The LOGO 550 SX is the first member of the next evolutionary step of our popular and proven LOGO 500/550/600 helicopter series. Underneath the freshly designed canopy you find an improved version of our tried and tested chassis, which now offers a battery quick release system and considerably more headroom for flight packs below the counter bearing. The chassis will of course be available as upgrade kits for all existing 500/550/600 size LOGO helicopters. - 550 mm main blades- 6 S Lipo mit 4500-5000 mAh, a luminum rotor head yoke with 8mm spindle shaft - light und durable chassis fiberglass reinforced frame with battery quick release system- direct servo link to the swashplate- Hollow main shaft with 10mm diameter- Herringbone main gear with 153 teeth (module 0.7)- Motor counterbearing with additional main shaft support- colored fin set in neon red, matched with the canopy- Extra-strong 22 mm diameter tail boom- Detailed airbrush canopy in neon red
