[NSRCA-discussion] Futaba and pattern

[Bob Richards]

Ron,
   
  All I can say is, I flew the Micropro with every intention of competing at the '93 NATS with it. 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 issue.
   
  Whenever I mention that 256 is not good enough, I hear all sorts of reasons why 256 should be sufficient. 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. 
   
  With a slightly worn stick or pot, the neutral position might be bouncing between two adjacent steps. With 256 resolution, this can be VERY noticeable. With 1024 or higher resolution, not nearly as noticeable, if at all.
   
  Given the outcome of the '93 season with my old 7UAP, I'm glad I switched out the radios.

  Hmmmm, I never thought of blaming my radio's resolution for my bad flying.  Let's see now..........
