OOPS,    last message was not for  the list, need to wake up before I hit the send key.

  

 Also wrong pic.  Might as well correct for  everybody.   

 First batch of probes went in 3 hrs.    another 50 on the way, If interested send an email and I'll notify you  priviatly.  All that have emailed so far are on the list.

 Sorry for the confusion    John

Hi John,



 I took a look at your LRI probe picture and noticed it is significantly different from the one that I made.  I did mine according to the drawing I got online.  It seems you have rounded and angled the edges differently.



 I wonder, have you done any testing on this new probe design?  Does it work the same as the original design? Does it work better?  What happens when you put your plane in a forward slip with this new design?

This is certainly not rocket science. No sense spending a hundred years

figuring it out to the the last angstrom.



Just a mere differential pressure sensor. A REALLY simple way to test it

would be mount it on something (a Burt Rutan wind tunnel for example (a car)). with a pressure gauge (airspeed indicator, etc) on each port hop in,

stick it out the window and simply confirm a reasonable pressure 

differential across say 0-30 degrees or so. That would certainly be 

enough to tell you whether or not it will work.



Regards,

Jeff

   Correct



I wonder, have you done any    testing on this new probe design? 

    

   Yep, not new really, been around 30 yrs that I    know of.

    

    Does it work the same as the original design? 

    

   Never flew the original.

    

   Does it work better? 

    

   Of COURSE it does           Truthfully ,I have no clue.

    

    What happens when you put your plane in a forward slip with this    new design?

    

   

Indicates normally , only testing I've done    so far is on my Champ, it has been flown on several ultralights as    well.
