Flying the RDD LX7

ByHank Gibson

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.

  • Casey Aviation Makes Piper PA46 Systems Videos Free

    ByHank Gibson

    The safest pilots are the ones who attempt to gain as much knowledge and learning about their airplane and environment as possible. These pilots are the ones who enjoy learning, going to seminars and conventions, and soak up all the MMOPA magazine articles in each issue. These pilots are the ones who get as much training as they can, above and beyond what the minimum requirements are.

    If you are one of these pilots and you own a Piper PA46, then this blog is for you.

    Casey Aviation, one of the best Piper PA46 training companies out there, recently released all of their Malibu, Mirage, Matrix, Meridian, and JetProp systems training videos for free. These are some fantastic videos that Casey Aviation created which go much more in depth than any power point presentation could.

    The great thing about the videos is they give the viewer an all access “inside look” to the specific airplane. Joe Casey, owner of Casey Aviation, takes off cowlings, crawls under the nose gear compartment, and even shows an airplane with the interior out so all the flap cables and environmental systems can be seen.

    I have started referring all of my PA46 customers to the Casey Aviation videos as part of the prep work for our training sessions.

    To access the videos, check out the Casey Aviation website.

  • Piper PA46 De-Ice Boots Care

    ByHank Gibson

    It’s winter time, which means it’s time to use those Piper PA46 de-ice boots a little more often. Most of us know the winter flying rules, don’t stay in ice, get rid of frost, etc. However, most of us aren’t as familiar with how to maintain those Piper PA46 de-ice boots. The do need some TLC every couple of months to keep them in tip top shape.

    Below is the recommendation from Goodrich (the maker of the boots) on what to use to clean and polish the boots and how often to do it.

    Steps 1-3 below are your twice a year items to make your Piper PA46 de-ice boots last through the lifetime of the aircraft.

    Step 1-ShineMaster Prep

    ShineMaster Prep strips all the dirt, grime, grease, oil, silicone products and old ShineMaster on the Piper PA46 de-ice boots to prep them for Step 2.

    ShineMaster Prep can be found on Goodrich’s website.

    Step 2-AgeMaster #1

    AgeMaster is your second step the in the Piper PA46 de-ice boot preservation and protectant process. AgeMaster is a rubber preservative that protects against weathering, ozone, and ultraviolet rays.

    Make the first application when your de-ice boots are 6 months old, then re-apply every 150 hours (or twice a year) after that.

    AgeMaster #1 can be purchased on Goodrich’s website.

    Step 3-ShineMaster

    Step 3 in the Piper PA46 de-ice boot care is ShineMaster. As the name implies, ShineMaster shine’s the boots up after getting rid of all the old gunk & grime with ShineMaster Prep and after AgeMaster is applied. 2-3 coats should be sufficient.

    ShineMaster can be purchased on Goodrich’s website.

    During icing season, Goodrich recommends ICEX II. ICEX II is an ice inhibitor that should be applied every 50 hours during ice season. This will help prevent ice from sticking to the Piper PA46 de-ice boots. ICEX II can be found here.

    Finally, for general cleaning of the boots after each flight, utilize Goodrich Aerospace Cleaner to debug, then follow up with Goodrich Aerospace Protectant. Goodrich claims their Protectant will resist dust, soiling, and staining. There may be less bugs to clean each time!

    With just a few hours a couple times a year spent working on the Piper PA46 de-ice boots, owners will never have to worry about the hefty price tag of boot replacement!

  • The Flight Director as a Backup

    ByHank Gibson

    I’ve noticed that a lot of general aviation pilots tend to ignore the flight director on the attitude indicator.  A lot of pilots don’t even know what it’s there for or how to use it.  Talk to any airline pilot, though, and he or she will tell you how important the flight director actually is.

    In most high performance airplanes, the flight director comes on when the autopilot comes on.  Essentially, the autopilot is following the flight director, which tells the autopilot where to go.  The flight director can also be used with the autopilot off, when hand flying an approach, for example.  By turning the flight director on, it will show you where you need to fly to stay on course and on glide slope.

    Flight Director

    The flight director is most often controlled by the autopilot controller.  The same buttons you use to put the autopilot in heading mode also tells the flight director to follow the heading bug when the autopilot is off.  When you move the heading bug (or change course on the GPS, depending on which mode you have selected), the flight director will show you when you need to turn and when you need to stop turning.  It directs your flight attitude, hence the name.

    I recently discovered it’s a great backup when you have some instruments on the fritz.  I went on a long flight in a steam gauge Piper Malibu and the attitude indicator started reading erratically.  While flying straight and level, it would randomly indicate that I was in a 10 degree bank to the right, swing back and show wings level, then show a 3 degree turn left.  This went on for a while.  We were in VMC conditions, so legality wasn’t a problem, but it was kind of disorienting.

    After a little while of this, the autopilot started acting up.  It would start oscillating the pitch up and down, making it seem like we were going through a moguls course in the air.  I ended up turning the autopilot off and hand flying the airplane.

    This led to a conundrum, since my attitude indicator was unreliable.  I could definitely look outside, since it was VMC, seeing when I was level and when I wasn’t.  That would create a higher workload for me, which on a long flight like I was on, would lead to an increase in fatigue.  The solution?  The flight director!

    I turned the autopilot off, but I left the flight director up.  It wasn’t referencing the bank angle that the attitude indicator was showing since the KFC 150 goes off of the turn coordinator.  So, if I just followed the attitude indicator, I could just keep scanning the instruments and relieve a little bit of my workload.

    It actually worked really well.  By just following the flight director, I was able to stay on course and on altitude with only minor attitude adjustments whenever we hit turbulence.

    So, if you’re attitude indicator and autopilot decide to stop working on you, then bring up the flight director, push the same buttons you would if you were using the autopilot, and it works as a great backup.

  • Air Traffic Control Privatization

    ByHank Gibson

    There was a bill introduced in Congress recently to take control of Air Traffic Control away from the FAA and give it to a private, for profit, corporation.  The initial reaction of pilots is “Ahhh!  User fees!” which we are all adamantly opposed to.  There are a myriad of reasons why this is a bad idea (the “Flying” article makes a comparison to giving NASA to Richard Branson and Jeff Bezos) and we as pilots should be against it.

  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.
