Dennis Savarese" Subject: Re: Yak-List: Best Fuel Economy Settings It was an FS450. The manual for the FS450 is the part that's complicated. Most folks agree the manual was poorly written. Once you get it set though, I find it quite simple to use. Maybe that's because I have a Yak 52 and always fill up at the fuel pump. Simply press the AUTO button after the initial test cycle and the fuel quantity is reset to full fuel.

I recently sold a aircraft in which I had installed a FS 450. too complicated to use. Shadin is much easier. Now have a 18T on the water to Australia and hence interested in the instrument that you used. Cheers and regards, Chrs. ----- Original Message ----- From: A. Dennis Savarese To: yak-list@matronics.com Sent: Wednesday, June 18, 2008 9:42 AM Subject: Re: Yak-List: Best Fuel Economy Settings Peter, You should first have your manifold pressure instrument calibrated by an avionics shop. It's very easy to adjust by removing the screw at the back of the instrument. Regardless of what I or anyone else says is the so called "best" power setting to achieve the best MPG, it will depend on barometric pressure, altitude and wind speed and how well your carburetor is "tuned". In other words, it will vary greatly depending on conditions. The fuel flow instrument when coupled to the GPS, including a handheld, will display the MPG which you can then play with the prop and manifold pressure. Simply saying, "set the prop at X and set the manifold pressure at Y" is not going to work very well because of the variables previously mentioned. From my perspective, it's the best $500 I've spent on the airplane because it does allow me to save fuel. And at $5+ per gallon, it doesn't take long to pay for itself.

Van Staagen To: yak-list@matronics.com Sent: Tuesday, June 17, 2008 3:10 PM Subject: Yak-List: Best Fuel Economy Settings A few people on this list have been talking about installing Fuel Flow measuring equipment in their planes. I=92ve also noted that these systems can be integrated with a GPS so you could get best miles over ground per gallon information. Then, the compelling question is, at what prop and manifold settings are we seeing the best mpg?

Frank Surfas ________________________________ Message 8 _____________________________________ Time: 08:58:07 AM PST US From: Cpayne Subject: Yak-List: Egt settings EGT temps vary with probe position, exhaust pipe leakage, etc. It is the Relative number that means something. Unless the engine is equipped with a 9 point EGT, I favor leaning to the Rich side of of peak because there may be a few cylinders leaner than the indicated temp. Another factor is that a supercharged radial has good fuel distribution: there is a lack of "roughness" like flat engines when lean of peak ... everything can get quiet real fast.
