Ну есть у человека возможность давать первогодкам бальзу на модели. Так почему из неё не строить? Бальза сейчас гораздо доступнее стала нежли хорошая сосновая рейка.
А в чём проблема?
Две пластинки бальзы на группу, это не те деньги, чтобы рассуждать на эту тему.
Две тысячи рублей на ребёнка за целый учебный год, это может позволить себе каждый родитель (222 рубля в месяц).
Этих денег хватает на всё: бальза, ватман для черчения, ручки геливые, карандаши, ластики, лезвия для ножей, скотч, цветные маркеры, пластилин, дипломы, сосновые рейки, углепластиковые хлыстики, смола, циакрин, клей ПВА, плёнка тонкая термоклеевая, плёнка цветная.
Этого хватит, чтобы построить три модели.
Не надо в жизни всё усложнять.
