Flying the RDD LX7

I get to fly a lot of different airplanes in my chosen career. There aren’t many airplanes that I take off in, then say “Wow,” and have a big smile on my face. The RDD LX7 was definitely one of those.

I wrote about the RDD LX7 in the past, bragging about everything I read about it. The blogs all advertised 250 KTAS and 17 GPH and FL250, all of which are eye popping numbers.

Lo and behold, those numbers are true.

I got to go up to RDD’s Redmond, Oregon facility in April 2021 to get my initial training in the RDD LX7 and I couldn’t wipe the smile off my face. The 3 screen G3X Touch layout is very impressive and not crowded like I thought it would be. Being familiar with the G500TXi, there are some G3X specifics that take a little getting used to, but overall, it’s a good system. The main GPS and number 1 radio is a GTN 750Xi.

We took off from RDM and proceeded to climb at 140 KIAS, which equated to 2,000 FPM. We only had half tanks (which is still 90 gallons of fuel!), but it climbed with no problem. It’s extremely responsive as I learned while doing the basic flight maneuvers. The stall speed of the airplane (the biggest problem with the Lancair 4P, the airframe that the RDD LX7 is derived from, was the terrible wing design and extremely high stall speed), was in the low 60s or high 50s, with the stall being extremely docile.

The airplane handled very similarly to a Columbia 400, but seemed even more responsive. The glide ratio isn’t as good as some, but it’s still better than a Cirrus (plus it still has a BRS system to boot).

The big test was the flight to San Antonio from Redmond to bring the plane home. The new owner and I departed RDM with the tanks full of Avgas (180 gallons), then got up to a cruise altitude of FL210. After setting power and leaning, the numbers came out true to spec: 252 KTAS, 17.5 GPH.

The greatest part? We stopped in Santa Fe to stretch our legs and we didn’t need fuel. We still had 100 gallons left! That left us plenty to get to San Antonio with 40-50 gallons left over. Another RDD LX7 owner flew his piston direct from Redmond, OR to Jacksonville, FL, non-stop. It was over 9 hours. That’s impressive.

You can’t beat the purchase price, either. A new Cirrus SR22T runs a little north of $1.2m. A piston engine LX7, that is pressurized, 70 KTAS faster with a much longer range, and still has a BRS, is between $850,000-$900,000. An LX7 starts to make a whole lot of sense when you weigh all that. There is also a PT6 option with several different sizes and horsepowers to choose from, which costs more, but you see 300 KTAS.

  • Jet A Fueling Mismanagement

    I’m sure at this point, most pilots in Texas have heard about the Cessna 421 that went down two weeks ago in Lufkin.  The Golden Eagle suffered a dual engine failure (the pilot lost the first at 2300 feet, then the second at 1700 feet) in IMC on climb out.  He broke out at 1,000 AGL miraculously lined up with US 59, south of the Lufkin airport.  The pilot had to dodge a car as he was attempting his landing, stalled the airplane, sheared off the landing gear, then slid into the median.  No one died, but lots of bumps and bruises.  All were airlifted to Houston.

    Jet A Lufkin Plane Crash

    The cause was a lineman at LFK put Jet A in the 421, which is a piston airplane and takes 100LL Avgas.  The story that I saw said the pilot and two passengers were returning to Houston from Kansas City and diverted to LFK due to weather.  They landed in driving rain and spent the night.  I have not seen any reports saying whether the pilot sumped the tanks or not the following morning.

    There were several factors that led to this accident.  If you take one factor out, the accident probably wouldn’t have happened.  Let’s take a look at the sequence of events.

    The 421 arrived in a driving rain storm, so the pilot and passengers probably disembarked quickly to get out of the weather.  Factor number 1 presents itself here.  We don’t know whether or not the pilot told the lineman to put Avgas in it or not (he may have just said fill it up), so we’ll leave that aside.

    Understandably, the pilot dashed inside to get out of the rain, but they neglected to monitor the fueling.  Whether or not the fueling took place that night or the next morning, we can’t say.  I have started to greatly encourage my customers to monitor the fueling of their airplanes, especially when it’s a fuselage that can either have Avgas piston engines or Jet A turboprops, as is the case with the Cessna 421.

