it's FIRST FLIGHT !!!!!
This web site is designed to allow you to view the building process of my KR-2S experimental aircraft. All information provided herein is the opinion of the builder and should be viewed as such. This web site is not in any way related to Rand-Robinson Engineering. This aircraft is 100% plans built and any modifications to the original drawings were made at the discretion of the builder.

Mark's e-mail address:
My project began March 21, 1998 and made it's FIRST FLIGHT on MARCH 20, 2005 almost seven years to the day.  She is sporting a Corvair engine based on the conversion procedures of William Wynne. The engine mount is a design of William Wynne and Mark Langford. The tri-gear she is sitting on is manufactured by Dan Diehl. The canopy is a Dragonfly canopy. The prop is made by Sensenich Propeller Co.
  My KR-2S is based at Zephyrhills Airport (KZPH) in Zephyrhills, Florida.  
The photo above was taken 7/23/2006 at the KR/Oshkosh Mini Gathering held at my hangar the day prior to AirVenture. This photo was taken by Mark Langford as Bob Glidden piloted Langford's KR-2S. This was also Bob Glidden's first flight in a KR and he was amazed at the performance and ease of handling of the KR.

As seen in the photo below, for the 2007 KR Mini Gathering at my hangar, we had a total of six KR's show up. They included from left to right: Rob Schmitt (KR-2), Joe Horton (KR-2S), Mark Langford (KR-2S), Bill Clapp (KR-2S), Mark Jones (KR-2S) and Pete Brautigam (KR-2S). We flew as a group of five (Pete was unable to fly there) to AirVenture 2007 on Sunday the 22nd. When we arrived, Jack Daugherty (KR-2) was already there waiting on us which made for a total of six KR's at Airventure 2007.

The photo below was taken at Oshkosh AirVenture 2007 just after we arrived by Cerdic Gould. Left to right, Mark Jones, Joe Horton (kneeling), Bill Clapp and Mark Langford. Rob Schmitt was parked in homebuilt camping so he did not make this photo and Jack Daugherty was not there to be in the photo. The KR's in the photo, front to rear are: Mark Langford's, Mark Jones', Jack Daugherty's and Joe Horton's. Bill Clapp's was parked in a different row.

The photo below was taken by William Wynne as I departed Oshkosh 2007.

This photo shows my plane in Mar Hyde Ultimate 2K primer before I painted it. I flew N886MJ about 70 hours before she got her final paint job. The photo was taken at Hartford (HXF) Airport in Wisconsin.

The photo below was taken over Mt Vernon, Illinois (MVN) from Mark Langford's KR-2S by Ron Willett on 9-10-2005 at the KR Gathering. Flight time when this photo was taken is right at 50 hours.

    The following three photos were also taken from Mark Langford's KR-2S over Mount Vernon, Illinois by Ron Willett on 9-10-2005 at the KR Gathering.

    The following two photos were taken by Joe Weber out of his KR-2 during my third flight over Hartford, WI on 3-28-2005. I really like the first one with the reflection on the canopy which reads experimental. That sort of tells it all.

    The following three photos were taken at Waupaca, WI on 8-20-2006. These photos compare the size of a KR-2S to a DC-3 named "PUFF".
