I live just about 50 airmiles South of your unintended landing at the falls. I think I will install them as they are. I fly off a 2000' grass strip and PLAN on any off field landings. Has anyone moved the battery to the nose section of the plane? I know that is a long way to run the positive cable but It sure would help with the CG.

I haven't paid that much attention to the old solid steel legs. Did not realize they were designed short. Before I would relocate the battery from the CG to the nose I would test fly the airplane. Now that is what I would do if I had an itch to put a heavy battery way up there. Heck, we have had folks haul lead in the nose. Nose down pitch at cruise and full power is the biggest annoyance of a MKIII. Normally, they do not have a CG problem. Adverse pitch down is caused by the high thrust line of the pusher configuration. Can be dealt with by forced trim and aileron adjustment. john h mkIII Titus, Alabama -----Original Message----- From: owner-kolb-list-server@matronics.com [mailto:owner-kolb-list-server@matronics.com] On Behalf Of pipercolt Sent: Friday, April 10, 2015 7:02 PM Subject: Kolb-List: Re: MK 111 rebuild Well John, that does make sense.

I've not seen it mentioned in the manual but make sure the calipers are mounted such that the airflow carries the brake dust away from the sliders on the caliper. For the internal calipers that's AFT of the axle. Also, the Highlander was experiencing severe pad wear. Worn out in 30 hours. My theory is that the Nylaflow tubing was installed so that it had to have an "S" bend that caused the tubing to act like a spring and keep the fixed pad in constant contact with the disk. The fix, again my theory, is to put a 90 degree steet ell into the caliper pointing toward the center of the aircraft and a 45 degree 1/8 NPT to 1/4 compression fitting (Matco has them: http://www.matcomfg.com/BRASSELBOW45DEGR18NPT14COMPRESSIONWITHINSERT-idv-3584-35.html so that the brake line follows the gear leg all the way to the caliper with minimal bending. Like I said, that's the theory so use at your own discretion.