    Factor number 2, we already know about.  The lineman messed up and put the wrong fuel in.  If their was uncertainty about what type of fuel, he would have been prudent to await the return of the pilot to ask, even if that meant delaying the pilot’s departure.

    Factor number 3 is the matter of sumping the fuel.  We don’t know if the pilot sumped the fuel or not. The tricky thing about sumping is Jet A doesn’t settle out of Avgas like water does unless it sits for a long, long time.  The two ways to determine if you have Jet A in your Avgas airplane are to smell it, as Jet A has a very strong diesel smell, or do the paper towel test.  The paper towel test consists of dumping a fuel sample onto a paper towel, then let the Avgas evaporate.  If you are left with a nasty, oily residue, you’ve got Jet A in your tanks (not to mention it will smell like diesel).

    To prevent misfueling of your airplane, take the following steps:

    • Be specific in telling the lineman what type of fuel you want, not just “fill ‘er up”
    • Monitor the fueling and watch which truck pulls up to your airplane
      • This is especially important with fuselages that can have either Pistons or Turbo-Prop engines, like the PA-46 line or the Twin Cessna line
    • Always sump your fuel, definitely smell it, and if there are any doubts, try a paper towel test

    Airplane Covers

    If you’re going to be leaving your airplane outside at your destination, make sure you have proper covers and plugs to protect it while you are gone. A friend of mine forgot to put his pitot cover on his airplane while it was parked outside and had his departure delayed because of a mud dauber which had moved in while the airplane sat on the ramp.

    Tie-Down Ropes

    Depending on your destination airport/FBO, there may or may not be tie down ropes available on the ramp. It isn’t uncommon for there to be tie down loops, but no ropes. I generally try to carry a set of ropes in the airplane and even my own set of chocks. If you are going to a fly-in or landing at a private strip, steaks with tie down ropes can be very useful as well. Don’t forget to take your ropes and chocks with you when you leave, though. Ropes and chocks which are left unattended can cause problems for airport machinery (plows) and other airplanes.

    Paper and a Pen

    Back to basics! Don’t forget to bring a pen/ pencil and something to write on to keep track of clearances and frequencies.

    EAPIS/ Boarder Crossing Procedures

    If you are planning to fly across the U.S. Border, you will need to have filed the proper paperwork and make sure to bring along your passport/greencard. If you want to fly into Canada everyone on board the airplane is required to have a passport.

    Basic Tools

    You never know when you may need a screwdriver or some pliers. Having a small toolbox which you can throw in the airplane could be a life saver.

    GPS

    If you have a GPS, make sure that your data base is up to date.

    Camera

    Pretty self explanatory…but, don’t forget the camera charger!

    Currency

    Look through your pilot logbook and the airplane logbook and make sure that everything is up to date. If you need to get an IPC or a BFR done before you leave, give yourself some buffer time in case you have to reschedule.

    Other Considerations

    Sometimes it makes sense to go to a larger airport despite having to pay additional fees and higher gas prices. Often, if I am traveling at night or after regular business hours, it is worth the extra expense to know that there will be assistance available should I need it. It also isn’t always necessary to get a hotel…there are airports such as Noble County, Ohio (I10) that have beautiful campsites available on the airport. If you like camping, it can be a fun alternative to shelling out the cash for a hotel and rental car.
    Camping out next to the airplane can be a fun way to spend the night.

    Finally, I like to take the airplane out for a short flight and make sure that everything is working properly before I bring the family and get everything loaded up. (Plus, it’s a perfect excuse to go for a little joyride.) I’d much rather find out that the battery is dead or the plugs are fouled when I have time to fix the issues. If possible, do your test flight on a day when your maintenance shop is open so you can get any problems addressed immediately. If you haven’t done much cross country flying or if you are a little rusty, ask a flight instructor or another pilot to look over your planning. There is also nothing wrong with having an instructor or experienced friend come along on the first few trips until you become more comfortable doing it on your own.

