Building Extra Sports 30

*Before assembling this Extra Sports 30, please read the instruction manual throughly.

MAIN WING (step #1&2)

Mark the hinges in the middle as shown. Insert hinges up to the line marked to hinge slots in the wing and use CA or superglue. After the glue sets, fit test the aileron for perfect fit before glueing. If OK, then glue and align properly. Put more glue inside the linkage hole for best aileron control. The same method also can be applied to elevator and rudder installation.





Before glueing the wing halves together, remove the excess covering from the inner wing cross section. Next screw in the aileron plastic horn bracket to the aileron wire. Remember to apply more epoxy into wing tube to prevent from coming off during flight. G-clamp the wing halves together and leave overnight. I used slow set epoxy here for stronger bond. Any small gaps can be filled with epoxy later.

While waiting for the wing to set, skip to Step #5.

MAIN LANDING GEAR (step #5)

Remove and peel-off the covering. Screw- in the landing gear and apply threadlocker. Next, install the wheels with screws,washers and nuts supplied. Remember to threadlock the wheels lock nut. I don't used the wheel pants because due to our grass flying field.

Landing gear secured and threadlocked.
