Sling 4 Kitplane - Around The World Flight

Most builders who are considering various Kitplane capabilities usually are not thinking about flying around the world.  Kitplane builders many times bias their build selection to fit their regional flying environment, while others do consider extended cross-country operations.  Maybe you want 4 seats with solid cross-country cruise speeds, so a RV-10 may come to mind.  If you wanted mountainous backcountry flying abilities, you might take a look at the Just Aircraft Highlander.  Frequently, the selection of a Kitplane is dictated by the primary flying mission the builder is looking to target.

If you really wanted to, could a modern day Kitplane be trusted to fly around the world?  How about the Epic LT?  Sure it could fly around the world, but that is an executive class turbine powered beauty!  For this question of flying a Kitplane around the world, I would like to present a recently developed example of sleek efficiency.  The aircraft detailed below is a 4 seat low-wing design, built primarily from aluminum, with a turbocharged Rotax 914 forward of the firewall.  This same aircraft has just completed a trip around the world....yes indeed, how is that for capability!  As you will see, The Airplane Factory out of Eikenhof, South Africa has definitely demonstrated the potential for ignoring limiting beliefs.   Let's take a look at this smart new design that has opened many eyes in the Kitplane world - I introduce you to the Sling 4!

Take a look at this great video covering the Sling 4 aircraft launch at Tedderfield Airfield South Africa -

Here is a final video as the Sling 4 arrives back in South Africa after completion of a round the world trip.  The Airplane Factory set a very ambitious goal, to fly their new Sling 4 aircraft around the world, and I feel their accomplishment will be rewarded with great respect -  CONGRATULATIONS on a job well done!

Kitplane Engines - Lycoming IO-233

The next Kitplane engine highlighted here is the brand new Lycoming IO-233 / O-233 built specifically for the LSA and Kitplane market.  The IO-233 is a four cylinder, air-cooled, horizontally-opposed piston aircraft engine that produces between 100 hp (2400 RPM) and 116 hp (2800 RPM).  This engine is a modernized version of the previous Lycoming O-235 with engineered weight reduction and modern engine ignition technology.  The new design features include the incorporation of throttle body fuel injection with an optimized air induction system and dual electronic ignition, or optionally a carburetor in place of the throttle body injector to save further cost and weight.  There is substantial overall weight reductions and improvements in engine size to target the IO-233-LSA for today's Light Sport Aircraft market. The engine is also approved for 2,400 hour time between overhaul (TBO) intervals giving it one of the longest Light Sport Engine TBOs in the market today.  To offer pilots fuel options, this engine is approved for the use of 100LL or 93 AKI automotive (MOGAS) based fuels that conform to Lycoming specifications.

The initial standard version of the Lycoming 233 series engine is carbureted. Lycoming continues to incorporate input from pilots and manufacturers all over the world, which will result in both carbureted and injected configurations of the product.  Here is a very sharp looking Kitfox Super Sport with a Lycoming O-233 (carbureted version) installed -

Kitplane Engines - Rotax 912 / 914 Series

Today I will cover some of the current engines used by various Kitplane companies and builders. There are both air-cooled and liquid-cooled powerplant options, and I will take a look at a few of the common choices available. The engine choices I will document today are in the 90 hp to 130 hp range which fits with the horsepower requirements for many Kitplanes. For Kitplane builders, one of the criteria for engine selection is the type of fuel used and I will point out those details. I wanted today's blog post set up as a Kitplane engine reference guide, so you will see many informational links throughout this posting.

The first engine I will cover here is the well known Rotax 912 and 914 series. The Rotax 912 / 914 series are 4-cylinder, 4-stroke liquid/air cooled engines with opposed cylinders. The 914 series is similar to the 912 but has turbocharging added for better performance at higher altitudes. Both the 912 and 914 offer a 2000 hour TBO (Time Before Overhaul) and over 15,000 units have been sold worldwide. There is wide range acceptance for the Rotax engines throughout the Kitplane market and this engine has become a very popular choice. This series of Rotax engines are approved for the use with Ethanol E10, MOGAS, and AVGAS fuels.

Rotax 912 and 914 (Turbocharged) series basic details;

4-stroke, 4 cylinder horizontally opposed, dual spark ignition engine, one central camshaft, pushrods, OHV -

• Liquid cooled cylinder heads, ram air-cooled cylinders
• Dry sump forced lubrication
• Heavy duty electric starter and starter relay
• Dual breakerless, capacitor discharge ignition
• Rectifier/regulator
• Electronic dual ignition
• Integrated reduction gearbox (i=2.43) with slipper clutch
• Integrated AC generator
• Mechanical (engine driven) fuel pump
• R.F.I. suppression
• 2 carburetors

Now I want to show you a few videos that showcase the Rotax 912 series engine;

Flying the Rans S-7S Courier

Over the weekend I had the great opportunity to take a trip in my local flying area in a S-7S Courier.  I have never flown in any of the Rans high wing aircraft and I have to say this was definitely a treat.  The S-7S I flew had just been fully upgraded to the latest model specs and is very similar to the new 2012 model Rans S-7S kit.  You can buy the S-7LS version as a fully built factory LSA (Light Sport Aircraft) or you can order the S-7S kit and build it yourself - so either option is available.

