Throttle/elevator mix

       Remove this ad - become a site supporter!
I have a Futaba 9cap and I am mixing throttle to elevator (slight down elevator at low throttle). here is my dilemma.
I have split elevators and am using ailovator mixing with the aileron function for the elevators mixed to zero so my elevators don't do the aileron thing. The servos are on channel 2 and 8.

For the throttle to elevator mix I am using mix 1 and for the other side I am using mix 4. For some reason I can't seem to link these so that when I adjust , I have to do each side independantly! When I used mix 2 and 3 for rudder coupling in knife edge, I am able to link these and adjust from one mix for the (independant ) aileron servos.

Any ideas?

Hi There

Just a passing thought and I may be out in left field!

I don't use Futaba equipment. But looking at it makes me ask if the mixes might have to be sequential in order to couple them.

Like 1&2 and 3&4???

1&4 don't work together for you but 2&3 do.

You should be able to do this using the "link" button. This allows two servos to be operated as slave channels, at the same time. Mixing it to the Elevator, should then automatically bring the other elevator servo along for the ride.

mixing it up

I think I got the answer on Flying Cirkus ( )

I will turn ailovator off, mix channel 2 and aux2 with mix number 1, then mix throttle to elevator with mix number 2 and use link on. Then I will use the hitec programmer kent just got to reverse one servo, set end points and atv so they track together without the lag I presently see. Apparently the lag seen is because of the frame rate differential as the signal goes through the receiver from channel 2 to 8 in a sequential manner. There is also a lag if one of the servos is reversed, hence doing it internally via the hitec programmer instead!

Should do the trick....let everyone know.


PS Ain't IMAC grand?
