MAIN WING AND CANARD MOUNTING MOUNTING THE MAIN WING
..... The main wing is permanently attached to the fuselage with flox and a series of BID tapes. .....Begin by leveling the fuselage both longitudinally and laterally. Use several pieces of scrap lumber and Bondo to firmly hold the fuselage in position. It is preferable at this time to allow sufficient room for the canard to slip up into position later. (See Mounting The Canard.) .....Locate WL30 on each side of the fuselage between the seatback bulkhead and the FS94 bulkhead. Refer to Page 8-2 for information detailing the location of the split line; this will assist in locating WL30. .....Remove the top portion of the fuselage shell between the seatback bulkhead and the FS94 bulkhead down to WL30. For convenience, allow 1" between your forward cut line and the aft face of the seatback bulkhead. .....If you have previously mounted the aileron system on the main wing, you will notice that the inboard phenolic bearings and linkages interfere with the FS94 bulkhead as you attempt to install and fit the main wing onto the fuselage. It will, therefore, be necessary to remove part of the FS94 bulkhead until the main wing is mounted by cutting a slot in the bulkhead. Later, after the main wing has been attached permanently, the slot can be filled in and the phenolic bearings laminated to it. .....Next, trial fit the main wing into position and begin trimming away the fuselage sides (downward) until the main wing fits into position. Check the lateral level of the main wing using a water level system consisting of some clear plastic tubing and water colored with food dye. Check that the centerline of the main wing is on BL00. ..... Small variations (0.1" max) in fit between the main wing and the fuselage sides are acceptable and can be filled with flox. Expect this fitting process to consume several hours of intermittent work. Don't forget to verify the fit with the main wing levelled longitudinally using the level board on it. .....Before mixing up the flox, recheck the fuselage and main wing level lines and blocks. It is very critical to your Q2's excellent flying qualities to have the proper incidences angles. .....Check the skew of the main wing by measuring the distance from each wing tip to the base of the vertical fin. The two measurements should be the same. If not, some shifting within the confines of the FS94/Seatback bulkhead fit should be accomplished to make the main wing as skew free as possible. .....Liberal quantities of flox should be placed wherever the main wing and fuselage will meet upon assembly. Verify good squeezeout of the flox upon assembly. Recheck all level lines and alignment. Permit the flox to cure prior to attaching the BID tapes shown. Two BID tapes are used everywhere, top and bottom)with a minimum width of 3 inches. .....Finally, the top section of the fuselage shell that was removed to enable the mounting of the main wing should be trimmed to fit, and bonded in place with liberal quantities of flox. Then,BID tapes are used, as shown, on the outside of the fuselage shell to attach the main wing cover to the main wing and fuselage. .....Also, any material removed to allow the aileron mechanism to clear should be replaced. Remember, this assembly is critical and should be accomplished with great care. Tie all major structure together with BID tapes and flox. |
