The weight obviously screws into the rotor. Are you running long m6 bolts that run through the entire rotor with nuts on the other side (not sure if they would fit)? Are you loctiting the bolts into the rotor? I had some long m6 bolts that maybe run halfway into the rotor. Probably not good enough. I just don't want the thing to fly off. I should have taken a pic of the inner rotor weight mounted. It at least looks cool.
