OK, I'm going to Joe Grice's place tomorrow to get his take on the tank plumbing situation. HOWEVER, my son, who is working on his full scale instrument rating right now, brought up a good point. With "series" plumbing, the clunk of the tank closest to the VAT would still have a full tank to swim around when the flight is 1/2 over, making aerobatics safer. 3/4 of the way thru the flight, there's still going to be 1/2 tank for the clunk. This seems safer to avoid a flameout than series, where each tank would only be 1/4 full, increasing the danger of sucking bubbles near the end of the flight. Comments?
