If you want the plane to fly with a minimum of problems you will need to do the following:

1. Make a saddle to fit the Avistar wing to keep the wing from shifting in flight.

2. Secure the saddle to the Skylark.

3. Mount the wing and check your incidence (shim as needed ). MOST trainers have a 0 degree on the main wing and a 0 degree incidence on the horizontal stab,

If your incidence are off you will have "an interesting" flight.
