Terry Schubert was kind enough to come down and spend the day looking at our engine plenum, baffling, and NACA ducts to see if he could help us understand our cooling performance better. I’ve had a digital manometer for some time, but I didn’t think it was working. I’m a pump guy at work, and I have to admit non-compressible fluids are not my forte’, and I had some preconceived notions about how much differential 1″ of water really looked like.

At any event, he was good enough to get some aquarium hose and air stones and fly down to help me figure out where we should hook them up. Then he gave me his favorite test sheet and flight test parameters, and Beth and I went out and flew the test. We really should’ve done it earlier in the morning when it would’ve been easier to hold tight altitudes and speeds, but at least we got some baseline data that we can compare to in the future to see if our changes are helping or hurting.
