Well John, that does make sense. 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.
Thanks
Bob

With a steel leg terminating at the midpoint of the gear leg
socket, one has effectively constructed a shear at the
weakest point of the socket.
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.

Bob, I'm in the process of overhauling the brake system on a Just Aircraft
Highlander with Matco internal caliper brakes. 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.
