    Subject: Wing Tie Downs
    Hello everyone I am attaching a photo of the wing tie downs I came up with if you are interested. I reviewed the tie downs that Peter Disher installed, but I couldn't figure out how he was able to drill and bolt his bracket to the wing rib. He must be a genius! Anyway, I noticed that the Aileron Bell Crank bracket already had an extra hole in it and was just below the wing skin, so I drilled a hole in the wing skin and bolted a stainless steel eye bolt in the existing hole. Afterwards, I fiberglassed a fairing around it. Fly safe and have a great day. Gary Pennington

    Pete, It is not advised to do much taxi testing or ground run ups with your new Jabiru engine. I have installed more than 20 jabiru engines and have found that within the first few hours the engine is very vulnerable. At Green Landings in the first days of taxi testing we can only get about 2 to 3 runs down the runway without getting the temperature to hot. If i see the temps rising quickly i will shut down the engine and allow it to cool for an hour or so. Remember heat will build even after the engine is shut off. Also never run the engine on an open cowled system. This will also have the cylinder hot in mins. The best thing to do is find out if your aircraft is stable at just above take off speed and head to the sky. After the climb the engine will cool in level flight. Once you have about 10-15 hours and change your oil at around 25 you will see very noticeable temp differences. After the break in period you will be able to run your Jabiru engine on the ground without any problems. Another thing never try to allow your engine to exceed 380, 390 is max. Have faith, I just needs to break in!!

Before I tell you what I got on the stop watch (yes a real stop watch - remember I had been doing Vx and Vy testing down low) I want to remind you that for best rate of climb you should use true airspeed, especially when up high. So using the true airspeed of what I had previously determined was Vy for the demo, it only took me 1:07 to climb the 1000' between 9 and 10 thousand feet. I thought that was pretty amazing - darn near 1000 feet per minute at that altitude. Every good thing comes at a price. Our initial experience with the wing extensions is that they dramatically change the landing angle. the plane tends to "float" with any excess airspeed, and makes landing over an obstacle or into a tight field difficult. Also, at the lower speeds, the airspeed indicator doesnt read very well. Our local builder is debating wether to cut his off!!! Also, the roll is significantly more difficult.

If you want to make shorter hops into grass strips or tight places, then the standard tips may be better. If you need to lower your stall, then use the VGs. Again, this is just initial testing for some Green Landings builders. And it comes from hangar talk. But it would appear there is a down side to the wing tip extensions.

    Peter, Please send photos of your install, we worked very hard to insure that the cowl operates well with the jabiru engine. Even on 100 degree days here in TN with the humidity at 90% we can taxi almost all day long if the cowl is on it and never exceed 350. I would suspect something is up with your ability to get the air out of the cowl and or properly baffled around the cylinders.

    Subject: Re: Lightning Fly-In is just around the corner
    Doug Let me jump in on the new wing tip extensions. I have the first owner bu ilt Lightning with wing tip extensions. I sure like the look, however ev erything you said is true. In the first 40 hrs of flying I pretty will g ot to know them. I have about 30 hrs in the standard Lighting (N838BF) a nd now with 40 hrs in (N123WL) my lightning. The Ailerons are stiffer wi th the long wings. I have tried to change the position of the aileron pu sh rods for more mechanical advantage, but would not get all the throw n eeded to get full aileron deflection. The control stick would hit my kne e first. To help the float on landing I have gone to 40 degrees of flap landings. I put the last 10 degrees in when I slow to 60 MPH on final. The Lightning stalls very hard with airspeed below 38MPH indicated. I am not an expert, but think the tail feathers stall before the wings and m y Lightning will pitch over in a dive. I will loose 300 ft looking strai ght at the ground. I found the stall charistics much different, and very mild in the standard Lightning. If I were building a new lightning I would put the new wing tips on just for show. However I would cut off 6 to 10 inches off the new tips. This would give you 8 to 12 inch tips, instead of 18 inch. This would still give you somewhat slower stall speed and have all the great look of the new tips. Might even help with the aileron stiffness. Remember I am no expert, but this is my 2 cents worth.

