Superlight, extremely rigid mainframe:
The mainframe consists of a right and a left frame made from glassfiber-reinforced polymer. A number of components which are usually separate parts are fully integrated into this frame, and do not have to be bought separately, for example bearing case, battery tray and servo mounting plate. There is ample space for any brand of available battery. The mainframe offers enough room for motors of up to 56 mm in diameter.
