JR have two failsafe settings
1. Throttle position set while doing bind process and all other flight surfaces will hold last position before loss of signal ( default )
2. Pre set position on all surfaces set while doing bind.
The second bind process requires you to remove bind plug after establishing blinking receivers after powering up the receiver, then power up the Transmitter.

If you don't do this the failsafe will go to default

Refer to manufactures manual of course, for detailed bind process

The main reasons I use my setting is first it instantly tells me something is wrong (even before the sound of the motor gets to me) and prevents the plane from leaving the area. If the plane is set with neutral elevator it could fly into a crowd so fast nobody would have a chance to react.

If your'e flying 10 ft over the runway inverted and go into failsafe, no setting is gonna save you but if you fly like that then you probably won't be upset losing a plane every now and then

Isn't the manual there just for the female flyers? lol

Yes, and ppl that want to know how their large scale planes can be made (somewhat) safe at least...

Hey there is no manual to tell you how not to dumb thumb and about 95% of crashes are due to dumbthumb or setup or using hobbyking recievers

By setup you mean when people don't read the manual but go ahead and configure something incorrectly?

na i mean when people don't know what they doing and set things up wrong even with the manual ie satelitr rx's too close to main 1 or rx too close to reg they don't tell you about that in any manual

Doesn't seem to work. I'm pretty sure I followed your steps exactly. And I tried other things too. When I turn on the RX only, the surfaces go to their failsafe positions, but if I have the RX and TX on and they're connected, I'll turn off the TX but the RX just stays in the last position. It does not go to failsafe position. I know the RX has the fail safe stored from binding since it kicks in when I turn the RX on by itself...

Well there is your first problem. Don't trust someone on the interweb when there are perfectly good instructions available from the manufacturer. :-) (No offence BeverlyFlyer but your instructions are wrong)

Ok, I just did this a few the same as the DSX-9/9303.

Step 1. Get the JR instructions (here) for the 921 receiver and follow the instructions in the section entitled "R921 Binding Instructions".


Here's the cliff notes summary:

Before you begin, make sure your throttle trim is set such that the engine is running smoothly at desired failsafe RPM when the throttle stick is all the way down.

1. Put the bind plug into the RX bind port.
2. Leave the Tx off. Turn on the Rx. Rx and satellites will flash.
3. If you want "SmartSafe" then leave the bind plug in during the whole process. Move the TX to the desired stick / switch positions (low throttle and neutral controls. Ignition still ON). If you want "Preset failsafe", now is the time to remove the bind plug.
4. Press and hold the bind button and switch the Tx on. Leave the bind button pushed in until all Rx and Satellite LEDs are solid and no longer flashing.

SmartSafe means throttle goes to idle, but everything else holds last position.
Preset failsafe means you establish the settings you want for each channel.

Don't forget to confirm that the throttle and ignition cutoff are doing what you want when the Rx loses a signal.

I urge you to read the manual. It provides more info than I've given here.

Thanks. I read the TX manual but what it said, didn't work. I'll try what you said.

It's receiver specific. Hence the link to the Rx manual. If you have a different receiver then the procedure might be different. Good luck.

It worked! Thanks. I've been trying to figure that out for a couple years now. I put my fail safe in a down flapperon, up elevator position.

How's what can be achieved with some knowledge and a manual !!!!!!


Well done

Thanks. Just for the record though, I've tried following the TX manual for a long time and I didn't think any RX manual would be different. Yes I read manuals and I've saved myself some $ in the process
