problem with 9zap (two elevator servos setup)
confused: Dear frinds I need help with 9zap
I am using two elevator servo, with my zap in a edge 540 with a R 149 dp the instalation is as follows :the one servo is plugged into channel 2 and the second servo to channel 7 ,I am using programmable mix 1 to slave channel 7 to channel 2 and trim field on. So far so good , but I have different speed in each servo when I am adding full stick .
By the way the expo is setting the same (0) for both elevator and av2 . and also
the servos are identical (robbe digital st 250 )
Does any of you knows how I will fix this problem .????

From what I can remember, on my Aeroworks Freedom I used the Ailevator function. Check that out and let me know. It worked fine for me_bob

Like Bob_NJ mentioned, just wondering why you aren't using the built in ailevator mix?
I'm pulling this from brain memory which isn't always real accurate so you may want to double check this. The built in mix is in the conditions menu area and I think it is called ALV. It will use channel 2 and 5. Enable the mix and set the ail->elv mixing portion to 0% if you don't want ail->elv mixing. You can reverse one servo by changing + to - (or visa versa) in the mix or in the model menu area. Also be sure to set the default knob/switch for ch5 to null.
Another thing to check is the actual servos and linkages. While they may have identical model #'s, one could have a different transit speed... I've seen it happen before. If a large diff exists, this can be an indication that the servo is going bad. Also check linkages. Be sure they are set up the same, especially check the orientation of the servo arm to the hinge line. Different linkage setups can cause surfaces to move at different speed. Also check for binding. Added friction from binding hinges, etc can cause on surface to move slower.
Cheers.

A couple of things typically cause this problem.
FIRST and FOREMOST start with a fresh model memory, or RESET the one your using.
USE the Ailevator MIX together with channel 2 & 5, TRIM link ON. Zero out the aileron function percentages.
SET the the SUB-TRIMS, SET the ATV for all channels. Only set th ATV ONE time, never come back and change the ATV after you have initially programmed your TX, or you'll have to go in and change other settings. Use AFR to adjust travel volume for normal or HIGH rate and use the Dual Rate function to set the LOW rate's.
If you have an early 9Z, the software suffered from a slower frame rate. A slightly but notable mixed/slave servo was not uncommon. Later TX models addressed this issue.

my zap9 is one of the first models and i think that this problem of the software is not the only one if you have to use several mixed/servos .I have suffer a lot of times trying to setup radio gear to models that required more that 3 servo for flaperons and speed breaks .
