OC... ,
Re Query A, .. Nup no rudder cables outside the fuse ... Not sure of
the actual cable hook up back there as the 2 Batteries are mounted in the
tail and block easy view ...
B, .. Sorry can't remember the trim servo hook up
...but i will remove the cover plate and check back to u ..
C, .. Re the Tinnerman like disk .... i suspect home
fabbed up on the lathe .. Like Tim i bored out a hole about the similar size
for the tire valve access ....and used a rubber plug ( like used to
blank-off a wiring harness hole in say an auto firewall )
Sorry not more help ..

G'Day Tim,
Thx for the great Pic's and measurements ... are
really helpful ... Am i understanding u rite that with standard Gear
position ..(not wedged) ..u can hold ur Nose wheel off after touch down
like say a cessna/cherokee ..or ..?
Also i presume we all have the same 'molded stepped ' trailing edge on
the under skin of our Flaps and Ailerons ...is that what u have as well
Tim ..?
Thx
Graham

Hello 'OC' and Graham,
Attached are pictures of my horizontal stab. showing its dimensions. I
extended the cord of the elevator, but I forget how much. For me, I have
plenty of authority. The trailing edge is about 3/32" thick. The
trailing edge of my flaps and ailerons is 3/16" thick.
"OC" the pictures of my wheel pant are showing how I plugged my holes
with chrome caps from Home Depot.

Hello Graham,
Yes, with the standard gear position I can hold the nose wheel off after
touch down,with my enlarged elevator. If you measure your stock elevator
you will know how much I extended mine. 1 1/2" I think.
At main gear touch down I have to be sure not to relax stick pressure or
the nose gear will drop. If you can measure your cowl joggle to main
gear center line you can compare yours with several others that "OC" has
on a spread sheet. As I understand it, if you wedge your main gear
forward it reduces the speed of the nose drop which reduces the need for
a larger elevator to hold the nose
Mine also came that way but I filled them in with micro balloons to
create the 3/16 to 1/4" squared off trailing edge.
Good to hear from you,
Tim

Hello Graham, You wrote:
1) "Sorry not a big help on the rudder cable set up.."
No problem -- just curious about how Duane accomplished that. My solution
was a bell crank terminating the rudder cables with a push rod going to a
shortened rudder horn.
2) "will have to climb in back there and check its not wearing apart though"
I created a removable inspection panel on the lower left side of the
fuselage for access to the bell crank and associated connections.
3) "My TR1 came with shortened sticks" and ".... much heavier Stick
forces....."
Even with my extended pilot's control stick the ailerons are still very
heavy -- I noticed this same thing when I flew Rich's plane prior to buying
my kit. It is a nuisance flying my plane from the copilot's seat because one
has to reach down between their thighs with the tips of their fingers to
reach the very top of the stick grip.
4) "I built in a twist lock from a telescoping painting handle"
Clever solution.
5) "with say wing-leveler engaged working the lapboard while xcountry"
I recently replaced my Navaid autopilot controller with a Trio Avionics E Z
Pilot controller (kept the Navaid servo). This was a great leap forward in
capability.
