you have the update is to go to "System Mode List" and scroll to #83 "Trim System" then click on that and if you have "MOMENT" in the right top corner of your screen your good to go. You have the update.

HH called to let me know they upgraded the firmware in the TX AND RX! And repaired tthe stripped servos. Did'nt know the AR9100 receiver had a firmware upgrade. Hopefully my problems will all be behind me and I can get to practicing again.

Have you had the AR9100 for awhile?

Reason I ask is that those originally came out with the first version of Quick Connect which did not have the flashing light power brownout indication. If you had a brownout, which seems unlikely on one of the PowerSafe rx's, with the original firmware it just came back on in less than 1/2 second. The latest version has the rx lights blink if a power brownout has occurred.

I had my AR9100 upgraded along with all my other Spektrum/JR 2.4GHz rx's. As far as I know, that is the only firmware upgrade they've been doing.

Jon, you may have had a binding thing going on.

When you first Bind the RX the servos learn where their "home" position is. If you bound the TX and RX on a given model. Then started programming by turning on the 4 aileron servo setup and other mixes and Travel settings.

Then shut the RX and TX off. The turned it all on again...the Servos in their "home position" didn't know you had mixed them or "MATED" them in the device select and wing type menus.

The 4 aileron servo setup uses the GEAR channel. The gear channel is either full one way or full the other way. But your aileron channel is centered. So the initial Bind will set the gear channel to its "Home Position" but the aileron servo that is also connected will want to stay at center. The gear channel in and of itself can't be set to center when its the gear switch.

So once you setup the program in your radio you should re-bind to tell the servos where the "Home" position is.

I had this early on when I was learning the DSM2 systems. I had a model that every time I turn on the RX the gear would retract. Then 2 seconds later the RX would link up and the gear would come back down.

Solution is to re-bind once all your servo reversing and programming is done. Of the servos will try to fight each other on the Boot up of the RX.

My guess is this was your problem. I hope this explains it better.

I always start with programming the TX first. Setup my dual channels, and basic configuration. Then I bind the RX.

With each servo arm/wheel disconnected from the servo I make sure the servo is going the right direction and I attached the servo wheel to the servo. And check the travel. With multiple servos on a surface at these early stages its easy to have binding. So only allow one servo at a time on the surface until you are sure they are going to be close. Both rotation direction and travel, as well as centers. The hook up the second servo and adjust with the current meter like you did.


In your Case I think it was the need for a fresh bind once the servos were all setup.

I hope this explains it well enough for you.

Troy,
Thanks for taking the time to write an explanation.

My receiver obviously did not have the Quick Connect feature because it immediately comes on now instead of the 2-3 seconds it used to take. Sending the rest of my receivers in to get the upgrade.

Some one asked what happens to the DATA SAFE program when you get the upgrade on your TX. Well it resets EVERYTHING on that page to zeros after the transfer to the TX. Everything else was good. I went and re-setup the wing servos since they use different channel assignments and manually copied over my elevator info and I was good to go.

The picture at the top of pg 2 of this thread is only for TXs that have not had the upgrade. Upgraded TXs can using the wiring picture as provided by JR now. When I put everything back I noticed the adjustments on the balance page were happening on the same wing! Put the wiring back to what they recommend fixed me right up. And I rebound the RX after anytime I went into the TX and made a change!

Have 4 flights on it and will watch closely to see if all my issues are gone.

Right wing on ch 2 and 5...and left wing on ch 7 and 8. When your radio gets updated...it will reflect the correct rail1 rail2 and lail1 lail2 in the balance and end point adjustments. Having your radio updated is not critical...but the endpoint adjustments are not labled right..you have to map it.

pepatrick,

Did you ever finish your guide on how to use the balance function?

I would love to see a simple, but thorough step by step explanation on how to properly use this function.

I just got my 12X back from Horizon with the firmware update, and I'm ready to try to use the balance function.
I think I understand most of it, but I'm wondering how to set the mid points in the balance function. It's easy to set the neutral point and the end points, but how do you know where the middle points are, and how do you hold the stick in a middle point position while setting that middle point position?

I set up my servos as per the picture provided by CLM but the only thing that I can get to balance is the neutral point in the middle. When I click on any other point the slave servo does not move. I just spent 2 very frustrating hours trying to get it to work and nothing! What the h**l am I doing wrong. [BTW Horizon Hobby really needs to hire some better technical writers for the manuals] If I wanted to be so confused by radio programming I would have bought a Futaba!!

Someone help please!!

[Hammbone]

I don't think anyone really knows the proper way to use the balance function. I did get mine to work though.

Trumpetman, When you try to adjust a point, the stick position needs to be at that point for the servo to move. In other words, if you are trying to adjust the middle point next to the neutral point, you'll have to hold the stick at about 20% to 30% throw.
If you try to adjust the end points, you'll need to hold the stick at full deflection.
Where you trying this?

Jim

[Trumpetman]

I think that I was doing this as I was trying to get it to work. I will try it again however. Can anyone tell me what the abreviations stand for and why are the two points on either side of the neutral (middle) point tagged as "INH"??

Being able to access help like this from those who have actually made it work is great!

[pepatrick]

I will bring this back to life at some point. Here is the trick. Lets assume you are using 2 servos on each aileron. You will want to use 2 servos that are pretty close to begin with...This is not necessary but it does make it easier. Take the servo that the servo arm is as close to 90 degrees as you can get it without using the radio and use that as the slave servo (or outter aileron servo). Use the other obviously for the inboard servo. When you go into the balance function, you are matching the inboard servo with to the outboard servo. So...all adjustments are made to the master servo (inboard). The first thing I do is set the end points of both servos to somewhere between 125 and 150%. Usually I just use 125%...but I have gone as high as 150%. Then center both servos exactly. I use the HAN192 servo volt meter to make sure there is no binding. It goes inline between the servos and receiver. The I set up multiple rates..low 33% mid 66% and high at 100%. I make sure there is no binding at any of these settings (by using the HAN192 volt meter) and then do the same thing with the other aileron. I can get 5 x 12 minute flights on the Comp Super Xtra using 2 x 2300 A123 packs and still have 800 mahs left over in each pack. This has worked for me in 3 different planes without any problems. I will provide more detail in another write later (coming soon). Hopefully by the end of this week.

[Trumpetman]

Thanks Pepatrick! I'm hoping to maiden the new plane this weekend so I'm waiting (patiently) for your next post. In the meantime I'm going to get one of those servo voltage meters.

[Trumpetman]

OK, I have managed to use the balance function to set the aileron servos. All is good, no binding. But now it appears that the Differential function will not work! Do you have to set up Differential BEFORE using the balance function? Is there something else that I am missing here?? Love the radio but I want to shoot whoever wrote the manuals!!