    Subject: Lightning Fly-In is just around the corner
    I believe builders and pilots alike must first learn to properly fly the new tips to get the most out of them. The wing is completely different and thus must be flown is such a manner. We will use 50-55mph with 40 flaps on final approach and can get in shorter than was able with the old tips, due of course to the slower speed. Yes if you carry 5-10 extra you will not be able to land as short as you could but again it is a different wing and should be flown that way. The only down side to the tips is not in the performance of the tip but in the way the pilot must fly the aircraft to get the proper results, they must be more attentive to speed. The deck angle should be no different as the angle at which the airfoil stalls is the same but the ability to fly the aircraft slower to reach this deck angle is different. Remember the old at any airspeed, and any attitude a wing will stall, right but the AOA that the wing stalls at will be the same for a given airfoil regardless of length or area. Yes the roll is slower but not any less responsive, and again if you want to do rolls this is not the aircraft for your mission. If your ASI doesn't work that low get a better one, the Sport EFIS has no issue reading accurately to 30mph and the aircraft at gross stalls around 38IAS with 40 flaps so you should be on the ground before it stops working. We have done pleanty of testing on paved and on grass strips here and a Lightning equipped with the wing tips and correct prop will get off the ground quicker climb steeper and go faster at altitude than one with out. Also it will come in slower and land shorter too.

    Pete, Odd, my #5 is also running hotter than the others. However, getting the idle set correctly did make a big difference.

    Hullo Pete, my CHT are between 240 and 330 F, however my EGT is VERY high and I am working on them. To answer your question, first place the "v" plates below, I have also made glass ramps to the inlets to get a better air flow, last week I also did the sump mode and that made my oil temp acceptable, now if I could just get the EGT's down Anthony Morrison kit 32 -----Original Message----- From: owner-lightning-list-server@matronics.com [mailto:owner-lightning-list-server@matronics.com] On Behalf Of ryan gross Sent: Thursday, 25 September 2008 10:32 PM Subject: Re: Lightning-List: CHT Pete, It is not advised to do much taxi testing or ground run ups with your new Jabiru engine.

    Subject: Re: CHT
    Thanks Ryan, I'm using a "Revmaster" carby 40mm and it is very easy to adjust mixture, even from the cockpit, I could certainly do that. Earlier I had it adjusted, from the cockpit, where from full rich, pulling the mixture back would increase rpm to idle cut-off. I have since adjusted where rpm does not increase when leaning to idle cut-off. Thanks again, I will aim to increase the EGT a bit.

You should get something in the mid to low 1300 on takeoff and about 1400 to 1420 in cruise. This will give you optimal fuel burn and clean spark plugs. I think if you continue to see those number your engine will run rough and you will foul the plugs.

