KR>Vacuum Source

[fixerjo...@aol.com]

hey scott,,the prop blast does provide almost ample vac volumn for the DG,but 
a far cry from supplying enough vac for the artifical horizon.  the venturi 
supplies too much vac (9 inches) at speed. you must use a vac regulator to get 
4.5-5.5 inches. too much vac will burn out gyro berings quickly!   if anyone 
figures out how to elimniate that ugly,draging thing,,let me know. untill 
then,it gets the job done.