    In my opinion, cross country flying is one of the most rewarding things a pilot can do with their certificate. The view available from the window of a general aviation airplane is so different than the one you get out the window of a car or a commercial airliner. If you’re willing to invest the time and money, you’ll get a lot more out of your trip than a few hours in your logbook. So, what are you waiting for….haven’t you always wanted to go to Oshkosh?

  • Cirrus Pilot Proficiency Program (CPPP)-Conroe, KCXO

    The Cirrus Pilot Proficiency Program is coming back to the Lone Star Airport in Conroe, TX (KCXO) on October 23rd-25th.  Wondering what the CPPP program is?

    “CPPP offers a weekend event for Cirrus owners and their partners that focuses on Cirrus-specific knowledge and flying proficiency.  We bring some of the most experienced flight instructors who regularly teach in all kinds of Cirrus airplanes flown for all kinds of missions.  We have prepared an extensive syllabus of ground courses that complement the transition training and delve into areas of greatest need for Cirrus pilots.” (from CirrusPilots.org)

    CPPP

    The weekend starts off with a group dinner on Friday night. The Saturday morning ground session focuses on General Aviation Safety with special focus on the Cirrus accident statistics.  Normal and emergency procedures are also reviewed.

    In the afternoon on Saturday, the attendees are split into two groups.  The first group has a myriad of options for ground sessions covering all topics related to Cirrus aircraft and operations.  The second group flies, then they switch for the second 3 hour session.  Sunday brings the same split, with more courses offered and more flying.

    While the Cirrus pilots are flying and learning more about their airplanes, CPPP offers a Partner in Command course for flying partners on Saturday.  This allows flying partners to be more comfortable in the airplane and teaches them what to do if something were to happen to the pilot.

    All in all, attending a CPPP will improve both Cirrus knowledge and Cirrus flying skills.  It’s highly recommended for all Cirrus pilots.

  • Cirrus SR20 vs. Diamond DA40

    Note:  For this article I am comparing a 2008 Cirrus SR20 G3 and a 2008 Diamond DA40 XLS.

    Aircraft shopping can be a tedious process.  First, a buyer needs to know what the mission is.  How far will flights typically be, how many people will be on board, and how fast does the airplane need to be.  Then, the buyer has to figure out what the budget is.  Finally, a prospective owner needs to figure out how much airplane he or she can handle.

    Two very good airplanes for newer pilots transitioning from a flight school 172 who need a faster airplane to build experience in, but also want to experience a glass panel, are the Cirrus SR20 G3 and the Diamond DA40 XLS.

    Cirrus SR20 G3

    The 2008 Cirrus SR20 G3 is a good airplane.  The G3 is equipped with the 6 cylinder, Continental IO-360-ES, 200 HP engine.  Performance-wise, an owner can expect 135-140 knots true at 9 GPH (Lean of Peak) or 145-150 knots true at 11.5-12 GPH (Rich of Peak).  The 3 blade propeller equipped models have better takeoff and climb performance than the 2 blade propeller equipped planes, especially in high density altitude conditions.

    Cirrus SR20 Comparison

    The airplane is equipped with the Avidyne Entegra EX 5000 glass panel system.  Most models out there will have Avidyne’s CMAX (Chart View) and all will have the Avidyne EMAX (Engine Monitoring).  All came from the factory with the STEC 55x autopilot (though a handful will have the STEC 55 SR, which doesn’t have glideslope functionality).  They also came from the factory with dual Garmin 430s. Most units have been upgraded to WAAS.

    Some owners have upgraded the autopilot to the Avidyne DFC 90, which is a nice upgrade.  The STEC 55x is a rate based autopilot which takes it’s commands from a hidden turn coordinator that is behind the instrument panel in front of the co-pilot’s seat.  The STEC has some crosswind limitations on approaches where the pilot can actually fly better than the autopilot.

    The DFC 90, however, is an attitude based autopilot that  takes it’s commands from the attitude indicator on the Primary Flight Display (PFD).  It also adds a Straight and Level button as well as an Indicated Airspeed hold button, adding safety and functionality.  It does much better in crosswinds on an instrument approach then the STEC.

