To make the wing tubes you need a 6mm outer diameter carbon fibre tube, on mine the blades are 25cm long but you can experiment to make them longer or shorter. the aerodynamic surfaces are made of 5mm foam and are 55mm wide at the wide end and 30mm at the narrow end. For sealing I used eva rubber cut to size and to make the valve to let the air escape I used a marble of about 12mm diameter. https://www.youtube.com/watch?v=hMdcSJ5o7IY&t=1s&ab_channel=MrCuervoRC Para hacer los tubos de las alas necesitas un tubo de fibra de carbono de 6mm de diámetro exterior. En el mío, las palas son de 25cm de largo peor puedes experimentar a hacerlas mas largas o mas cortas. las superficies aerodinámicas están hechas de poliestireno extruido de 5mm y tiene un ancho de 55m en la parte ancha y de 30mm en la estrecha. Para sellar he usado goma eva cortada a medida. y para hacer la válvula que deja escapara el aire uso una canica de unos 12mm de diámetro.
