ma che pochissimi, ma perche' scrivete senza cognizione e senza documentarvi, io ho esagerato 5-6 voli, ma i motori vanno lubrificati ogni 10-15 voli ecco qua:

Once the bearings loose their lubrication, they can heat up and wear out very quickly. A small drop placed on each bearing about once every 10-15 flights is enough to maintain proper lubrication to insure the longest possible life for your motor bearings.
