In Free Flight competition models we use a special clockwork timer that shuts the engines off amongst other important functions. These timers are very finicky in regards to oils used to lubricate them. At a recent meet I was able to demonstrate the qualities of Boca Bearings High Speed Oil. The timers oiled with the so-called "special oil" ran 20 seconds per revolution and slowed down within 4 minutes of run time. Cleaned and re-lubed with your oil the timers ran a consistent 15 seconds per revolution and run time extended to a full 7 minutes which is a healthy safety margin for our use."
