[. . . ] TM A US DE MA IN Flite Models guarantees this kit to be free of defects in both materials and workmanship at the date of purchase. This warranty does not cover any component parts damaged by use or modification. In no case shall Top Flite's liability exceed the original cost of the purchased kit. Further, Top Flite reserves the right to change or modify this warranty without notice. [. . . ] Cut the shaped balsa Leading Edge to the correct length as shown on the plans and carefully bevel the ends. Center the leading edge vertically on the front edge of the ribs, then glue it to ribs W-2 through W-11. Make two Flap Servo Hatch Supports and two Aileron (or releasable drop tank) Servo Rails from two of the 1/4" x 3/8" spar cut-offs, then glue them to the notches in the ribs. If you don't plan on using flaps, fill the notches with scrap balsa (or you could install the rails anyway). Proceed to step 25 if you will be installing retractable landing gear. 21. Test fit a 1/2" x 3/4" x 6-3/4" grooved Landing Gear Rail into the notches in ribs W-4, W-5, and W-6. The fit should be snug and the groove should be facing away from the work surface. Be sure that the rail extends past W-4 approximately 3/4" as shown on the plans. Use 30-minute epoxy to glue the rail in position. With the bellcrank facing away from the plans, glue the aileron bellcrank plate into the slots in ribs W-7 and W-8. FOR RETRACT GEAR ONLY Hot Tip: The key to a durable landing gear mounting structure is building accuracy and good glue joints, not lots of epoxy. Please take your time, plan ahead, and work carefully during these steps. 25. Before using any glue or drilling any holes, test fit the plywood retract rails in the notches of ribs W-5 and W-6 together with your retracts. 22. Use 30-minute epoxy to glue the 1/2" x 3/4" x 1" maple Landing Gear Block to the top of the rail and the side of W-4F. 19. Test fit Tip Ribs W-12 and W-13 and the die-cut 1/8" plywood Tip Spar to the tip of the wing. Make sure W-13 is vertical and the jig tabs are contacting the work surface, then glue the assembly in position. 23. Draw a line 3/16" from W-4F on the landing gear rail. 26. Remove a section from ribs W-4 and W-3 so you may retract the landing gear, preferably with the wheel installed, into the wing. The shape or size of the pieces of wood you remove does not matter as long as it provides enough room to allow the wheel and landing gear to fully retract. These scraps will be glued back in place after this operation. 20. Locate the 5/8" x 1" x 7" balsa stick and make the Tip Leading Edge. Glue the tip leading edge in position. 24. Carefully drill a 3/16" hole at this mark in the middle of the groove all the way through the maple block with the drill perpendicular to the rail as shown in the photo. With the landing gear fully retracted, confirm that the strut and wheel go into the wing an acceptable amount. [. . . ] I will not fly my model aircraft in the presence of spectators until I become a qualified flier, unless assisted by an experienced helper. 3. I will perform my initial turn after takeoff away from the pit or spectator areas, and I will not thereafter fly over pit or spectator areas, unless beyond my control. 4. I will operate my model using only radio control frequencies currently allowed by the Federal Communications Commission. . . - 53 - CAUTION (THIS APPLIES TO ALL R/C AIRPLANES): If, while flying, you notice any unusual sounds, such as a low-pitched "buzz, " this may be an indication of control surface "flutter. " Because flutter can quickly destroy components of your airplane, any time you detect flutter you must immediately cut the throttle and land the airplane! [. . . ]
