 |
|
Yesterday I flew two flights in the current demo Lightning with the new larger stab and to say the least, I was very pleased with the flying characteristics. My concern was that the larger area stab would (please excuse the term) "dumb down" the wonderful overall sporty feel that the Lightning has had from day one. No worries, it still has that great sporty Lightning feel when flying around enjoying your "jet". But I can also happily report that the new stab makes the takeoff and landing feel in pitch to be much more solid and less quick reacting, so Nick's latest mod has removed any concerns about longitudinal pitch stability that some folks might have had when initially checking out in the Lightning. So the bottom line is that this mod makes a great airplane even better.
A few other observations from my flights yesterday. First, on both clean and dirty stalls, the nose is not as high when the stall occurs and the stall itself is not as brisk. You still get the "pre-stall buffet" about 3 to 4 knots before the stall and then recovery is just as quick or maybe even quicker. Also, the new larger stab should result in a slightly increased CG envelop, but I don't have the actual numbers for that.
So for those of you with flying Lightnings, do you want to order the kit for the larger stabilizer? The kit itself is actually a carbon fiber "cuff" that fits over the existing stab and it is then epoxy glued in place. Not too difficult or time consuming except maybe for the finishing and painting. Of course, the Lightning guys can do the mod for you if you don't want to tackle the job yourself. So the decision to mod your Lightning with the new larger stab really depends on you and the way you like the way your "jet" feels on takeoffs and landings. One other consideration might be if you ever decide to sell your Lightning, you will be able to say that it has the latest mod that was developed by the factory for the current LS-1.
Blue Skies,
Buz

Wish we were there. Discovered some nose gear issues when doing
preflight. Tried calling Mark at Arion but you all are too busy having fun
for him to respond. Looks like I need a new nose gear socket and nose
gear block. Squawk is hard to detect if it wasn't for the pealing paint the
wife saw. Upon inspection we found what appears to be bent nose gear
socket and a cracked phenolic nose block.
Oh well... Hope everyone has fun.. Will see you at next years homecoming!

Thanks for writing that up. My Lightning has always been squirrelly on landings! Greg Hobbs is in the process of changing out the tail on my Lightning while it is in Arizona. Your impressions of the revised tail flight characteristics are timely, very helpful and appreciated. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
On a different but related subject, when watching a video of Nick landing the Lightning LS-1 I noticed it lands very flat with nose wheel barely clearing the ground. That characteristic is common in high aspect ratio sailplanes that use only flaps for glide path control. When talking to Greg about this he mentioned that one of his homebuilders had shortened his nose strut by 1 ¾ inches to improve nose wheel ground clearance on landing. Greg suggested we try shortening mine by at least ¾ inch for a trial. You can do ¾ inch without cutting the nose strut where it would contact the firewall. This allows for a little faster landing without the nose wheel touching first and causing a PIO to start. If it works out well I will try the extra inch later. Thanks again, Gary, N335AL Sn 133

Hi Buz and Lightning/Esqual friends.
Any chance to have a picture and/or the size of the new stab ?
Beyond the answers given and the results obtained I would like to know it to calculate the relation between wing /stab area and other parameters and phougoid dumping being mandatory to change the center of gravity to obtain the best results
Thank you.

Hi Luigi,
I did take some photos of the new stab and will post them when I get a chance to download them off the camera. I am not sure of the increased area but I'm sure Nick will answer that question for you. He has also already calculated the ratio of the wing and new stab area and can provide that as well.
The cuff that they designed to fit over the original stabs really makes the mod relatively easy to upgrade. The cuffs are made of carbon fiber and will add about a pound to each side. Of course new Lightning kits will come with the new larger stabs as part of the kit or a completed SLSA LS-1, so no need to modify the new Lightnings.
I am headed back to Virginia today and hope to get caught up on emails then as well as posting some photos of the new stab and cuff.
Blue Skies,
Buz

The attached PDF file has the photos I took of the new larger stab and the basic installation process. Hope this helps.

Yes, I did. Long day, but got home just after 7 PM. Good get together since I got to do lots of flying in three different airplanes - new demo Lightning with larger stab, Zenith 750 with 3300 Jabiru, and RV-12 with 2200 Jab. I had flown the RV-12 before, but wanted to get more time in it as I will probably make the first flight for a guy in Newport News that is building one. I've been making the tech counselor visits and he is doing a super job.

Oggetto: Flying the new larger stab.
Yesterday I flew two flights in the current demo Lightning with the new larger stab and to say the least, I was very pleased with the flying characteristics. My concern was that the larger area stab would (please excuse the term) "dumb down" the wonderful overall sporty feel that the Lightning has had from day one. No worries, it still has that great sporty Lightning feel when flying around enjoying your "jet". But I can also happily report that the new stab makes the takeoff and landing feel in pitch to be much more solid and less quick reacting, so Nick's latest mod has removed any concerns about longitudinal pitch stability that some folks might have had when initially checking out in the Lightning. So the bottom line is that this mod makes a great airplane even better.
A few other observations from my flights yesterday. First, on both clean and dirty stalls, the nose is not as high when the stall occurs and the stall itself is not as brisk. You still get the "pre-stall buffet" about 3 to 4 knots before the stall and then recovery is just as quick or maybe even quicker. Also, the new larger stab should result in a slightly increased CG envelop, but I don't have the actual numbers for that.
So for those of you with flying Lightnings, do you want to order the kit for the larger stabilizer? The kit itself is actually a carbon fiber "cuff" that fits over the existing stab and it is then epoxy glued in place. Not too difficult or time consuming except maybe for the finishing and painting. Of course, the Lightning guys can do the mod for you if you don't want to tackle the job yourself. So the decision to mod your Lightning with the new larger stab really depends on you and the way you like the way your "jet" feels on takeoffs and landings. One other consideration might be if you ever decide to sell your Lightning, you will be able to say that it has the latest mod that was developed by the factory for the current LS-1.
Blue Skies,
Buz

Luigi,
The attached PDF file has the photos I took of the new larger stab and the basic installation process. Hope this helps.
Blue Skies,
Buz

Any chance to have a picture and/or the size of the new stab ?
Beyond the answers given and the results obtained I would like to know it to calculate the relation between wing /stab area and other parameters and phougoid dumping being mandatory to change the center of gravity to obtain the best results
Thank you.
Regards from the Old World

Interesting development. Does the enlarged tailplane have any effect on the stick free longitudinal stability at cruise speeds?

Ah, forget that, I just found the description a few threads down. I'll post some more in that.
