Youwill needalsothe:
CAglue, CAglueactivator, sharp(modelling) knife, 150mmextensioncableforservo???. Tocompletethemodelyouwill need:a
receiver(MZK), servos(WipontW-060),acontroller(TMM-1210-3orJeti 12),anaccumulatorbattery(3 LiPolcellsof 640-1200
mAh),amotor(HCS-80/2Eorsimilarof about80 Woutput).
Descriptionofthemodel:|
ThemodeliscompletelymadeofEPP andhassomecarboncomponents. Withitsweightbeginning at 250 gramsit isanideal
modelforflyinginanysuitablespot(e.g. aschoolplaygroundorinthestreet).Itisintendednotonlyforexperiencedpilots,butalso
fortheadvancedmodellers.Topowerit youmayuseamotorfromourproduction,e.g.theHCS-80/2E,andthree LithiumPolymer
cells. Thankstoawell thought-outdesigntheconstructionwouldtakeonlyabout90 minutes.
