I got lost back in the time I was expected to know all the interworking of a cereal bowl compass in order to use an RMI for figuring out what direction I was going.
Sorry, didn't intend to confuse you or anyone else. Just tried to provide an answer to Lonewolf_50's specific question.

If it's any help, the simple version of what I posted is as follows. There is an advanced type of alloy gear steel called C64 that has recently been developed which can safely operate at temperatures ~500degF higher than steel gear alloys used in current gearboxes. Using this advanced steel alloy to upgrade certain gears of existing main rotor transmissions could likely provide a significant increase in loss of lube performance, at a reasonable cost.

Does that explanation make sense to you?