    Subject: Lightning Fly-In is just around the corner
    I am sorry to say I will not make it to the fly-in this year. Truth be told, I am ashamed to show my face due to the almost total lack of progress on my Lightning this summer. No-one's fault but my own. The summer wasn't totally wasted however, as I have increased the plane's passenger or luggage carrying capacity by 14lbs! :-) I hope you all have a great time and learn a lot this weekend. Now that the garage has cooled down, I will be getting back to work. Colin K. OK Lightning # 52 under construction. http://www.mykitlog.com/cojaken -----Original Message----- From: owner-lightning-list-server@matronics.com [mailto:owner-lightning-list-server@matronics.com] On Behalf Of N1BZRich@aol.com Sent: Wednesday, September 24, 2008 11:53 PM Subject: Lightning-List: Lightning Fly-In is just around the corner To all Lightning listers, As most of you know this weekend is the second annual Lightning Fly-In at the Lightning "factory" in Shelbyville, TN. The SYI guys have lots of good things planned for us and will be introducing two new members of their group. Katie is their new "staff" pilot and will be doing both OT&E flights (Phase 1 type stuff) plus she will be flying some of the transition training flights for them as well. I have had the pleasure of flying with Katie on several sorties while here and she is a good pilot that will fit in well with the overall Lightning team. "Cleco" is the other new member of the Lightning group. She has a somewhat "catty" reputation and has been seen trying to rub up on Nick and Mark, and has even been seen sitting on their laps trying to get some attention. I must admit, she is cute little female, but I think Katie is easier to talk "airplanes" to and is just as cute. Now don't blush Katie. Actually the fun has already started as far as I am concerned. I arrived last Thursday and Joe and Linda Mathias got here Tuesday. They are making some mods to their airplane and I have been having a great time doing some performance testing on the recently "reconfigured" Lightning Demo. If you haven't guessed what I am talking about, I am going to "spill the beans" so to speak. Nick liked the new wing tip extensions on the prototype so much that he has retrofitted them to the new demo. I must say I am really impressed. Those darn things are actually faster than the shorter original tips, especially at altitude (about 5 mph at 10,000'), and of course they lower the stall speed, shorten the takeoff roll, increase the rate of climb, and increase service ceiling. The other day (after it got too bumpy for accurate rate of climb test down low) I decided to "go high" just for fun. On the way to 14,000 I decided to time the climb from 9,000 feet to 10,000 feet. Before I tell you what I got on the stop watch (yes a real stop watch - remember I had been doing Vx and Vy testing down low) I want to remind you that for best rate of climb you should use true airspeed, especially when up high. So using the true airspeed of what I had previously determined was Vy for the demo, it only took me 1:07 to climb the 1000' between 9 and 10 thousand feet. I thought that was pretty amazing - darn near 1000 feet per minute at that altitude. It is late, so I will sign off now, but you really need to make it to this Saturday's fly in at SYI. We will be doing lots of demo rides, some formation flying, lots of hangar talk, a few briefings, some skunk works experiments, and there is always the chance of a surprise event. You really need to be here if you are even halfway interested in the Lightning. Blue Skies, Buz _____ Looking for simple solutions to your real-life financial challenges?

I have installed more than 20 jabiru engines and have found that within the first few hours the engine is very vulnerable. At Green Landings in the first days of taxi testing we can only get about 2 to 3 runs down the runway without getting the temperature to hot. If i see the temps rising quickly i will shut down the engine and allow it to cool for an hour or so. Remember heat will build even after the engine is shut off. Also never run the engine on an open cowled system. This will also have the cylinder hot in mins. The best thing to do is find out if your aircraft is stable at just above take off speed and head to the sky. After the climb the engine will cool in level flight. Once you have about 10-15 hours and change your oil at around 25 you will see very noticeable temp differences. After the break in period you will be able to run your Jabiru engine on the ground without any problems. Another thing never try to allow your engine to exceed 380, 390 is max.

