Lubrication
It is important to lubricate the flex
shaft of the ThunderCat 31 with
silicone cable grease after every
two hours of operation.
You can purchase this silicone grease at your local
hobby store. To lubricate the drive shaft, follow
these simple instructions.
Carefully note how the drive shaft and prop are
factory installed. This is important so that when
you have finished lubricating the drive shaft, you can
correctly re-install the drive shaft.
Loosen (do not remove) the retaining nut by
holding the collet with a 17mm wrench and unscrew
the retaining nut with another 17mm wrench or
crescent wrench.
Carefully remove the drive shaft.
Liberally lubricate the entire length of the drive shaft
with silicone cable grease as shown.
Carefully re-install the drive shaft, making certain
that you insert the flex shaft 7⁄16” to 1⁄2” into the
collet and secure.
