The LOGO 600 SE is a special version of the LOGO 600 series with a longer tail boom. This allows using longer main rotor blades of about 690 mm in length. With the considerably larger rotor disc and nearly the same all-in-weight, the LOGO 600 SE is a very lightweight heli in the 690 class. The revised version has the counterbearing linked to the main rotor shaft and the one-piece head yoke oft he 600 SX series as well as a freshly designed canopy. Below the canopy, you find the battery quick release system and considerably more headroom for flight packs below the counter bearing.
