    hi friends i have made a 8inch wingspan biofoam(4mm)catapult launch glider.
    materials:
    1.biofoam of 4mm thick
    2.bamboo for fuselage
    3.balsawood for fin
    problem:
    1.foam of wing bends when launched with full stretch by catapult
    solution:
    1.given a reinforcement in the wing with 0.2cm thick woodstick used for home-cleaning.

    question:
    1.shall i need to give reinforcement for tailplane?
    2.what are the materials can be used for reinforcement?
    3.how should i groove in wing for placing the stick for reinforcement accurately?
    thanks
