John,

 

Why are you installing a turn coordinator?  It is not required equipment per AC 91-75. Put your airspeed indicator in that hole. You can probably also delete the CDI since your Chelton has a CDI function. What is the vertical power DU 107.

 

I have an over/under arrangement for my Chelton's, but to each his own. I am glad Lancair Avionics talked me into that.

 

Regards,

 

Jeff
