No you miss understood you program the tail esc so it thinks 1/2 throttle is full throttle zero is still low throttle position. That way the Gyro/esc see's about the same value as if it was pushed to one side or in the middle of the rudder channel. So you still arm it normally.
If it does not work with your particular ESC then just slave the rudder channel to the throttle set both values at +100% and start there you can make the esc arm normal. I have done it three different ways with a DX6I and they all worked. I would scrap the two in one a ESC at hobbypartz is only $10 for the main and that is a lot cheaper than a converter.
Another way is to define the throttle as the master the rudder as the slave set the slave at -50% the tail motor will be off when the throttle is down and then you may have to set some subtrim.
I have read other ways to do it but there are a number of ways to get around it there is a guy on RCgroups right now that has done it by eliminating the 2in1 and that thing flys better than any stock one I have seen. But if you want to keep the 2 in 1 just dont hook up the tail it should not affect the brushless esc in the 2in1 for the main... Ray

This is getting too complicated.
Let me fill you in on the set up I have seen work perfectly....
Add a 10 amp ESC for the BL tail motor.
Connect the main power wires parallel to the main motor ESC power wires.Now one plug powers both ESC's.
Remove the power wire from the three wire rainbow wire on the tail ESC.Plug this into the gyros output.
Connect the three power wires from the ESC to the tail motor.
Plug the gyro into the rudder port on the RX.
Done.Flys perfect.

Thats just what I did the rest is just how you want to program your radio... Ray

The way I said means....No tricking the ESC.No crazy sub trim values.
Just plug and play.

You dont need a converter you just go from the 6110 to the gyro off the gyro to the esc from the esc to the tail motor. One important thing is you have to remove the center signal wire on the esc from the gyro just pull it out of the connector and put some heat shrink around it. If you do not you will be feeding power to the gyro from two locations plus the bec's in the esc will be fighting for control one will lose.. Ray And here it is.. Ray |

The only reason that comes into play is if your tail motor does not start up when you want it or continues to run after the throttle is down. But some esc or gyros will not arm unless the rudder is to one side and then after it arms the tail motor will run all the time. The particular esc/gyro I had did not have that problem. And I mentioned the same setup you are refering to on RC groups but he has stated at the end of his post he had to mix the rudder with the throttle hold that means his setup has the problem of the tail starting up or not shutting down.

Gotcha  What's your handle on RCG? PM it to me if you prefer. |

I'm going to try that, as I don't like the idea of the BEC from the tail motor fighting with the main BEC. I'd too much prefer a set-up that works without any crazy settings. |

Is there an echo in here??? Again read on he had to slave the rudder to the throttle and put the rudder on throttle hold so the tail would not run all the time. It is yet another way to stop the tail from running on its own. Pulling the power wire from the tail esc has been stated before in a previous thread. Ray

Ray Sorry Ray, I don't see any reference to slaving the rudder in Ernie's posts, just yours. It looks like Ernie ended up recreating the same connection logic that I did in the test video of mine, our radio settings are just different and I didn't cut the BEC line from my tail ESC. Can you describe in clear steps how you think you can "slave the rudder to the throttle and put the rudder on throttle hold", because I'm pretty sure this is not going to be achievable for people using the stock radio.  -Rob. |

I should point out that my username on RCG is "thesteelcube", so I'm aware of what that guy did because he is me.

I did not have to do it on mine but I did experiment with it I used a 6amp pentium esc and a gyro like what you buy from xheli for $12 A GS 192 and it did not have the binding or startup problem it saw the center of the rudder as zero throttle. Without a programmable TX the DX7 is the best for this I dont know how you would get around it unless you used a revo mixer from Dionysus design's and then it wont work with Head hold. Mine worked OK but I wanted better so I slave the Aux channel to the throttle to run the tail esc which you could do with a Y off of the throttle. I installed a brushless motor direct drive with a long shaft I then installed a trex 250 clone tail prop and slider with servo. The tail throttles up like it is suppose to and the servo hooked to the gyro does the rest.. Ray

Ah ok. Well that's that I guess. I could swap the main ESC for one of several spare ESCs I have lying around. The upshot is that the onboard tail mixer needs replacing if people are going to use their stock radio. I'll took around.
