Section 10: Lubricating the Drive Shaft
Lubricating the flexshaft is vital to the life of the drivetrain . The
lubricant also acts as a water seal, keeping water from entering the
hull through the stuffing box .
Lubricate the flexshaft, propeller shaft and all moving parts after every
2–3 hours of operation .
1 . Use either two crescent wrenches, two 10mm wrenches, or a
combination of either to loosen the collet nut .
2 . Remove the 3mm propeller strut screw and remove the drive
system by sliding the flex shaft out of the stuffing box .
Leave a 1mm–2mm gap
here to allow for flexshaft
shrinkage under load .
3 . Lubricate the drive shaft with PRB0100 Waterproof Marine
Grease (see your local hobby shop) . Reinstall the drive shaft in
reverse order . Be sure to reinstall the nylon washer between the
universal and the stuffing box .
Note: Running the Formula FASTech 26 Brushless EP RTR in salt
water could cause some parts to corrode . If you run the
boat in salt water, rinse it thoroughly in fresh water after
each use and lubricate the drive system . Because of its
corrosive effects, running RC boats in saltwater is at the
discretion of the modeler .
