Cleared for Takeoff
I'm considering installing a vacuum operated turn coordinator and have been advised that at the lower speed range of my Fly Baby, say climbing at 55mph, the 2 inches of vacuum needed to run 1 gyro instrument may not be provided by a "2 inch" venturi. I have a 4 inch venturi but it's really huge. I'd rather have the cute LITTLE 2 inch venturi hanging on my plane but I can't find the specs anywhere to verify the minimum design speed of these venturi's
Anyone happen to know the minimum speed for a 2 inch venturi to produce 2 inches of vacuum?
Thanks,
Matt
