    Subject: Re: Fw: Kit No 36 is finally finished.
    Thanks Brian,the injected engine on my jab runs smoother, has more power and is very ecenomical especially in cruise. The lightning engine on ground runups sound good but it has only the base fuel mapping I put in until I can fine tune it when we start test flying. The real advantage of electronic fuel injection is once the maps are set up the air fuel ratio stays the same regardless of atmospheric conditions and altitude. I advised Steve Biele with the electronic fuel injection on his lightning and set up his fuel maps. He uses a different throttle body other than that everything else is the same as my jab and my brothersd lightning. The problem we are currently having with Steve's system is EGT distribution between cylinders. The real problem is the poor design of the jabiru plenum chamber, to over come his problem he will be fittng 6 injectors after christmas and I will be helping him wire it and set up his fuel maps . If people are interested in how to set up a simple electonic fuel injection I would be willing to write a articleand send it to Buz for the newsletter. Cheers Helmut. ----- Original Message ----- From: Brian Whittingham To: lightning-list@matronics.com Sent: Monday, December 07, 2009 12:23 AM Subject: RE: Lightning-List: Fw: Kit No 36 is finally finished. Congratulations to you and your brother Helmut. Looks like you did a really good job. I'd be really interested in hearing more about your fuel injected setup. 350 hours without trouble is a pretty good data point. Perhaps you have pictures and could share the story with Buz to put in a future article? Do you notice anything in particular about the engine after fuel injecting? Does it seem to run smoother, have more power, etc?

Date: Sun, 6 Dec 2009 20:52:40 +1030 ----- Original Message ----- Subject: Kit No 36 is finally finished. We have finally finished this lightning kit after two and a half years of work.There was a lot of frustation but also a lot of pleasure and the end result was very pleasing. The kit belongs to my brother John who did not have the confidence to build so I did the technical side of the work and my brother the the paint work and trimming. The reason for the extended build time was my limited time at my brothers place as he lives over 3 hours drive from my place and we did all the work ourselves no outside help.. I have built 2 Jabiru kits before which are still in our family and used frequently. I fitted a voyager EFIS into the panel the engine is fitted with electronic fuel injection using a Haltech ECU with Jenvey throttle body 2 RX7 injectors. This is the same set up I fitted to my Jabiru when I built it and has run over 350hours without trouble. We are currently doing high speed taxi tests to get used to the toe brakes. Then into the test flying. I have attached a number of pictures.

    Wow! Super looking airplane! I look forward to hearing more about your FI installation and the flight performance on your jet. By the way, what prop are you using? I think you must have the first Lightning with a three blade composite prop. So, when you guys get the chance, I know our readers would enjoy articles in the newsletter on the engine/fuel injection set up and how that three blade prop is working.

You remain a sage of down to earth wisdom. Maybe because of your knowledge that sh*t goes downhill . ;-) Buz In a message dated 12/5/2009 9:45:05 A.M. Eastern Standard Time, Kayberg@a ol.com writes:. This is more of a general response to Bill and others who are considering trying more aggressive maneuvers in their Lightning's. I am not writin g as an expert in aerobatics. I am using several third party anecdotes. It is just my mental compilations. It is what I have heard from "hang ar flying" There seems to be several things that are universal to early attempts at flying beyond the recommendations of the kit maker. 1) Assumptions that a little experience is enough to handle a Lightning. That is OK if one is lucky. I have heard of 4 different pilots, at le ast 2 were former Air Force jet jockeys (not Buz), who tried a sloppy ro ll in a Lightning and ended up going straight down and needed a high G pul lout. The plane saved them because of its strength, but it was not a fu n time. 2) Assumptions that a Lightning is "like" something else, therefore it rea cts the same way. A couple of the previously mention pilots had high per formance aerobatic planes. They still screwed up their first roll. 3) Assuming you wont need to "get out" of the plane if something goes bad. The best case here is the Cessna BugCatcher (SkyCatcher). On two separ ate occasions, during spin testing, two different airplanes became uncontr ollable and ended up crashing. Parachutes saved the pilots, but the poin t is that even experienced pilots with an intimate knowledge of a particul ar airframe can end up badly..... Do you fly with personal rules? A goo d one might be, no aerobatic attempts in a Lightning without A)a canopy re lease and a parachute or B) an airframe chute. Which is why I am impress ed by Bill's willingness to raise the issue in the first place. 4) Assuming the plane's response wont be abrupt. If you read Buz's accoun ts, you may recall he had a flap problem during testing and the plane roll ed upside down ....faster than even he could respond to. You will also no te to ENTER a spin, it was necessary to pitch the nose up at very high ang les. Same for doing departure stalls. If you work at doing aggressive stalls, the plane can also respond aggressively. Remember Buz has a lot of cautions about becoming inverted and entering flat spins. 5) Ignoring the cautions of people who have done aggressive maneuvers. There is a reason the most experienced and skilled pilots of Lightnings dont talk about what they can do in a Lightning. They are afraid someone who overestimates their piloting skills will try it with fatal results. Not because the airplane is unsafe, but it WAS NOT DESIGNED FOR AEROBATI CS!! 6) Not thinking about the effect of their screw up on the "brand". We kn ow what the Feds just did to the Zenair Zodiac XL. It only took a handful of crashes, without a single common cause, out of more than 1,000 flying to "ground" that whole bunch. We have already lost a couple Lightning's with no common cause.... out of a lot less than 1,000 flying. We really need Lightning pilots to act wisely, not just for their sake but for the sake of all of use who love the plane. 7) Not resisting temptation. We all know what it feels like to be buzzing along on a great day strapped in a fine airplane. A few swerves, turns and banks feel good and we think she wants to loop, roll or spin. Take a cold shower first.
