Posted: Sat Feb 28, 2009 7:52 am Post subject: Havasu..Maybe this one's for you, Gary!

I will be in Lake Havasu the last weekend of April for the big Offshore Powerboat race.  Anyone planning to go too?  I am very interested in seeing a lightning.  I have been unable to get away to travel to Gary's to see his.  I am in So. Ca.  Gary, if you have nothing to do on Friday, April 24, and feel like flying up to Havasu (or if you're not too far from there I could drive to you), I'd love to see the plane.  You see I'm pretty sure I want to hoin your fraternity and build one, but I'm not sure I will fit.  I'm 6'4 and #280!  Your thoughts?

Have a blessed day!

Scott;



I am 6'-2" with a very tall torso, (my legs are 31"), and I fit fine in mine.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Hello Scott

  

 Is Havasu big enough for Offshore Power Boats? I would love to see the  races! Also, the scenery will be outstanding! I will seriously consider flying  out there.

  

 If you've read any of my responses on this site, you may remember my  philosophies ... 1) "nothing is perfect" and 2) "everything is a  compromise". That said, "It depends". You have obviously investigated the  Lightning, I assume you like the looks...most people do. It is a great  looking plane and generates lots of interest wherever you go. Everywhere I  fly, at least one person will comment on how good it looks. Most people think it  is a "Lancair". My response is...."No, Lancairs are much slower". Just  kidding. 

  

 Anyway, I am 6'3" and weigh 195 lbs. I cut and lowered my seat pan 1" which  gave me a little more head room. I fit nicely in the seat and it is very  comfortable. If you are 280, you will be snug. I suggest you visit Greg Hobbs in  Marana, Arizona for demo flight or go to Tennessee. Shoulder room is adequate.  Adjustable rudder peddles are handy.

  

 Here is some data on my Lightning. I hope it helps in your decision:

  

      1) Cruise speed (at) 2850 rpm (at)  7000':   133 +/- IAS, 145 TAS (Note: I have read reports from other  builders that they achieve 

                                                            170 mph from their planes. I don't know how they managed it. I wish I knew.  Maybe it

                                                           is  at full throttle.)

      2) Fuel used:   Premium Auto Fuel  or AvGas

      3) Fuel consumption: 3.9 to 4.5 gals/hour (Note:  It burns more AvGas that auto fuel)

      4) Rate of climb: (depending on atmospheric  conditions) 900-1300 fpm with just me in the plane

Hey Gary: My numbers come close to yours. I question your airspeed  indication. If you are 7000 feet you should get an additional 21 mph TAS over  indicated on a standard day. If you are reporting those numbers on a hot Arizona  day, then your density altitude was probably much higher than 7000. Here in  Florida at 2000' today (altimeter 3007 temp 60) this morning I was indicating  133 on 2650 RPM with a true of 140 mph burning 4.2 gph. Not as fast as a  Lancair, but looking just as good. I too get lots of comments from people where  ever I fly about how great the airplane looks. The rest of my numbers go along  pretty well with yours.

Just  in case someone's in the Midwest and wants to see powerboat races, I live right  on the water (at) Lake of the Ozarks, in MO.  There are races and poker runs  here all the time.  If someone wanted to fly their Lightning in, I'd gladly  trade some boat time for airplane time.  :>)  That goes for you  too, Nick (or anyone at the factory).

     I'm  6'2" also with a long torso.  34" inseam, though.  It was a tight fit  for me in the silver demo plane.  I'd want to lower my seat pan  also.

 Gary,

     The 170 TAS that I often get on a long cross  country is certainly not at full throttle.  I am normally up at  10,000' or sometimes even higher, depending on winds and weather.  The  cross county technique that I use is to set the fuel flow that I want and  then accept the rpm and the true airspeed that it gives me.   After my level off, I normally set 6 gallons per hour and, with the prop I have  been using - a 64ZK55, that will usually give the something around 165 to  172 mph true airspeed when at altitudes of 10 to 12 thousand feet.  Of  course rpm varies a little but is normally around 3050 to 3100.  Note my  CHTs, EGTs and oil temps are all well within the green at this setting.  In  fact, all are green right on up through WOT.  

     Now a few other thoughts.  As far as comparing  airspeeds with various props, rpm, fuel flows, etc.  It is always better to  have at least one common point.  Nick and I most always use 5,000' when  doing speed comparisons.  The main reason for picking 5,000' is that you  normally have smooth air when that high  (even in the summer) and of course  you want smooth air so you can trim the airplane up and let the engine run for a  while at whatever rpm you are using so things settle down. (I often use  auto pilot with altitude hold on.)  Another thing we normally do is to use  5,000 density altitude (as either determined by your EFIS or by  you if you know OAT and pressure altitude).  Of course, most of us have the  Grand Rapids EFIS so we always know the exact density altitude, and by always  using the same density altitude for the speed runs you always have good numbers  that are already compensated for when you make runs on different days, even  summer to winter.  

     Now having said that, the 64ZK55 that I have used  for about two years is really not enough prop for my airplane.  I say that  because at 5,000 I can over speed the engine when at WOT.  So pulling the  prop back to 3300 gives me about 183 to 185 mph true.  Some other rpm  numbers to compare at 5000:  2650 gives 136 to 137, 2850 gives 150 to 151,  and 3050 gives about 170.  

