Yes, please, send the graph = of in. of water vs. airspeed.  Is there a graph of in. of water to = altitude?  I have a how-to from EAA that goes through all of the = calculations here:

The pitot system you can check yourself. Rig a water = manometer of clear vinyl tubing with a scale behind it.  Connect = one side (leg) to your pitot tube; move the other leg up and down to = vary the difference in the height of the water column.

I'm ready for a pitot/static and transponder = check and I'm wondering a couple of things:

 

1.  I'm in Santa Barbara, CA and my = local avionics shop is not only horribly expensive, but also has little = or no experience with experimentals.  Can anyone recommend an = avionics shop in the Southern California area that knows how to work = with us?  Anyone out there mobile?

 

2.  Any advice on how to do this with = the least amount of pain?

3.  Is the certification required for = the DAR?  Can I get my final inspection done before the = pitot/static thing and then fly somewhere else for the = certification? 

Thanks to everyone for all the help and many = many posts on all subjects rotary.  I want to be in the air in = February.

Best Regards,
