paramotor propeller balancer

should fit atom 80, top 80, moster 185 and corsair props. and probably most others holes may need reamed out to fit your prop bolts. I made them exact size in CAD but printers usualy undersize the inside of a hole. a drill bit should do the trick

you will need two 608ZZ bearings and wash the grease out of the bearing rollers with alcohol to reduce the friction
