Tech One has constantly been striving to achieve lighter weight and rigidity in their planes and these new depron foam planes shows off their latest ingenuity.
This Tech One Extra 330 uses HCF technology effectively reducing the weight of the entire plane. The flying weight of the planes is merely 120-140 grams with the recommended battery type. This extraordinary feat is achieved by using laser machinery to hollow carve the depron foam. The motor mount, horns and other spare parts are all constructed of carbon fiber to keep things light and strong. They use a clever X interchange design to reinforce the ailerons in order to improve the torsional strength while not adding weight. To ensure a strong adhesive bond between the joints of film and the foam, Tech One applied their advanced filming technology which leaves no residual adhesive inside the carved hollow areas of the fuselage and stabilizers. An ultra thin polyester film covers this beautiful construction and is printed with amazing color schemes with designs that derive from the life size Extra 330 aircrafts. HCF Technology not only increases the structural rigidity of the entire plane to withstand breaking but also effectively reduces unnecessary weight, ultimately improving the planes responsiveness and flying performance.
