Hi All,
Jim, yes zero-airspeed is what I meant by static conditions, and you're right about needing to evaluate the available overhead.
Oh yes, and you're too darned modest.

As far as RPM governed operation goes, I can easily say it will lessen the pilot's workload, but I already think airspeed control is easier with E-Power.
When well optimized, the exponential response time to a step change in load is about 1/4 second. This is the case with the Castle Phoenixes, at least.
The CL setups use no braking except for a hard brake at motor shutdown. Our planes are cleaner and heavier and lacking control-line drag we need the brakes going downhill.

Like I said, the high energy transition from pulling to regenerative braking and back to pulling, while the RPM is commanded to maybe 5500 is more than any of the ESCs out there are capable of.

I think there is a way around the problem, so that E throttle management is less of a handful.

later,
Dean
