Re: Roll trim and eliminating slop (No not for the hogs!)

Larry Severson

There is a simpler method. Separate the two sides
of the elevator control. Put in 2 push rods from
the stick. Place a turnbuckle on one of the push
rods. It will allow you to change the incidence
of the related elevator side giving easy, complete roll control.

Hi Bruce,

Thanks for the enthusiastic and complete
description of your mod. I am still at a stage
where I can do the same mod (before it requires
mod-ing). I am still having a hard time getting
my head around it. I am sort of visual, so a
couple of pictures posted on the site would make
this much more clear to me. Or if you can do a
video (Youtube?) maybe taken with your phone
(because it can go where a camera can't). This
would show how the whole assembly looks and
works. When combined with personal your
commentary, I think it would be a best seller! Much appreciated.

I test flew my newest modification on my TriQ
200 today! In the past 2+ weeks I cut out a
hole in the top of the bottom fuel tank so I
could run push/pull tubes from the stick
directly to the elevator actuator arms. The
hole wasn't big but the tubes needed a valley
to run in.I used 2 turnbuckles with left and
right hand treads from McMaster Carr. I lock
one turnbuckle down with jamb nuts and leave
the other free to turn but which has a limit to
keep it from screwing out of the rod end
bearings. My old system used a bungee strap to
pull the ailerons over to the light side of the
Q. I could see that they added a bit of stick
pressure and also looked like they might add
some drag esp when I am solo and very left wing
heavy (the ailerons were quite remarkably
deployed to offset).The flight today was a much
improved TriQ! I may have increased my cruise
speed by about 6 to 8 mph. The jury is still
out on that as I don't remember exactly what
the former cruise was. Only that the old
indicated was somewhere between 145 to 147 and
I don't remember what altitude those number
come from (2300 to 4000 msl maybe). Today the
cruise was mostly at 154 mph and that was at
4000' msl. The altimeter was 3007 and temp was
around 45 degrees. My airspeed is off about 8
to 10 mph slow at cruise so I figure true
airspeed was around 174. I could be wrong but
at least I feel I had an increase in
airspeed.The stick pressures were almost
surreal as I trimmed the elevator back and
forth. Just a little trim and it rolled quite
nicely and easily. The handling is much better
than adjusting the bungee trim and loading up
the system. In the past I worked quite
extensively on the sparrow strainers and they
are neutral for cruise without the old spring
pitch trim. It has been removed and the pitch
is lite so the roll trim is not loaded up with
up or down pressures on the old spring
system.All it takes to roll the airplane left
or right is one finger on the trim wheel!In the
past I have had a bit of slop in the elevator
system. When I would do an aileron roll the
plane would be out of trim after the roll. So I
attacked the elevator torque tubes and actually
used 4 large Cherry max pop rivets to help the
-3 bolts that held them in place (I know it's
going to be really tuff to get them off in the
future). Now they are rock solid! I also (with
the help of Terry Crouch's article/interview
with the late Dave Richardson and his advice
and also Paul Fisher's input) did the mod to
the inboard end of the elevators. The mod makes
a bit of a rib and also surrounds the tube in
the elevator with BID and also Flox. It also
keeps any fuel from getting in through the bolt
hole access in the top and bottom of the
inboard end of the elevator skins compromising
the bond with the tube and the surrounding
foam. The mod can now drive the entire elevator
on the inboard end if needed. Just a bond with
the foam and micro was of concern for me.After
the test flight I need to adjust the elevators
at the torque tubes because the elevators don't
come down> __________________________________________________________
