tube, and feed the 1/16 alum tube D/T stop onto the line. String the second retainer hook
onto the D/T line, with tensioning band installed, but do not tie yet. Install the timer lanyard
over the stem of the timer to allow the end of the tripwire to become trapped under the
lanyard. Place the D/T line tensioning band on the retainer hook over the trip wire end, and
pull the D/T line tight until the band tensions the D/T line and pulls the stab down against the
incidence adjustment screw. Pinch the retainer hook and D/T line to capture the position, and
release band from the tripwire. Tie off the retainer hook and apply a drop of CA to secure the
knot-cutoff the excess D/T line.
Allow the stab to move to the 45 degree position and slide the 1/16 aluminum tube against
the end of the guide tube with the D/T line in light tension. Lightly crimp the forward end of
the stop tube to capture the location and pull the D/T line to clear the stop tube from being
against the guide tube and apply a drop of CA to the stop tube to secure onto the D/T line.
This limits the stab from over rotating during pop-up and becoming dislodged from the stab
platform.
Prop / noseblock assembly
Finish the noseblock assembly by installing the second thrust bearing into the aft end of the
5/32 OD tube. Secure the thrust bearings into the tube using cellulose cement or silicone
adhesive, as it may be desirable to remove these items in the future. Install two bead head
pins to act as posts for the rubber band retainers used to hold the noseblock against the
fuselage for flight.
Next, install the two scrap 3/32 retainer stops on either side of the fuselage. Pin prick the
tissue in the area these install to improve joint strength prior to bonding. In practice, the
dental band attaches against one retainer stop, stretches around the noseblock against the
pin heads and onto the opposite stop. Finish the noseblock with colored tissue or dust with
Design Master floral spray or colored dope if color is desired. Install prop shaft, Teflon thrust
washer, prop and bend prop shaft end to complete the noseblock assembly.
Install the two wing hold down pins. These are made from common toothpicks with the ends
cut off-in case replacements are needed. Start flying with the wing dowels in the center set of
holes. Do not glue the dowels in place. If you need to shift the wing for center of gravity
adjustment, you will need to reposition the pins to either the forward or aft hole locations.
Install the stabilizer as used for flight. Adjust the incidence screw in or out to set the stab
bottom to a horizontal position to start (parallel with the stab inset longerons).
Flight trimming
Check wings for washout in the outboard panels. It is suggested that the left wing have
slightly more washout than the right wing tip to help keep the right wing up during a climbing
right hand turn under power. The model should be trimmed to fly right-right (right hand power
climb transition to a right hand glide circle).
Install a lubricated rubber motor into the fuselage. This model has been flown very
successfully with 10-13 grams of rubber. Two loops of 3/16 rubber are provided in the kit,
and it is suggested to start with this for initial flights. Other combinations using 1/8 and 3/32
rubber can be experimented with once you have the model setup and trimmed.
