Lubrication

It is important to lubricate the flex shaft of the

Formula Hydro with silicone cable grease after

every two hours of operation. Do not forget to

do this or flex shaft damage can occur. You can

purchase this silicone grease at your local hobby

store (PRB0100 or PRB0101). To lubricate the

drive shaft, follow these simple instructions.

m 1. Carefully note how the drive shaft and prop

are presently installed. This is important so

that when you have finished lubricating the

drive shaft, you can correctly re-install it.

m 2. Loosen and remove the 1.5mm setscrew

that holds the propeller shaft. Remove the

propeller and shaft from the aluminum strut.

m 3. Insert a hex driver into the hole located on

the flywheel to lock the crankshaft in place. Then

use an 10mm wrench to loosen the collet nut.
