<DIV>I find that 0.13 dead band works well. Gear wear isn’t usually a problem
with the 173, the Futaba aluminum arms don’t fit the splines tightly though –
you might check this if using these arms. Lots of folks use the 173 on bipe
ailerons (which tend to be smaller). Some time ago I measured servo current draw
on each surface and ailerons were by far the highest – as Peter notes, big
surface. At 7.5v they might be OK, I use the BLS171 which has 60 or so more
oz-in torque. I’ve also found that servos slow a fair bit whenever current draw
exceeds 60% of stall current – another reason to err on the high side.</DIV>

<DIV dir=ltr>Guys,
<DIV>I'm new to Futaba programable servos. Have new BLS173SV on ailerons
and have a bit of "slop" in the servo output. I'm confident that the
majority of the slop is in the servo, not the linkage. </DIV>
<DIV> </DIV>
<DIV>Should I need to replace gears after only a couple hundred flights?
Hard to tell, but seems like there is too much slop with power off, so adjusting
settings may not be the answer. Can't find the gearset on Futaba or Tower
website anyway. Anybody know the part number and how/where to order?</DIV>
<DIV> </DIV>
<DIV>I was going to try reducing the deadband from .36 to .20.</DIV>
<DIV>Recommendations on programable parameter settings improve centering?</DIV>
<DIV> </DIV>
<DIV>Thanks, Dan</DIV></DIV>
