I'm selling my Lightning on Barnstormers.com to buy an Archer. I am in the process of finishing my IFR rating and I'm looking for an IFR certified Archer to finish. Thanks again for your response.

John Drane Laveen, Arizona ----- Original Message ----- From: N1BZRich@aol.com To: lightning-list@matronics.com Sent: Tuesday, August 04, 2009 8:24 PM Subject: Lightning-List: OSH All, I am home from Oshkosh and just started working on the next newsletter. Hope to have it out sometime this weekend or early next week. Overall it was a very good convention. Total number of showplanes was up and there were actually slightly more homebuilts than vintage aircraft this year. Great. I think total attendance was also up - it sure seemed that way. One important thing for everyone to consider - only 355 days until the start of Oshkosh 2010.

It's goal is to both educate and motivate future builders and flyers as well as provide an avenue for current builders and flyers to exchange information. On top of that, every now and then we also try to provide some humor "just for the fun of it". Hope you can be at the Third Annual Lighting Fly-In this September 25&26.

Short story long--- what are you running for jetting and I am thinking this may be an altitude prop--not used for skud running? Nick or Buz, what jetting is needed? Thanks for any advise Dave McC ----- Original Message ----- From: N1BZRich@aol.com To: lightning-list@matronics.com Sent: Sunday, March 22, 2009 10:48 PM Subject: Lightning-List: more prop test info All, Some time ago I sent out a report on the results of the prop testing I have been doing on N31BZ with the Sensenich 62FK60. (remember BZ has the older solid lifter engine) Those emails listed the true airspeeds vs. RPMs that I was seeing. As a follow up to that message I have been doing some additional testing the last several days to come up with some fuel flow numbers with the new prop. Most of you that have been on the list for a while know that my cross country technique is to set a fuel flow (not an rpm) and accept the airspeed and rpm that the fuel flow gives me at the altitude I am using for the trip. Since I am planning another trip to SYI early this coming week, I figured I had better get at least some "ball park" fuel usage numbers before I make this next trip. On cross country flights I normally cruise at an altitude that does two things for me - I am looking for lowest headwinds and smooth flight conditions. If there is a tail wind, I go up high to take advantage of that, often cruising as high as 14,500 when west bound (yes, I have a small O2 bottle). Normally, I seem to end up in the altitude band between say 6 to 12 thousand feet, so that is where I have been doing most of the testing the last few days. Oh, one other thing, the OATs have been running slightly cooler than a standard day. For example density altitude has been about 300 below indicated altitude. Below are the results I have seen during recent flights over the last few days: -Since I normally set 6 gph I did a lot of those test. As it turns out, 6 gph seems to give me in the neighborhood of 162 to 165 mph true airspeed (weight makes a difference). I should also note that I tried to do most of the test when I had the tanks full (except for that burned during climb out) but with only me and approx 30 pounds in the baggage area (31BZ is probably around a 1200 lb airplane with that load). -However, I noticed something interesting (with the prop and set up I am now using) when I pulled the fuel flow back below 6 gph. It appears that: 5.5 gph gives 155 mph, 5.0 gph = 150, 4.5 gph = 145, 4.0 gph = 140, and 3.5 gph was right at 135 mph. I saw no reason to go slower than that. If these numbers prove fairly accurate during actual cross country flights, that works out to over a 1000 mile range flying at 135 mph tas - but who wants to go that slow. I just thought the kind of linear relationship of FF to MPH was interesting. Of course, the time spend at the various fuel flows was just long enough to let the mph settle down and things could be different when I actually make the trip to SYI (probably this Tuesday). Anyway, as normal, I will provide the data for that flight after I get there and find the time to figure it all out more accurately.

(His were true and yours were indicated). I would estimate that you would have to add approximately 10 mph to your figures to get the true speed. It will be interesting to see what the fuel jetting should be. I am sure that Nick will ask what the temperatures were. Lynn In a message dated 8/6/2009 8:26:01 P.M.

The aircraft is listed on Barnstormers and Green Landings is handling the sale for me. My reduction in work means that my income has dropped significantly and I cannot afford to keep the aircraft right now. At some time in the future I will build another.
