removed battery for 1 day and then reinstalled. Same problem. Does anyone know if there is a button or jumper switch on the motherboard to reset the system?

SOLUTION: I saw earlier in this thread where people had similar "throttle warning" error. They thought it was battery. So I charged my LiPo to full and tried again. Got same warning, but noticed that if I held the throttle stick down hard, that the "setting" value started to drop from 34%. Eventually with a lot of playing around, I got it to go to 0% and the throttle warning turned off. Now I can control my models and get to all the menus.

SOLUTION: patience at holding down the throttle for a long time.

new problem of the trim switch for rudder only working in one direction. Took apart case and all screws on controller board for switches. THen the rudder trim worked again. So that is solved. Now the throttle level will not change from full. I think I have bumped some of the controller wires and need to re-solder.

So if I get it all working again, will I trust it to fly an airplane or a drone in the air? What if it locks up when I am flying? I see that Banggood.com has the same unit for $75 called FrSky. Is it worth replacing or should I move up to something else that will give me better operational features and reliability? Looking for comments.

Move up to better system. Fr Sky has nice budget Tx now.

Spektrum has a couple lower priced units.

Graupner has really new 12 channel Tx.

Many good choices better than Orange.

UPDATE: did re-solder of leads. That was not solution, the pc on the bot is flaky. If you push on it and glue it down, then it works for awhile, then stop again. So unit is toast and I move on. I have the EVO from Multiplex so I know a good unit when I see one, but things are changing too quickly these days. Want a 9 channel for air and drone. FrSky has 7 channel for good price. Looking at others.

ORX T-Six (OrangeRX Transmitter)

Seven channel FrSky??? The QX7 is 16 or more.

To allow for RC loss condition, bind Orx T6 transmitter to receiver while in "throttle cut" mode to set that as the receivers fail-safe. I'm using Arducopter on a multirotor so this would initiate Return To Launch if there's RC loss.

Orx T6 wont output any signal at all or bind while there's any warning or error, cant bind with throttle cut switch operated. Also I don't want to bind with flight mode switch in RTL mode as I'll probably end up altering flight modes and switch positions and forget about fail-safe; In that case RC loss would initiate some other flight mode and actions or crash.

Set throttle travel to 125% down, this takes the PWM output into the throttle fail-safe region, about 975PWM on my T6. This is similar to having the throttle cut switch operated. I also set the Arducopter throttle fail-safe level to 990PWM just to be sure.
Now bind to receiver with the throttle on minimum and switches in normal positions.
Set throttle travel back to default 100% down.
Test by turning the transmitter off and observe flight controller behaviour via groundstation - QGC, APM Planner or Mission Planner - you should get a throttle fail-safe and initiate Return To Launch.

fix you won't believe for ORX-T6

UPDATE: the failure of my ORX-T6 has finally been fixed.....and you won't believe it. The failure of the Tx pot was not changed in the long term by re-soldering the Tx pot leads. The system would start and fail randomly. Eventually I realized that if I put LATERAL pressure on the Tx pot it would work well.

So I drilled an 1/8" whole in the left side of the orange case. I put in a cotton Q-tip to push laterally on the pot. That made the Tx work in all conditions. So my permanent solution is to put a bead of RTV in the case to put the same pressure on the pot. I have tested at the field and it performs as good as new. No worry of failure in the air because the throttle cut switch can be used to power down the throttle any time I needed. With a very light SLICK twisted foamy it can crash with no throttle and cause no damage to the airplane or a person on the flight line.

Go see this new ORX-T6 substitute by Banggood called the JUMPER:

Texas Instruments CC2500: FrSky, Futaba SFHSS

it looks like it can fly all the modules I have ever used. Will arrive in a few days and I will test it out.

Next I added a 5 volt Blue LED just in front of the antenna. I used Eneloop 2500mah NiMh batteries and wanted to be able to charge them without opening the battery compartment so I added a 2.1mm charge jack. Total cost of TX, shipping, batteries and mods is right around $95.00.
Bill, I am intrigued by your charging jack idea.
I just ordered the newer Orange T6i transmitter to back up my old Spektrum Dx6i.
I like everything about the ORX transmitter EXCEPT the lack of a charging jack.
I'm in the habit of plugging in my Dx6i as soon as I return home from a sailing or flying session with the Spektrum trickle charger.
Very convenient, never have to take out the LSD Nimh batteries.

I would appreciate it very much if you could proved me with a detailed wiring diagram and instructions for adding this jack.
I am handy with a soldering iron and have built Heathkit radios, so I am not an entire noob, but I don't want to do anything to damage my brand new radio either.
When you said you were able to use the Spektrum charger did you mean the one with the center pin opposite the to normal charger jack as mine is?
