Like a lot of things, this is one that I have been meaning to make for several years, I have the pump but have been putting it off mainly due to over complicating the coupler, but you seem to have overcome that issue, I like it. What info would you be willing to share on you build?

You can PM, email or call me.  Happy to help.  Might be easiest to talk.

Kevin Westbrook can be reached at 918-521-5139.   Cecilia Henderson is at 918-836-7701.  Kevin helped me last month over the phone.  

Thanks, coincidentally I communicated with Cecilia via email as recently as last week.  They are as responsive as ever.  This was one of the most under-appreciated companies in the business.  When set up right, the systems are really impressive.

So Raymond is that the mechanical circuit equivalent to electronic comparator circuit for heading ?

The "electrical circuit" takes its heading reference from the heading sensor BI 102. The role of the BI 603 controller is to amplify the signal received from the BI 102 and then modulate the voltages of the left/right outputs accordingly. This signal is sent to the servo motor of the turn coordinator which drives the pneumatic valve acting on the servos of the traditional PC system.

One could replace the BI 102 by another flow valve or another cap reference, such as a directional with slider "HDG" for example. If I chose to keep this BI 102, it is because Brittain modulates the signal to obtain 2 turn rates (rate 1 and rate 1/2), that this modulation is carried out via the voltages sent to the BI 102 by the controller BI 603 (there are 3 dedicated twisted pairs in the beam BI 502, one of which concerns the turn rate 1/2).

Maybe consider posting Kevin’s number in a way that cryptic to prevent bots from adding it to a list. Like so:

nine 1 eight - fife two 1 - 5 1 tree 9

Pirep from Cecelia: Kevin has a new phone number Five 3 Niner, two niner two, zero quattro seven quattro. She is back working FT at Brittain helping the new owner to get a repair shop for Brittain components opened.
