Mark Langford's KR2S Project

Columbia '98

revised July 26, 1998

Troy Petteway used his L-16 to introduce many of us to "low and slow" fun flying. That's Dana in the back seat.

At the Super Fil demo, Troy shows us how proper cleaning, surface preparation, and accurate mixing proportions result in an easily spread filler.

His example was his grandfather's old Formula One racer.

Friday night we went to Troy's house to see N100TP under reconstruction. Here, Mark Lougheed scopes out Troy's new "undersized" elevator, and increased horizontal stabilizer length. I wouldn't copy this until after the jury comes in...

Saturday morning started off in the parking lot. All it takes is a few KR builders and you've got yourself a productive meeting.

Frank's stock KR2 with homebrewed landing gear. The legs were Grumman Yankee legs split in half, with mounts similar to Diehl gear, but welded up with 1/8" 4130 steel. Troy has used this setup for years, and it's crash proven.

If you want some attention, be the ONLY KR at a KR Gathering.

This plane was originally built in '83, and sat in the Fayetteville hangar for 8 or 9 years under a tarp. I tried to buy it 5 years ago, but no way! I guess I should have come back and asked 4 years later. I wonder how much his hangar bill was after 9 years? Troy says it's a dream to fly.

Tailwheel fairing.

Heel brakes ala Petteway. Air in the lines is intentional to prevent vapor locking when they heat up. They are Hegar heel actuated master cylinders, ACS catalog number WBK01.1

Dana's force one hub. I can't believe I didn't get a picture of is very sharp red and black VW engine too.

Mark Lougheed shows off some of his associative CAD models of his new one seater design, along with a few thousand MathCAD formulas.

Troy flew Franks's KR around a few times just to get back in the KR mood.

This KR used the same method for hanging the front of the sling seat as the plans calls for on the rear of the sling seat.

Note door spring and pulley (behind pedal mounted to firewall). This returns the rudder pedals to keep them from flopping around.

Troy donates yet another part to Frank's KR cause. This is a carb intake snorkel that Troy swears will increase his power.

Steve Eberhart brought his immaculate wind tunnel specimens for all to drool over. Judging by the finish, he should have been a body man.

Jim Hill guards the beer cooler.

Troy and Frank swapped out the prop in an effort to pick up more RPM. It's a good thing, because one of the prop bolts was broken!

Mark Lougheed and Rich Parker inspect my N56ML version of the KR2S at Langford Manor.

They seem a little concerned with what they see.

Dr. Dean Collette's new "bombshell" fuselage construction method. The bent fuselage bottom is made up of 1/8" strips steamed and bent around an adjustable jig, then glued with Weldwood glue. The resulting bow is much stonger than a "U" glued up from three legs.