I would say a person could build out a very nice S-7S for around $70,000 and that is a completely built, painted, and ready to fly aircraft.  I spent some time looking over the S-7S in detail and I was very impressed by the overall kit design and components used.  All the hardware and component pieces that are a part of the kit look exceptional in quality and appearance (and that is coming from a 20 + year A&P).  I noticed details like windshield fitment and nose cowling alignment were very clean - no gaps or odd fitting areas.  Even fine component and assembly hardware detailing is found throughout the tandem seat interior (pilot front / passenger aft).  The Rans S-7S is just a very complete kit with sharp attention to the details - it was not hard to find the quality in this beautiful Kitplane!

The first thing I noticed while getting ready to fly the S-7S was good seat positioning, interior room for a tandem, and overall visibility.  Once you rollout for takeoff and get airborne the visibility is just awesome!  Enjoying some low and slow sightseeing or looking for traffic in the pattern is done with ease in the S-7S - the view from both front and aft seating positions is perfect.  Also, you can leave one of the doors latched full up and open during flight without a problem ( at moderate speeds and below).

The S-7S I flew was equipped with the typical 100 hp Rotax 912 series engine we see in many Kitplanes these days.  The Rotax 912 works out very well in the S-7S Courier and provides cruise speed around 110 mph.  With Rotax 912 power, the S-7S leaves the ground early on takeoff and short field operations are at your service.  Take a look at the S-7S full specs for additional details;

Rans S-7S Factory Specs ----->  http://www.rans.com/build-it-yourself-kits/152


Flying the S-7S is a delight with flight control stick forces that are weighted properly and never feel overly sensitive.  The S-7S is easy to fly with cable operated Aero-Servo Differential ailerons and rudder (Rans uses ball bearing aircraft cable pulleys for very smooth control feel).  The elevator is operated by push-pull tubes and the aircraft kit comes standard with electric elevator trim.  The S-7S was a treat to fly and I think this is an excellent aircraft choice for those looking into high-wing Kitplane options.  Take a look at this recent Rans video for an overview of the current 2012 S-7LS Courier (Light Sport factory built version);

Zenith Aircraft

Today I want to showcase one of my favorite Kitplane companies - Zenith Aircraft.  I do love many aircraft designs from the wide range of Kitplane companies, but I really appreciate what Zenith Aircraft brings to the market.  This August I traveled north to the Zenith Aircraft factory in Mexico, Missouri to see the great aircraft they are building.  What I found at the Zenith Aircraft factory was an exceptional team with great hospitality.  Everyone I talked with on a tour of their factory was very helpful as I asked questions, and I could feel their passion for the products they build!  I was very impressed to say the least.....top tier Kitplane company in my book!

Zenith offers several different aircraft for the Kitplane builder and they have some recent design upgrades.  I want to showcase two Zenith Aircraft that have had recent design and features upgrades.....so let's take a look;





CH 750 (two seat)

The CH 750 is a STOL (Short Take Off and Landing) design that is extremely capable for all kinds of flying missions.  Now I want you to watch a really good video that highlights the CH 750 kit components and how the build process works.....check it out;

For those with any mechanical aptitude or an interest in working with your hands (and your brain....LOL!) can you see how this could get addictive?!?  This is a GOOD addiction!

CH 650 B (two seat)

To see what these Kitplanes look like before they are packed and shipped to builders, our next video details a CH 650 B as kit components;

I hope the videos presented here gave you a good overview of the sharp Kitplanes from Zenith Aircraft!  For additional in depth details about the excellent Zenith Aircraft company check out their site -  www.zenithair.com

Kitplane Capabilities

Kitplanes can be selected and built for a very wide variety of missions to include;

*  Local Area Flying

*  Cross Country Flying

*  Back Country Flying

*  Aerobatics

*  Floatplane Operations

I have listed some of the typical uses of those who build and fly these very capable aircraft.  Now let's watch a video of some great Back Country fun in a Kitfox Super Sport!

Sign me up for Back Country Kitplane flying!!!

So what is a KITPLANE?

I decided to start a blog to highlight one of my passions in life - KITPLANES!!!  In the months ahead, I will introduce you to an amazing category of aircraft that are available to the flying public....and these aircraft are very special!  Kitplanes are planes that can be built from prefabricated kits or scratch built from blueprints and assembly manuals.  Kitplane aircraft are available from a wide range of general aviation companies throughout the world.  These companies produce kits that range from small single seat planes to even large aircraft kits that could carry 7 passengers or more.

Let's take a look at several examples of current Kitplanes in the market;

The Sonex OneX (single seat)

Zenith CH 650 B (two seat)

The Kitfox Super Sport (two seat)

Vans RV-10 (four seat)

Epic LT (up to 7 seat)

As you can see, there is an extensive range of aircraft available in the Kitplane market.  These aircraft are regulated by the Federal Aviation Administration through the Experimental or Light Sport Aircraft categories.

For an in depth look at the Experimental Aircraft category take a look at the Experimental Aircraft Association site - http://www.eaa.org

For an in depth look at the Light Sport Aircraft category take a look at this Sport Pilot site - http://www.sportpilot.org/learn/aircraft_index.html
