SJ Cowl with Standard baffles
From: 
"Robin Marks" <robin1@mrmoisture.com>
      
      Is there anyone out there flying the Sam James Cowl but using standard
      baffles in place of a plenum? If so can you please share your comments /
      results?
      
      I have committed to the James cowl on my 8A but don't want to deal with
      a Plenum (again).
      
      
      Thanks,
      
      Robin

      Chris,
      Great info.  I did something similar, but not to the extent you  did.  I'll 
      relook those issues.
      Thanks,

      When I  was installing the flap actuator, I could not get the bolts on the  
      nylon
      bushing tight without the actuator binding.  I ended up reaming  the holes 
      in
      the nylon blocks out to 5/16 and making some bushings.  I  also capped the 
      top
      of the blocks with a piece of .06 aluminum.  This  allowed me to torque the 
      bolts
      properly with no binding of the  actuator.  I have no idea if this will help
      the longevity of the flap  motor, but it can't hurt.  The motor was 
      noticeably
      quieter with no  binding as would be expected.  The other thing I did was 
      add
      two zener  diodes back to back at the motor connector hoping to alleviate  
      voltage
      spikes and arcing of the motor brushes.  Again, no data yet as  to whether 
      or
      not this increases motor longevity but again it can't  hurt.
