i was wanting to put ail-thro, ele-thro, and rudd-thro in my 10x for my trex, is 15% a good place to start on all eccept the rudd-thro, and put it at -2% and -2% ?

I think that all might depend on the blades you're using, how much pitch you running, maybe even your mixture, i dont know.

I use -20%/20% on cyclic, -8%/-8% on rudder and that seems to work pretty good for me.

go ahead and try 15%, add more or less if it needs it.
right?

good deal, at least i can build on that then. i have +12 -12 and vblades 600's, 95mm vblade tail. is -2 good to start out on rudd? i haven't added any atv to rudd, still 100% seems to be quick enough.

you dont need any thr mixes on rudder this is why we have heading hold gyro's

When I used the mix , I only used it one way on the tail rotor . In one direction you are increasing the tail pitch so more throttle is required , in the other direction you are actually reducing the tail pitch/load . You could argue that you should reduce the throttle with less tail pitch , but I left it alone .
I used 20% mix with cyclic and 10% with tail rotor .

At the end of the day , it gets dark .

inkspots is right. HH gyro if set up correctly you wont see any change, its job is to compensate for that. If you did add some, it might only cause the gyro to have less work to do, (and as you can see -2 +2 isnt much "work" anyway.)

So what gyro do you have?

Also wondering do you have a govenor? I "think" with a gov (and I am sure I will be corrected if I mis speak) adding throttle mix to aileron or elevator is a useless taks as well, since the gov handles this quite well. Again you wouldnt notice any difference with a giv turned on. (if you had it disabled say in normal mode than you could set up these mixes for normal mode only.)

inkspot1967, you say dont use rudder-thro. mix, why not? it makes you stay level left or right hovering piro, would it conflict with something else?

never used it or is it ever needed with todays gyro's simply put. even adding ail-thr mix is not needed if running a gov like simmer said. the gov over rides this function anyway. but with no gov its good to use it

i've got a 401/9254 and a throttle jokey pro. and you make sence. ok i see the point, i was wondering about using a gov. i couldnt figure if the throttle would move after you turn the gov on, huh?

the tjp will over ride the thr mixes if you turn off the gov the mixes will work again.

the whole thing about rud-thr mix was really for old school gyro's like rev-mixing gyro's

You're missing the point . If you pirouette while hovering , and don't change the throttle/collective , in one direction the heli will desend in the other it will climb . This is because the headspeed is changing with the changing load of the tail rotor , and we don't want it to , hence the tail/thottle mix. So if the headspeed changes , so does the tail rotor speed .
The gyro can deal with it , but if the tail speed is constant it doesn't have to deal with it .

At the end of the day , it gets dark .

OK I didnt think of that and it sounds correct but... if you pirio with the rotation of the main rotor, (clockwise) wont the GOV see this as a drop in RPMs, lower head speed and correct it? so in the end, it should not matter?