    A select few SR20s have been upgraded to a single (or dual) Garmin GTN 650 touch screen GPS unit.  The GTN 650 is a very nice upgrade.  The Garmin 430 is a great unit, but the learning curve with the GTN 650 is much less.  The touch screen setup makes a little more sense to the new user.

    Values on the 2008 SR20 G3 with 1,000 hours or less run somewhere between $220,000-$260,000, depending on total time and equipment.

    Diamond DA40 XLS

    A handful of 2007 XLS DA40s were made, but not many.  Most XLS models you will see are 2008 and later. These are equipped with the Lycoming IO-360, 4 cylinder, 180 HP engine with the Powerflow Exhaust STC. Due to the Powerflow Exhaust, the performance is equal to the SR20.  At 6,000-8,000 feet, you will routinely see 140 knots true at 10-10.5 GPH.  Higher altitudes will give slightly better performance and lower fuel burn.  Like the SR20, the Diamond DA40 XLS comes with either a 2 blade or 3 blade prop.  Go with the 3 blade as the takeoff and climb performance is much better.

    Diamond DA40 Comparison

    Where the DA40 XLS has a leg up on the 2008 SR20 G3 Avidyne is in the avionics.  Diamond got on the Garmin G1000 train a little sooner than Cirrus did and the XLS is equipped with the G1000 and GFC 700 autopilot.  The Garmin GFC 700 autopilot is the best GA autopilot I have flown with.  It is an amazing piece of equipment.

    Most, if not all, DA40 XLS models will have both WAAS and Synthetic Vision.  Cirrus didn’t get Synthetic Vision till they put the Cirrus Perspective by Garmin in their aircraft in the middle of 2008.

    The DA40 has great visibility due to the massive amount of glass surrounding the pilot.  The big glider wings give it excellent pop off the runway, but quite a different climb pitch attitude than most other piston single engine airplanes.  The airplane does like to float on landing if the pilot doesn’t get the speed right.

    Values on the 2008 Diamond DA40 XLS equipped with the Garmin G1000 are around the low-mid $200,000 range.

    Comparison

    Performance wise, the airplanes are about equal.  Rich of peak, the Cirrus out performs the Diamond, but uses more fuel.  Both have about 5 hour ranges (though the Cirrus has bigger fuel tanks, 56 gallons usable compared to the Diamond long range tanks of 50 gallons usable).  Useful load is slightly better in the Diamond due to the fact that the Lycoming engine has 2 fewer cylinders than the Cirrus.  The Cirrus does have a roomier back seat, a larger baggage area, and a side stick instead of a center stick, but the DA40 has a back door.  The Cirrus also has the CAPS system, though an owner has to do a $15,000 repack every ten years.  Airplane values are about the same.

    I give a slight edge to the Diamond, though, and here’s why.  For about the same price, a purchaser can get the Garmin G1000 system complete with the GFC 700 autopilot in the DA40 XLS.  The Avidyne and STEC system is great, but the Garmin system is definitely above and beyond.  To get the Garmin G1000 in an SR20, you’d have to look at the Cirrus Perspective by Garmin, which came out in late 2008, and you’d be paying $300,000 or more for a single engine piston with 200 HP (though you do get Air Conditioning!).

    So for my money, I would go for the Diamond DA40 XLS.  I believe you get a little bit more bang for your buck and you don’t lose anything with the DA40 XLS.  Don’t get me wrong, I love the Cirrus, but comparing the two, I think the Diamond DA40 XLS rates a little higher.

  • IM SAFE: Are You Really?

    As pilots, we are all familiar with the IM SAFE acronym that the FAA puts out.  It comes up as part of the ground training over Human Factors during private pilot ground school.  We all memorize it, spit it out for our check rides, then most of us promptly forget about it.

    When I was training for my pilot’s licenses, I was at a Part 141 school that was very standardized (LeTourneau University, who has a fabulous aviation school).  Before each flight, we had to do a self evaluation based on the weather and the IM SAFE checklist.  Based on our answers, we would then determine if the conditions were conducive to flying as well as if I was physically okay to fly.

