RE: the rational of trimming
Brian,
I think Dick meant max torque at zero rpm when the motor is deadheaded and at full throttle. Motor drawing and controller delivering max amps under this scenario. Not for long tho!
Some electric set-ups are truly amazing in their easy delivery of power to the prop. What Dick says about the vertical up line is something I've observed with electrics too.
To get similar output from wet power, we may have to resort to belt driven and electronically governed gas power. Not in my life time tho, unless I do it. I like my gasoline powered models just fine, eventhough it's direct drive and of marginal tork at mid range. I see no reason to change what I do right now.
