hi friends with your help i have made a sweptback foam handlaunch glider of 4mm thickness and sanded it to desired shape and  i gave knowingly tailplane positive incidence due to uneven surface in bamboo fuselage and this resulted in adding more modelling clay to balance the model so totally model heavy yet i have learned a lesson from this project and thanks very much friends

now i have given a notch at the nose for catapult launching but wings are of foam and it breaks immediately when launched with fullforce and so i decided to provide reinforcement to foamwings
and i am going to provide droomstick sticks for housecleaning purpose to use.will it work and how should it be done?please help this beginner..
