1. (Page 3-6) We are using a nylon cord with pulleys and weights to take the weight off the hot wire frame. One pulley is attached to the shop ceiling just above the cutting table and the other is attached to the ceiling about 6' away so the counter weight hangs out of the way. Hot wiring is much easier with the weight of the board removed.
2. (Page 5-1) It is impossible to make a correct wing and canard core as inferred in the plans when the templates on either side of the foam block are both paper-side out. One must be turned paper-side in. I have determined that templates on the left side of the block on Page 5-1 must be paper-side in, and the templates on the left side on Page 5-2 be paper-side out, but the builder should carefully determine this for himself.
3. (Page 5-1) With the width of the foam block given, it is not possible to place templates 2 and 3 nose-to-nose as shown. One will have to be below the other. Don't forget to flip template 2 (when on the left side of the block) so that the flat side is up, and the same for template 3 on the right side of the block.

1. In dress patterns for sewing, the reverse side of the pattern is shaded as well as the reverse side of the material. It quickly and easily clarifies instructions that could be otherwise confusing. We suggest QAC use this system in the Construction Plan Book. /Ed. Note: See #2 above/
From Steven MacLeod, #2200
1. (Page 8-2) Cut the ears off the fuselage jigging templates to allow installation of the horizontal tapes which join the shells.
2. (Page 4-1) Fabricate and trim the fuel tank prior to joining the shells since this greatly simplifies tank trimming operations.
3. (Page 4-2) Fabricate bulkheads and firewall from actual dimensions, not the full size templates since there may be some variation in size from templates to actual shells. /Ed. Note: The above comment was echoed by several QBA members./
From Bob McFarland, #2071
1. (Page 8-1) The most often asked question I get is: "Where do I find the fuselage trim lines?", which admittedly are hard to see, but all have found them when I explain they are the impression of scotch tape on the original plug, and that a sharp felt-tip can be used to follow them and make them visible.
2. (Page 9-9) There is no reason to make four aileron slot pieces as indicated in the plans - one set is all that is needed, because by the time they are used the rest of the wing is finished and the joint between inboard and outboard sections has been lost.
From Ronald Cross, #2397
1. (Page 5-2) When cutting out templates 12, 13 and 14, cut 4-A-B-C...I-B. You can then cut one side, down 4-A-B, around B-I, out B-A-4, and around the other side. The points 4 and F can be marked at each end of the core. The template can be removed and the cut 4-F performed with straight edge templates.
2. (Page 8-3) If you plan to make your Q2 trailerable, read Chapter 15 about installing the tail lug stiffeners. QAC should include Chapter 15 with the package!
3. (Page 11-5) Paragraph 2 says to join the wheel halves and then mount the tire. I have been told that the fit is too tight and the aluminum is too soft to do this. They recommend placing a wheel half through each side of the tire and bolting in place (don't pinch the tube). Also, check for burrs on the wheel halves before mounting.
4. (Page 6-1) After glassing the aileron top, put a long non-stick weight on the tail to prevent warping during cure.
5. (Page 3-2) Plans state that the jig table can be as short as 10' and as narrow as 2-1/2'. If the builder plans to jig the fuselage on the same table, it may be too short and too narrow; made mine 12' x 3'.