    This was a great tool because not only do pilots have to pre-flight the airplane, they also need to pre-flight themselves.  It’s very easy to fall into one of the “Hazardous Attitudes” if there is a pressing meeting or you haven’t flown in a while and it’s a beautiful day, but maybe you aren’t physically fit to control an airplane.

    Let’s break down the IM SAFE checklist to dig a little deeper into the physically fit side of flying.

    Illness

    This one is pretty easy.  Are you sick?  If so, how sick?  If you can’t hardly talk or your body feels like it was hit by a truck, then flying probably isn’t in your best interest.

    The tricky area can become if you are only a little sick.  Maybe you have a cough or a little cold or a headache is starting to form.  You probably could go fly, but is it really a good idea?  It could be something worse, or it may be nothing.  You have to know yourself and put limits on yourself before you wake up on the day of your big meeting two states over.  Set illness personal minimums and stick to them.

    Medication

    There are a slew of drugs, both prescription and over the counter, that pilots cannot take and fly.  AOPA has a hotline to call for pilots to find out if they can fly with the medication they are taking, or what meds they can take to give them relief and still operate an aircraft.

    Another great resource is your medical examiner.  Just give him/her a call and they will be more than happy to let you know what you can and can’t take.  They’ve been educated in the area of aviation so they are very knowledgeable.

    Stress

    StressometerThis is a huge one that pilots ignore a lot.  Maybe it was a stressful day at work, maybe you are running late to the airport, your meeting got moved up, whatever.  Stress can jump on you and mess up a pilot’s thinking very quickly.  If you have a lot of other things on your mind and you aren’t able to focus just on flying, it might be a good idea to stay on the ground.

     

    Alcohol

    Out of the whole IM SAFE list, the alcohol limitations are very clearly defined.  8 hours bottle to throttle, no more than 0.04% BAC, no operating an airplane while under the influence, and no carrying passengers who are visibly intoxicated.  For your personal minimums, it’s a good idea to increase that time to 12, 18 or even 24 hours bottle to throttle.

    Fatigue

    Learning to fly while a college student led to a fair share of canceled flights due to fatigue.  I operate best on 8 hours of sleep in the past 24 hours.  I can function on 6, but anything less than 6 hours, my performance drastically drops off, sometimes to a point where I wouldn’t be safe.  I discovered this while with my flight instructor attempting to do a holding pattern and completely botching it up.

    I observed this as a CFI quite often.  If I was doing ground with a student and they were struggling, my first question would be, how much sleep did you get last night?  More often than not, if I had to ask that question, I would get an average answer of 3 to 4 hours (I even had one guy show up for a flight block on 2 hours sleep.  I sent him back to the dorm).

    Fatigue is very easily overlooked because it’s not measurable.  Needing to get a flight lesson done or needing to get somewhere when you are obviously fatigued is not a good idea.  Make sure you get a good night’s sleep before a flight and don’t be afraid to cancel if you didn’t.  Set some sleep personal minimums and make them hard and fast.

    Eating

    Don’t skip meals and fly.  Performance greatly decreases when a pilot is hungry.  At the very least, stick a couple of food bars in your flight bag to give you some nourishment.

    Also, stay hydrated, especially in the summer time.  I carry a huge bottle of water with me on all my flights because I get headaches if I don’t drink enough.  Getting dehydrated on a long flight can lead to all sorts of performance problems (over hydration is also a problem in the air, but that’s what Gatorade bottles are for, right?).

    All this to say, have some personal minimums when it comes to you and your body.  Check the plane, check the weather and check yourself.  If anything falls in the “red” area in any one of those three categories, stay on the ground and don’t press your luck.

  1. Hank thanks for review of the the LX7! How difficult (costly) is this airplane to insure? Also i am a 300 hour instrument rated PP with 200 of those hours in a G1000 Columbia 400. Would you go the PT-6 route or the Piston for me? The slow flight characteristics of this plane make it seem very reachable for me.

    Thanks,
    Charles.
