  1. Posta\u010duje minim\u00e1ln\u00ed d\u00e9lka ulo\u017een\u00ed v\u00a0k\u0159\u00eddle rovnaj\u00edc\u00ed se 6x pr\u016fm\u011br trubky.Trubka pro model akrobata 2,6m rozp\u011bt\u00ed je dlouh\u00e1 max.800mm.<\/li>\n
  2. Ulo\u017een\u00ed trubky je v\u017edy v\u00a0pouzdru,obvykle lamin\u00e1tov\u00e9 trubce.Prvn\u00ed a posledn\u00ed \u017eebro jsou nejv\u00edce nam\u00e1han\u00e9 p\u00e1\u010den\u00edm a je t\u0159eba je p\u0159im\u011b\u0159en\u011b nadimenzovat. Posta\u010duje zes\u00edlen\u00ed z\u00a0p\u0159ekli\u017eky 3mm. Pouzdro um\u00edst\u00edme hned za nosn\u00edk k\u0159\u00eddla a pohyb trubky omez\u00edme. Spojovac\u00ed trubku nezalepujeme, aby se dala vym\u011bnit.<\/li>\n
  3. K\u0159\u00eddlo pojist\u00edme proti vysunut\u00ed nejl\u00e9pe smy\u010dkou z\u00a0pry\u017eov\u00e9ho provazce s\u00a0h\u00e1\u010dky na konc\u00edch.<\/li>\n
