Balancing Left and Right Levers on 737NG Throttle
Hi Fellow Builders,
Ive been calibrating my throttle and wondered how many people have the left and right levers balanced exactly. IE When I move both levers exactly halfway.. I would want to have the Phidget Values for both levers to read the same. I find that it is near impossible in my config to get them the same. They are always about plus minus 10 phidget value units in difference. This seems to make a difference in FSX where it will start to slightly turn the aircraft in the direction of the weeker engine. Granted most flight are done with A/T on, so its not do much of a drama, but taxing is sometime annoying.
I was thinking of assigning one lever to both left and right FSUIPC engine values, and leaving the other pot as a dummy, but i guess i wanted to know how accurate throttles are in a real 737. Is there variances between left and right levers when pilots move them together?
Hope the question makes sense.

It depends upon how well the mechanic rigged them. I think most newer jets are rigged more precisely than the older series of 7X7.
I've seen real photos of 727's where none of the throttles are exactly aligned. I don't think I've seen many photos of when they were aligned unless they were at the idle stops.
I used to be anal about this and trying to synch up three is even more difficult that two.
Mine vary, not considerably, but realistically. #3 is always slightly ahead of #1 & #2 at take-off and cruise, while #2 is typically slightly ahead of #1 & #3 during manuvering at slow speed or on approach.
They all vary no more than half a knobs diameter, but it's enough to keep it interesting.Boeing Skunk Works

I had a whail of a time calibrating my throttles to sync. Not easy, just a lot of fine tuning to do. I was about a week getting mine done right.Geremy Britton

Thanks for the comments guys.
@Michael: If a little out of sync is realistic, than im happy
