Appendix C, Modification M275, Roll Trimmer

Roll Trimmer for QuikR ( STARS equipped) and GTR flexwings.

General

Both the QuikR and GTR use the STARS system ( mod M252) which operates the
outer washout rods. In roll, the washout rods are operated asymmetrically to aid roll
response, and when slow pitch trim is selected, both washout rods are pulled
upwards, increasing pitch stability and avoiding tip stalling.
The roll trimmer ( mod. M275) works on the RH STARS cord, so that tensioning it
causes a RH turn by pulling up the RH washout rod, “tight for right, loose for left”.
Using the roll trim, any annoying hands-off turns can simply be trimmed out in flight.
See drawing YQE-0901 issue A for details.

Tuning

Since the roll trimmer operates on the RH wing only,  the wing is tuned to have a
MILD LH turn when the RH STARS cord is slack. By tightening the RH STARS cord,
a RH turn can be produced.   By varying the tension in the RH STARS cord,  the
wing can be trimmed  in flight to fly absolutely straight under all conditions of loading,
speed and power.
In general the QuikR and GTR tend to go left at high speed and power due to torque
and P effect.

Setting up

The wing tip adjusters need only to be adjusted symmetrically, i.e. both UP to reduce
trim speed and vice versa.
With no load on the roll trim cord, the roll trim wheel friction should be set by
adjusting the castle nut and split pin so that a force of 4 to 5kgf applied on the knob
is sufficient to move it.
If the aircraft is fully assembled and rigged for flight,
Set the pitch trim on fully fast ( i.e. slack trim motor cord) and the control frame
basebar held central in roll.
If the wing is off the trike, position the hang bracket central with the wing nose down
on a level surface.

Adjustment of the STARS cords.

There should be enough tension in the LH STARS cord to take out all the slack in
the outer washout rod cable ( part 17 in the drawing). Adjust by using the loop and
knot on the LH side of the keel pocket.
The RH STARS cord should be set up so that with 2 turns of cord wrapped on the
roll trim wheel, the tension is similar. The wheel should be set up so that clockwise
rotation = tighter cord = right roll.

Check Flight

Smooth conditions are adviseable.
Set trim for takeoff and ensure the roll trim is still set neutral ( 2 wraps on the wheel).
Take off as normal, correct any turn by weight shift.
Establish a mid range cruising speed ( typically 70

– 8o mph) and trim out in pitch.

Ensure the nosewheel is straight. It should be possible to produce a steady right
and left roll by using the trim wheel. Remember that a LH turn can only be produced
by slackening the RH cord, if the roll trim cord becomes slack and the aircraft is still
not turning left, land and adjust.
If more LH turn is needed, land and tighten the LH STARS cord.
