<div>Jim,</div> <div> </div> <div>You may be correct, the stick centering depends on the quality of the stick. But, throw in 256 instead of 1024 resolution, the step size is now 4 times as much and it would be much more noticeable.</div> <div> </div> <div>Ok, if we were flying the 4 channel Conquest transmitter (cheap plastic gimbals) with 148 servos (non-ball bearing) in a slow moving trainer, we probably could not tell the difference between 256 and 2048 resolution. So, would I be better to fly a Conquest radio in pattern? That seems to be the type logic I would get from people that say 256 is "better than most servos". </div> <div> </div> <div>Oops, I forgot the Conquest is an analog radio. No steps whatsoever. ;-)</div> <div> </div> <div>Bob R.</div> <div><BR><BR><B><I>J N Hiller <jnhiller@earthlink.net></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px

The detent design and pivot bearings are less than shall we say industrial quality. Bob, I had the roll-centering problem you described with my super 7 and felt it was due to stick centering not being equal from either left or right. I think my 9-C is better but not absolute. I wish I had one of those little devices that displayed the signal count to verify my suspicion.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p></SPAN></FONT></SPAN></div> <div class=MsoNormal><SPAN class=EmailStyle15><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-bidi-font-size: 12.0pt">Jim Hiller<o:p></o:p></SPAN></FONT></SPAN></div> <div class=MsoNormal><SPAN class=EmailStyle15><FONT face=Arial color=navy size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-bidi-font-size: 12.0pt"> <o:p></o:p></SPAN></FONT></SPAN></div> <div class=MsoNormal style="MARGIN-LEFT: 0.5in"><FONT face=Tahoma color=black

I had trimming issues with my plane that I could not tune out. Some flights would be good, some I could not trim the plane for level flight (slight roll left or right). And, yes, I had taken out all the throw I could mechanically so I had 100% throws programmed into the radio. Frustrated, I decided to put my 7UAP in the plane, and it immediately felt good. That is when I decided to do a little digging and discovered the resolution

Yes, once the stick is moved away from center, 256 probably is good enough. But when the stick is at center, the darn servo better go back to the same position every time. And you need fine resolution at center so the neutral position can be varied in small enough amouts to arrive at precisely the desired position. </SPAN></FONT><FONT
