AR7000 sets throttle at wide open when turned on
This one has me baffled. I have an AR7000. If the plane is turned on without the transmitter being on the throttle goes to wide open.
The failsafe is set to idle and works fine when the transmitter is turned on before the plane and is then turned off. Why would it go to full throttle without the transmitter being on?
The transmitter is a JR X9503 DSMX

Problems can arise if you turn on the Rx before the Tx, except during the Binding process. I have had instances where I had to ReBind becasuse I turned on the Rx before the Tx. I try not to ever do it.
Failsafe kicks in when the Rx loses the signal from the Tx. When you turn on the Rx, without the Tx on, I do not believe it goes into Failsafe. Something else is happening to trigger the Throttle response you are seeing.

Bind it again and be sure the throttle stick is all the way down.....did you reverse the throttle servo after the first bind?
When in doubt, bind!

Why would you NOT turn on the transmitter first ?

RE: AR7000 sets throttle at wide open when turned on
Depends on which failsafe mode you're testing. His testing method is correct for testing the startup positions of the channels.
If you want to test the other failsafes, you need to do it as you described, by powering down the tx after linking.

I have inadvertantly switched on rx and telemetry while switched to wrong model, and lost the binding, is this normal.

Are you saying that turning on the Rx, before the Tx, is Ok? What Failsafe Mode are you testing for? I was told that turning on the Rx, before the Tx, could possibly cause Binding issues. I am sure this happened to me at least once and forced me to Rebind an AR9000. Am I mistaken?

The only receivers that would have "binding issues" would be the AR6400 line. They go into bind mode when they don't see their tx already on. But just powering them down again will NOT erase their bind. You are mistaken that about it causing a bind problem with and AR9000. It might take longer to connect, though, since it's scanning all frequencies looking for the tx.

You didn't lose bind. The only way a receiver and/or TM1000 loses its bind information is for it to be re-bound to something else. You may have to power cycle (as noted above) to get it to quickly re-connect to the transmitter, though. The rx did not lose bind.
A transmitter, otoh, erases its bind information as soon as you put it into bind mode. If you put the tx into bind mode, then you will definitely need to re-bind the rx for that model number again.

RE: AR7000 sets throttle at wide open when turned on
I've done that by accident with my DX7.. the bind button on the back was up against the divider in my "pit box" at a race, when I reached and turned the TX on, apparently I pushed hard enough to depress the bind button..
After that, I made it a point to take the radio out of the box, hold it in my hands to turn it on, then set it down. I may be an old dog, but even I can learn new tricks once in a while..

RE: AR7000 sets throttle at wide open when turned on
My concern is that one servo is being commanded to full travel in one direction. None except the throttle exhibit this behavior. If by accident the plane was on but not the transmitter (I know we have all done this at least once) I would have wide open throttle. None of my other Spectrum receivers do this. It's puzzling.

I seem to remember reading some threads with warnings about never turning on the Rx before the Tx, except to Bind. My AR9000's need to have the firmware updated as I purchased them when the Spektrum Modules first came out, so they have a much longer Reboot time.
What did you mean regarding checking the Failsafe Modes for Startup Channels by turning on the Rx before the Tx?
