[NSRCA-discussion] SD-10

Tue Aug 25 13:38:48 AKDT 2009

Here's a link to the independent tests run by someone over on  RunRyder 
Heli site.  Doesn't look like any tests on the new Airtronics  gear yet.  Right 
now the Futaba 10C with the HS receiver is fastest  average, fastest 
minimum and least spread min to max (consistency).  I  think Dave L mentioned in 
this thread that consistency in response was probably  as important as 
anything else.  The third chart graphs that out for each  system.

Pretty interesting tests tho I have to admit I am finding it harder to  
distinquish between 9AM and 10AM so an improvement of 7ms probably isn't going  
to be too noticeable by me..

RE: Stick centering. The Hitec servo programmers can read the pulse  width 
down to 1us I believe. Plug it into a receiver output and put it  in the 
right mode and it will display the pulse width.

RE: Latency comparisons, pullled this from the web:

These latency findings were taken  using carefully contructed and 
consistent methods to ensure they are  as accurate as possible. As of May 2009 

Airtronics SD-10G:  
Min: 7.36ms 
Max: 16.3ms 
Ave: 11.83ms

Futaba 10C  (Futaba is a Trademark of Futaba Corporation and Dist by Great  
Planes): 
Min: 9ms 
Max: 29ms 
Ave: 19ms

JR 9303 &  R1221rx (JR is a Trademark of JR Radios Japan and Dist by 
Horizon  Hobby) 
Min: 25ms 
Max: 47ms 
Ave: 36ms 

JR 12X  
Min: 21.5ms 
Max: 43.5ms 
Ave: 32.5ms 

Of course, this was in an ad for  Airtronics. ;-)
