HOG.BIPE DUAL SERVO SET.UPr.ri

.1in,,

Using the dual servo set-up you will not complete steps 39A or 44B. On step44C sheet the top of the wing like you did the bottom.

35 c. Using pieces of the 1/16" x 1/4" balsa str ip, cut and glue capstr ips onthe bottom of the wing as indicated on the plan, but at the servo bay glue thecapstrips flush with the inside ol the rib, as shown on the small plan sheet.NOTE: that the capstr ips at the l-strut mount (P-3) are cut from 1116" x 112"balsa strio.

39 a. Using the small plan sheet as a guide, cut four hatch rails from the spe-cial-cut 1/4" x112" x 16" basswood st ick provided in the kit . Glue the hatchrails flush with the bottom edge of the W-2 wing rib in each panel. The hatchrails provide a seat lor the aileron hatch and a llat surface lor attaching thecovering material. You will have to sand a little off the fore and aft ends ofthe rail to match the curve of the wing rib. Sand an equal amount off the seatsurface of the rail to keep the hatch flush with the wing.

39 b. Lay one laser-cut 1/16" plywood hatch on the hatch rai ls and dri l l four1/16" holes in the rai ls using the holes in the hatch as a guide.

39 c. Cut four 3/8" x 3/8" x 3/4" pieces off the 3/8" x 3/8" x 4" basswood touse as ai leron servo mounts.

39 d. Mark the location of the servo mountino screws and drill four 1/1 6" oilotholes {or the screws.

39 e. Mount the servo to the basswood mounts using the grommets, eyeletsand screws included with your radio.

39 f. With the servo electronically centered position the servo with mountson the laser-cut hatch cover and center the servo arm in the slot. Glue theservo mounts io the hatch cover. When the glue has cured remove the servofrom the mounts and apply a second coat of glue to the mount and hatchcover. Be careful to make a lett and a right SEf\o hatch assembfy.

39 g. Mount one hatch/servo assembly in the wing, using four #2 x 3/8"sheet metal screws. Using the small plan sheet as a guide make an a aileronpushrod from a 4-40 x 8" threaded rod, a 4-4O{solder clevis €nd"a 4-40threaded clevis. The actual length of the pushrod may way slightly based onthe shape and position of the aileron servo.

39 h. Connect the solder clevis end of the pushrod to the servo arm. Keepingthe pushrod parallel to the ribs mark the position of the pushrod on theaileron. The small nylon control horns, one right and one left are used on thelef i and r ight ai lerons.

39 i. Center the aileron servo electronically. Hook up the small nylon controlhorn to the pushrod and center the upright portion ol the horn on the aileronat the mark. Vertically line up the clevis attachment holes with the leadingedge oi the aileron. Mark the positions ot the holes in the control horn anddrill a 5/64" hole at each mark. Reinforce the control horn area by soakingthe wood around the holes with Thin CA. This will help keep the control hornfrom crushing the balsa when the control horn is installed. When the gluehas cured redri l l the holes. Using the small plan sheet as a guide, mount theInterconnect horn the same way you did the small control horn.

Repeat for the other wing panel.
