How much does the average KR cost to build?

 

The average cost for a well equipped KR with an auto conversion engine is around $35k depending on instruments and avionics.   Our complete airframe kit with a fast build fuselage, prefabricated components and many of our most popular options is under $17.5k.

 

  

How fast is the KR?

 

There are many factors that affect the performance characteristics of this aircraft.  If you build a clean, light aircraft with a 100+ horsepower engine you can expect a top speed of up to 200mph with a cruise between 170 to 180mph. 

 

 

How long does it take to build a KR?

 

One of the largest advantages of the KR, over other aircraft is its easy building techniques.  Utilizing wood, foam and fiberglass, the KR does not require any previous experience or special skills.

If you were to build fairly consistently, utilizing all our prefabricated components, you could expect to have an airframe ready for Interior, Instruments, Engine and Paint, in less than a year.  Utilizing our fast build fuselage and prefabricated components can save you over 850 hours.

Is there a KR builder's network?

 

Mailing List:

There are many builders who subscribe to Mark Langfords KR Net Mailing List.  This is a great place to engage other KR builders and pilots, for advice, help, guidance and motivation.  There is a searchable archive going back to 1994.

 

Message Forum:

There is a message forum available specifically for the KR Builder Community.  This forum is designed to allow you to easily find the information you need to help you in your project.  If you cant find what you are looking for, utilizing the robust searching features then you can engage other builders and share your ideas.  There is also a Complimentary KR Classified, to allow KR builders to buy, sell and trade KR related items.

 

Builders Log:

This is a FREE service provided by nV Aero to allow builders to document their project and share their journey with fellow builders.  It is part of the KR Builders Community.

 

Newsletter:

You can order 27 years of the original KR newsletter from Larry Capps.  Also, there are several online newsletters available on the KR Net.

Are there builders near me?

 

The KR design is nearly 40 years old with flying aircraft in several countries.  Check the mailing list and forums mentioned above or your local EAA chapter for a builder near you.  Chances are you will not have to look too far, to find a fellow KR builder.

 

 

What are the advantages of the KR over other similar Aircraft?

 

  • Easy to build minimal skills required.

  • Common tools that may already be in your garage.  No expensive fixtures and saws.

  • Fast build time, so you are flying sooner.

  • Highly competitive pricing, so you can achieve this dream on a reasonable budget.

  • Economical to fly and maintain.

  • Strong Builders Community.

  • Builders Support via Toll Free Phone, Fax, Email and Forums.

What skills do I need to build a KR?

 

Like with any project, motivation, patience and desire will ensure you persevere.  The KR is a very easy aircraft to build, not requiring any special tools or previous skills.  While having previous experience will speed up the construction of your aircraft, with our prefabricated components you will be able to keep your project on track.

 

A keen attention to detail and the ability to follow written instructions will certainly save you a lot of time and frustration.  While fiberglass is very forgiving, there are a few areas where not following the directions could set you back in your project.  It is suggested that you read ahead to get a better understanding of the overall process.

 

The basic skills for working with fiberglass can be learned by experimenting with some sample pieces, taking a local workshop, a good book on Experimental Aviation Fiberglass, the builders community listed above, the EAA or all of the above.  In the end, you will find your groove, the techniques that work best for you.

 

The most important thing is to enjoy the process, learn as much as you can and have fun!

 

 

How many people does it take to build a KR?

 

The entire aircraft can be built by 1 person.  There are no functions or procedures that really require a 2nd person, although sharing the journey can make it more fun.  It would be beneficial to have some help when mounting your wings and getting your aircraft on its gear for the first time but with some creativity, this can be accomplished alone as well.

 

 

Can a low time pilot fly a KR?

 

The short answer is Yes.  For those intending on building the taildragger version, we highly recommend you get some dual instruction time in a taildragger before flying yours for the first time.  Other than that, the KR has great flight characteristics and is a wonderful

Taildragger vs. Tri-Gear which is better?

 

The age old debate!  It comes down to personal preference and comfort levels.  The taildragger is a little bit cheaper to build and has a slight performance advantage over the tri-gear.  The tri-gear is easier to taxi and a more natural transition from most certified aircraft.  Many people like the appearance of the taildragger, with sleeker lines.  In the end it is more of a question of, which is better for you?

 

 

Is retractable gear available?

 

Although the original KRs offered a partial retractable gear, we are not currently offering this as an option.  However, we are currently prototyping a full retractable gear that is much lighter than the original design and it will fully retract into the stub wings.  We intend on making this a retrofitable kit, so anyone that has already built their aircraft can still install this landing gear.

 

Can I use an auto conversion engine?

Yes and most of the performance specifications documented by the designers are utilizing a Volkswagen engine.  There are Pros and Cons to using a converted VW or Corvair engine versus a certified Continental O-200.  We recommend that you research these options very carefully and make the decision that meets your individual needs and comfort levels.
