Hi Bud,
Reviewing my emails I noticed your thorough input below to my trim question.
I posted recently, some time later, my conclusions, which aerodynamically I
will vouch for, but, it is contrary to what you recommended. The manual omi
ts to tell you the orientation of the rivet pattern, which has been the root
of my dilemma. My components conflict because of the rivet head, which is a
real irritation. I often build too fine tolerances, which is probably a com
mon perfectionist trait, but it commonly creates problems, like this one. I
am chasing around trying to get all the pitch circuit sorted, with the top o
n and off trying to get the counterweight throw sorted too, so that the tail
plane hits the bump stops before physical stops. As I did it years ago, I am
relearning everything including soldering and fine wire connections for the
RC Allen servo and position gauge. I would like to know what form of connec
tor you recommend on the fine wires of the poaition indicator? I could solde
r on a D-Sub fitting but would prefer a Fast-On crimp but they dont seem to s
uit below a #22 AWG wire. I also have to get the indicator's connector throu
gh the panel hole, because as i recall it is slid into the hole and rests in
place with a surrounding flange. I am in Tokyo, so cant check at the moment
, but the implication is that my connector needs to go through the hole, and
the wires are not that long out if the position indicator to not get it rig
ht the first, or at a pinch, the second time.
Seems my cranked control sticks with my Tosten grips are going to give me gr
ief too, as they sit ontop if the stick, through a 1" insert, so the sticks h
ave been cut down as much as possible but still conflict with my panel. I mi
ght have to cut and weld in an insert in the middle portion of the stick. It
currently doesnt seem to come back far enough at full aft stick, as its onl
y mid thigh. I reckon it should come back till my left elbow is against the s
eat back would be a good geometry test, so I need to get it back more. I hav
e a fence arrangement around the bottom of my sticks, to attach a leather bo
ot, and stop FOD jamming the controls, but it now makes iy very awkward for m
e to get in there to try and lengthen the link rod, to crank back the entire
range. So, still a work in progress, but I was told to work from the back f
orward, which is why I'm messing around with trim units. So Bud, if you've g
ot any tips about small wire connectors, i'll soak it up with thanks.
Regards
Tony Renshaw

push rod, should not contact the TS 03 bell crank long arm side where the t
rim clevises attach at full up stab (I use 13 degrees full up). The clevis f
rom the motor to the clevis on the TS03 butt against one another on the #8 r
od attaching them. If you look with the stabs all done, trim tabs on, and f
ully extended trim motor, look hard at the TS05 trim rod and it normally jus
t contacts the clevis. Simply take it apart,(it is an airplane so if you ha
ven't taken it apart and put it together 5 times, you are doing it wrong.) c
ut 1/16 inch from each clevis and reassemble and test. 1/8 inch off each is
the most I have done. At this time check the TS05 trim push rod does not r
ub against the slot in the bulkhead it passes through. This is very hard to
do with the top on.

This has never happened to me. Easy fix, a drop of Loctite and tighten up w
as all it took. I use torque seal paint on all my bolts but never put it on
my nylock / check nut on the drag / dampener bolt as I never thought this p
art would cause trouble... So a word to the wise, make this part of your fi
nal assembly check, and put a bit of torque seal paint on your nuts on this p
art also.

et to a nut easily. (Yes, it takes longer but we have not had good luck wit
h gluing a nut on over time.) We also use a #6 Allen head screw to hold the t
rim motor on since it is easier to put an Allen screw driver ball head on it
than a wrench should the trim motor need to be changed some time in the way
distant future. (I've never had a Mac Servo fail, but I have a D sub on i
t anyway, just in case.)
