Help!!!!!!!!!!!

I am setting up a plane for a friend. I am a JR user. He has the 6XA.

The problem:
He has dual elevator servos. I have been able to get the mix working. I am having a problem getting rid of the other channel. I don't want him to flip a switch and crash the plane. He's been out of the hobby for a while and just getting back in. He gave up trying to program and wants me to try. I need to know how to disable the switch or inputs of either channel 5 or 6. On the JR radios you can go into the ATV of the slave channel and zero it out. It will disable the slave channel input while letting the master mix continue. I tried to do the same thing with the Futaba and the ATV affects both the slave channel and the mix from the master channel.

I've been through the manual twice and can't seem to find the answer.

Thanks

Mixing a channel to itself 0% will have 0 effect. You need to mix ch 5 to ch 5 -100% as described in our FAQ at www.futabarc.com

Please note that your friend's elevator trim will only trim the elevator servo! and will not trim the second servo. The 6X is a very entry level computer radio and is not designed for this type of setup.

AQ,
The 662 has the exact same issue - the mixes do not support trims. Only higher end radios do this.

The flaperon function is a fully built in function, with proper performance on all levels including trims. The elevon and v-tail functions are also complete functions. You're asking to create a mix that simulates a full blown function, and entry level computer radios simply don't support this.

Doing a dual elevator setup is an example of where you might want to use a mix, and it DOES work, but it requires actual proper geometric setup and not using the trims, which so many modelers are now so dependent upon the trims that we once didn't have at all that we don't recommend it for fear someone will make this error.

The 6X manual clearly covers how to create a mix, but its up to the user to know what s/he is trying to do with it.

You're right. SAme problem with 662. I'm going to do a Y-harness with a reverser. This is the first time I have had to do dual servos with a reverser. The plane is not for me and I'm sure the person would have a hard time with the trim if it needs to be changed.

The manual does talk about making the mix, easy to do. It doesn't state how to get rid of the other channels input and that was the frustrating part. I also wish the manual clearly stated how to change modulation. If you do it per the instructions you can't.

Aq,
I do understand your example of hte manual not telling you specifically how to do that example. please see the 9C manual addendum pages to see how the newer style US only manuals work, with specific examples covered step by step.

...AND, you've pointed out a flaw in the manual i've never caught before...
under PARA on page 40 it says... "there are 5 submenus....To access these menus, you press the CURSOR key to step through the sequence.

HOWEVER, the instruction for this partiuclar feature skips the fact that you land on PARA and then cursor over to MOD. THANKS! I will get an addendum done for this problem immediately and have Japan notified for future manuals prints!!!

To do so properly, go to para menu, cursor over to MOD, if it is P that means PPM (FM), press the + key to go to C, then turn TX off and on again and you're in PCM. Vice versa to go to PPM from PCM.