     I have been recently doing some new prop test with  a 62FK60.  With this prop at 5,000 density altitude, WOT only allows my  engine to turn up 3200 rpm but that speed is 184 to 185.  2650 gives 145,  2850 gives 160, and 3050 gives 175.  Again, all numbers are at 5,000'  density altitude and are in miles per hour true airspeed.  The down side to  this prop, if I keep it, is that I may need to change the jetting in the  carb as the engine burns more fuel with it.  The fuel differences are not  very large at the lower rpm but steadily increase as rpm goes up such that at  above 2950 to 3000 it is about a gallon more and continues increasing.as  you get closer to WOT.  

     One other thing to remember, the above  performance numbers are with my highly modified Esqual with lots  of clean up mods.  Your Lightning, if built light and straight with good  clean up mods, should actually do slightly better, as the prototype Lightning is  about 2 to 3 mph faster than 31BZ when Nick an I fly them in close formation  with the same props and same rpm.    But as they say, your mileage may  vary.

 Hope this helps.

At about 10000 feet and 2950-3000RPM 170 TAS is possible with the long wing tips.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Hello Buz

  

 Thanks for the response. I also have the Grand Rapids EFIS. One thing I've  noticed though is that the OAT reading is never the same as the reported field  temp. I spoke to GRT about it after finishing the plane. They said it was a bad  sensor so they sent another. It reads the same. I installed the first  sensor in the fresh air intake. The second one I installed inside the gear leg  fairing to avoid temp fluctuations due to engine heat. No change. 

  

 Anyway, higher altitude makes little difference in the IAS and TAS as  indicated by the EFIS at 2850 rpm. As I noted, the steam gauge ASI reads  identical to the EFIS for IAS  With the prop that Nick sent, my engine will  turn max +/- 3000-3100 rpm. It is my understanding that the max continuous rpm  is 2850. Due you commonly run higher and if so, isn't that hard on the  engine?

  

 I don't know what else to say. At between 6000'-9000' and 2850 rpm, IAS is  approx. 134 mph and TAS is about 144 mph....according to the gauges.

  

 Thanks again.

Your Numbers are right on.  Buz has a Different engine that produces more power and a different wing.

 Thanks for the response. I also have the Grand Rapids EFIS. One thing I've noticed though is that the OAT reading is never the same as the reported field temp. I spoke to GRT about it after finishing the plane. They said it was a bad sensor so they sent another. It reads the same. I installed the first sensor in the fresh air intake. The second one I installed inside the gear leg fairing to avoid temp fluctuations due to engine heat. No change. 

  

 Anyway, higher altitude makes little difference in the IAS and TAS as indicated by the EFIS at 2850 rpm. As I noted, the steam gauge ASI reads identical to the EFIS for IAS  With the prop that Nick sent, my engine will turn max +/- 3000-3100 rpm. It is my understanding that the max continuous rpm is 2850. Due you commonly run higher and if so, isn't that hard on the engine?

  

 I don't know what else to say. At between 6000'-9000' and 2850 rpm, IAS is approx. 134 mph and TAS is about 144 mph....according to the gauges.

  

 Thanks again.

 Good point, Wayne, I do have one of the old solid lifter engines.   However, remember the latest hydraulic lifter engines have the new cam profile  that should get the power/rpms back.  Also, I think the Lightning wing  with the extended tips is a slightly faster wing than I am using.

I do not see the speeds you have.  I think Gary and My Lightning will fly side by side in Cruse.

 These latest speeds are with the 62FK60 prop and more than likely you have  a 63FK58 prop.

 Typo - meant to type 62FK58.  A 62 diameter, not  63.

 ALL,

 Just a comment about Buz's speeds.  Or Nick's for that matter.

  

 If you have see his bird, you will understand that it has near perfect fit  and finish.   Nothing hangs out in the air causing a  disturbance.  The evidence for that is related to the rpms he is turning to  get those speeds.  Not only  is he running a prop with a lot of pitch,  but he is also able to turn it up to 3300 rpms at WOT and altitude.

  

 My observation is that it is easy to get a less that perfect fit of wing to  fuselage,  sloppy fairings and mis-fited wheel pants.   All that  makes a difference.

  

 Further evidence is that he has Esqual wing which is slower and has higher  lift at low speeds than the Lightning wing....or at least what I have  observed.

  

 Pardon me for repeating this, but I think the prop selection has even more  to do with speed... I think it is possible to get a 10-15mph speed variation  just by having a slightly miss-matched prop.  

  

 I would further note that Buz's solid lifter engine is well broken  in!!    I think it can take 100 hours of proper break-in to get  the compressions up and even.  All that makes a difference also.   

  

 Not to mention that he is running 100LL.   Perhaps at economy  settings, mogas will deliver economy, but I doubt it will deliver the  POWER.  Fuel flow varies depending on where the carb needles are positioned  and the set up of the jetting.  Buz and Nick have carefully matched the  jetting to the prop.

  

 In my opinion, the max speeds possible in a Lightning are achieved with  some serious tweeking and serious attention to detail, AFTER achieving max  performance with engine and prop.

  

 If you are mostly a fun pilot who makes short runs on weekends as a stress  reliever,  some obsession with max speeds may be  counter-productive.

Perfect fit and finish is a must but if you have seen either garys or waynes they are darn close, real good looking aircraft.  I hate to throw a wrench into your theory but the prototype, again with many hours on her and a solid lifter engine. Is equipped with buddys old wood prop that we could only get 2550 or 2600 on takeoff with his, easily turns to 2800-2900 on take off by the prototype. Speeds above 150 IAS are easy at 5k.   

A lightning which just went home to FL was running 162TAS (at) 8k with 2950 turning. Those are performance numbers we got before it left and what it was running on the way down.
