Hey Clive, When you mentioned the original Lightning, did you forget the P-38? And of course now we have the latest Lightning, the F-35, Lightning II. All are great airplanes, both past and present. Alas, I wish I had been able to fly all of them, not just the Arion model. Blue Skies, Buz **************Looking for a car that's sporty, fun and fits in your budget? Read reviews on AOL Autos.

If so what RPM is turning in good figures with a reasonable cruise? Hi Clive, During my initial 40 hour FAA Phase One testing I did some "Range verses MPH" charts for N31BZ that would basically be the "optimum MPG" info that you are looking for. Actually, everyone should plot this data for their aircraft, but I know how busy we all can get. Heck, I have changed props several times since I ran those test, so my data is "old" for my airplane as it is configured today. At the time I ran these test I was using a fixed pitch Sensenich - W64ZK54, and I only plotted data for 5,000 feet and 10,000 feet. I "assumed" a usable fuel of 25 gallons which would have given a fuel reserve of 3.8 gallons for 31BZ. (Of course, the OAT air temperature when you are refueling will vary the amount of fuel you can actually get in the tanks.) After I plotted the raw data for the various speeds I then had the computer "smooth" out the data curve (polynomial?) which resulted in a smooth data curve. Having said all that, with the prop I was running at that time it looks like 120 mph (TAS) would give the best MPG for 31BZ. In other words, 31BZ would have a range of about 1000 miles at 10,000' when flying at 120 mph (TAS). MPG for 31BZ at those numbers is close to 40 MPG, but who the heck wants to go that slow.

    Subject: Any difference in cooling requirements between the
    hydraulic and pre-hydraulic engines?
    From: "James, Clive R" <clive.james@uk.bp.com>
    Thanks for the oil cooling pictures. I can see it needs a fair amount of cooler. I've sent through some info on my CHT cooling direct. Thanks everyone for the other cooling tips and info, it will be another two weeks before I get to fit and pipe up my new cooler but I've got lots of ideas about what to do next.

To: lightning-list@matronics.com Date: Monday, August 11, 2008, 2:56 PM <clive.james@uk.bp.com> I have a hydraulic tappet 3300 Jabiru engine. I've been chasing an overheating problem whilst having a cooler that was recommended to do the job. I've proven to myself that the cooler is too small and I now have the cooler that is standard fit for the J400,430 etc. I've not yet got it piped up and tried it but on the basis that this cooler in the UK is usually partially blanked off I'm assuming my overheating problem will go away. One thing I did wonder about, has anyone come across a difference in cooling requirements between the hydraulic and pre-hydraulic engines? Thanks, Regards, Clive

    Subject: Esqual-Lightning real cruise for best MPG
    From: "James, Clive R" <clive.james@uk.bp.com>
    Slow is good at times, I imagine even 145 knots is a little slow for an Ex Jet Jockey! Thanks folks for feedback on mpg. 120 mph must be a nice steady cruise and 40 mpg sound good! Hopefully I'll get some numbers in a few weeks then I can set to improving them with some drag reduction.

    Clive=2C You're probably right. I think the landing speed on an F-4 is about 145 knots or so.
