In that case the "head" is the same for both tanks regardless of where the header tank is positioned laterally (left or right of the center-line). That also determines static fuel pressure. Given the same resistance to flow from both wings to the header tank, the means that, for the same head, you will have the same flow. But even a small change in the coordination of the aircraft will then have an effect on the flow from the tanks because the head for each fuel tank will be different. This is why it is so important to make sure that you level your airplane and then precisely adjust the balls to be in the center. FWIW, 100% of the airplanes I have checked have had their balls not centered when the aircraft was leveled. (In most, the instruments didn't even agree with each other, let alone indicate level.) And it is so easy to do that I don't understand why people don't do it. When the aircraft is on jacks for a gear-swing, lay a bubble level across the canopy rails. Adjust the jacks until the aircraft is level according to the bubble level. climb into the cockpits, loosen the screws on the AI and needle/ball, and rotate them until the balls are in the center. Retighten the screws. Done. Now you can believe your balls when they tell you that you are not coordinated. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 brian@lloyd.com +1.767.617.1365 (Dominica) +1.916.877.5067 (USA) ________________________________ Message 3 _____________________________________ Time: 03:37:28 PM PST US From: "Chris Wise" Subject: Yak-List: M14-P Prop blades I notice that Yakdrive is looking for a set of prop blades for his 18T (?) Alex from GT Propellers has a set of 2.5 Diam GT Blades for sale in the US. I fitted a set of GT blades to my Yak 18T and the increase in performance was immediately obvious. Shorter take off distance, better climb and hence a better cruise speed at the same power settings as with the original V-350 prop. Alex can be contacted at info@gt-propellers.com Cheers, Chris.
