Subject: [FlyRotary] Re: Oil
Cooling/Pumping
Joe,
Idea probably has merit but it adds another failure mode (electric
pump
I presume)......I would not want to use it for primary oil cooling but
can
see potential as a auxillary cooling system for part time use during
those
max power climbouts and / or hot weather use......IMHO
