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 two 10mm wrenches to loosen
the collet nut.
 2. Remove the hex screws holding
the prop strut in position. Remove the
entire assembly with the flexshaft.
Carefully note how the drive shaft and
prop are factory installed. This is import-
ant so that when you have finished
lubricating the drive shaft, you can
correctly reinstall the drive shaft.
 3. Remove the drive shaft by sliding it
out of the stuffing box.
Wipe off all dirt or debris from the
flexshaft and liberally lubricate the entire
length of the drive shaft with silicone
cable grease.
Carefully reinstall the drive shaft, making
certain that there is a 1–2mm gap be-
tween the prop strut and the drive dog to
allow for flexshaft shrinkage under load.
Note: Running the Blackjack 26 SS
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.

Leave a 1mm–2mm gap
here to allow for flex shaft
shrinkage under load.
