Every time I go to program the elevators with the 10x the elevators do not work together. One is always slower. When I move the stick around fast it looks like they are ailerons.

Any ideas?!

I assume you are using the dual elevator function in the 10X.
The only time I've ever seen any problems with my 10X on elevators, I had too much subtrim input on one or both servos. This will cause the problem you are describing.

I do have a little bit of subtrim on both servos. I'll get rid of it and see what happens.

Thanks!

Just got the problem sorted out. I had one elevator servo in the wrong channel.

Thanks to Jeff Szueber and Eric Powell for the help!

Check your mechanical setup. I've seen problems there too.

Print out a little paper protractor and make sure bother servos have exactly the same center point and they both sweep exactly the same number of degrees... preferably around 50-55 degrees. Once you do that, adjust the length of your control horns and pushrods to get equal throw. Should fix about anything. Mine track perfectly on my 10X.

I have never used that function. I use the AUX 1,2,3,etc.. programs

The higher the aux channel number -the worse the time error - I had all the PCM10 models over the years -same issue- best ALWAYS --is no sub trims and use the built in mix on the screen . It will never be as good as the 9303 or the DX7-which is the best of all of em. (least error).

I have no doubt that your correct Dick.I will put that in memory, but Hitec servos, and good geometry make it possible for all subtrims to remain at 0 forever. As far as I can tell, I can't see any real latency between the two control surfaces, but one day, I should try the elevator function, the only thing is I haven't had the need to, and if it ain't broke......