    Subject: Re: Lightning Fly-In is just around the corner
    In a message dated 9/25/2008 9:52:15 A.M. Eastern Daylight Time, Kayberg@aol.com writes: Our initial experience with the wing extensions is that they dramatically change the landing angle. the plane tends to "float" with any excess airspeed, and makes landing over an obstacle or into a tight field difficult. Also, at the lower speeds, the airspeed indicator doesnt read very well. Our local builder is debating wether to cut his off!!! Also, the roll is significantly more difficult. That fighterlike quickness is dulled. I must say I am surprised at Doug's comments above and Wayne's agreeing that everything he said was true. You guys are trying to land the new wing tip extension Lightning too fast. In fact Doug states that it will "float" with any excess airspeed. Heck, any airplane will float with excess airspeed - that is what excess means - too much. The amount of float depends on two basic things - how excessively fast you are and how "slick" an airplane is will effect energy bleed off. I have no idea what you mean by them dramatically changing the landing angle, but they stall at exactly the same angle of attack as the short wing Lightning. They both have the same airfoil. I think we all learned that in Aero 101. I have flow both the prototype and the demo with the new tips and I really like the way they fly and the way they land - and it lands just like the short wing version, just slower. Yes, the roll response is just slightly slower (it never did have fighter like quickness). The control response is nice - with the pitch being lighter than 99% of general aviation aircraft and the roll, because of the high aspect wing, being heavier than pitch. As speed increases, pitch stays relatively light, but roll forces increase, once again because of the high aspect wing. I guarantee you, if flown properly you can get into and out of a much shorter runway (with or without trees on the end) with the new wing extensions. Also, the wing with the new extensions still slips just fine if you find yourself slightly high and fast on final. Or as Nick suggested use 40 degrees of flaps if you find yourself high or slightly fast. But what you really want to do is fly the proper speeds in the pattern. And don't fly those wide bomber or airline type approaches. Shoot for 1.3 times the stall speed rolling out on a 1/4 mile to 1/2 mile final and let that speed bleed off over the overrun as you get ready to touch down. And know what a 1/4 mile or a 1/2 mile looks like. How long is your runway? Is is 2,500 feet long (about 1/2 mile); is it 5000' (about 1 mile)? That will help you judge how far out your base should be. And learn to start "seeing" the desired glide path while you are still on downwind. Sorry to sound like I am preaching, but wide patterns and landing too fast are some of the things that bother me. And did I say full stall landing? Please go back to one of the previous Lightning newsletters and re-read the article that Nick and I co-authored about landings. If you disagree with anything in that article or anything I said above, lets talk about it. You know what they say, you can either agree with me or be wrong. Please at least smile at this, I am trying to inject some humor. Today I flew the demo again doing more preliminary ASTM testing for the future SLSA Lightning. I took off with the airplane weighing exactly 1320 pounds, immediately climbed to 5,000 to do heavy weight stall testing. OAT at 5,000 MSL was 66 degrees and the density altitude was 6250'. Clean stall was 52 miles per hour (will be easily below 52 at sea level for light sport). Stall at 10 degree flaps was 48 mph, 20 degree flap stall was 44 mph, 30 degree stall was 42 mph, and 40 degree stall was 38 mph. There was a nice buffet about 3 mph above each stall, and all were straight forward (you must keep the ball centered) except for a slight right roll (I sit on the right side) on the 40 degree stall. Since Lightning recommends using 30 degree flaps for a normal landing your final approach speed should be 1.3 X 42 mph which would be 54.6 mph. Lets make it 55 for an easier number to remember. Yes, you can add half the gust factor for gusting winds, but don't start adding 5 mph for each kid, 5 mph for the bride, and 5 mph because it is the fourth Thursday of the month. Just fly 55 on final and you will find it lands just fine, doesn't float excessively, and certainly doesn't have a "different landing angle" - what ever that is. Heck, I will even let you use 60 on final with no problems getting down and clear of the runway in about 1,000 feet. Guys, I don't care if you have 40,000 hours or 40 hours. If you fly any airplane like we talked about above you will have a great chance of making good landings. Well, maybe not the lunar lander. But my point is -follow the basic rules and you will do fine. Hangar talk is sometimes interesting to listen to, but if it goes against the basic rules of good stick and rudder airmanship, don't put too much credence into it. Again, sorry to get so long winded, but I want everyone to know that his airplane (with or without the new wings tip extensions) flys just fine when flown and landed the way all airplanes should be flown. Yes, they may be exceptions (the lunar lander) but the Lightning is not one of them.

    Have tried bigger jets to no avail; have lifted the floats as high as I can for next flight, if it improves will go to larger jets. Numbers are up to 1500F in cruise (2950rpm) I have 285 needle and 255 main in at the moment, tried 290 needle and 280 main, only ran well with carby heat on no matter what jets were fitted. Beats me!
