Hi, good wishes to all
I have a problem where my Razor will not lift off and just spins, I have only replaced the main rotor blades and it flew before that. On inspection of the lower blade holder, it appears to be able to spin freely - should this be the case or should it be fastened to the lower shaft, there appears to be a small hole part way up the shaft but nothing screwed into it. Should the lower blade holder be pinned to the shaft or does it turn under centifugal force, if this is the case i feel the lower blade set is not acheiving enough head speed to contradict the upper set. Any help on this matter would be greatly appreciated as the manual isnt much help at all.
