Check in flight by slackening the RH STARS cord that the LH turn can still be
compensated by weight shift, so that in the event of STARS cord failure, controlled
flight can be continued to a safe landing.
If the aircraft turns excessively left at high speed, apply a small amount ( maximum
20mm) of reflex on the LH wing tip battens 8&9 ( GTR wing) or 7&8 ( QuikR wing).
The ideal is to produce a steady LH turn at all speeds with the roll trim cord slack.
Once set up, it should be possible to apply a steady LH and RH turn at all trim
speeds, powers and loadings. Normally only fine adjustments are necessary through
the range, typ-1/4 turn.
Pilots who have previously had a Quik with the luff line pitch trimmer should resist
the temptation to adjust pitch trim with the roll trim knob! A placard above the wheel
(DP-086) states ROLL TRIM and L-R.
Sometimes if parked RH wing down in windy conditions, the roll trim knob can
become slackened off. Therefore
check roll trim before takeoff.
Emergency in the event of STARS cord failure.
In the event of a STARS cord failure, applying full fast trim and steering the
nosewheel towards the turn will reduce the turn bias. It is recommended that all
turns are made opposite to the hands-off turn. Much more push-out will be required
to land with full fast trim and remember to centre the nosewheel prior to landing.
Maintenance
On a daily inspection or particularly after rigging/derigging, check the STARS cords
are not frayed especially at the trim wheel, at the pulleys and at the connection to the
outboard washout rod post. Replace with genuine 3mm dyneema cord if there is any
sign of damage. Check the STARS cords runs are straight and not twisted around
either washout rod.
