I've just finished my 3rd Pizazz and did not have any problems with the wing saddle, bu if you have that much gap try this. Get yourself some 1/8 x 1/4 balsa, slide the wing into position and shim the wing with the strips. You know that this is a very active airplane so, check the aligment!!!!! modify the shims to make the wing align with the thrust line, if its not right it will fly up or down with any change in air speed. Cover the shims with some red paint and glue into place. Fuel proof this area with epoxy glue. On the first flight, it will get off the ground with ease, if it way out of trim pull back on the power so that you can adjust trims, this will save your plane. Ken....The "BALSA BANDIT"
