Unfortunately no. They didn't sell as was hoped so they stopped carrying them.

Earls post and the link that he shared get you there easily.  Also, as Earl pointed out, savings in mAh are highly dependent on your existing habits going into this exercise.  More than anything, it's about achieving very good throttle consistency with reduced pilot workload.  Saving some battery and being able to configure to always ace the noise test *legally* are additional benefits that fall out of the throttle leveling algorithm.

Given our ambient starting temp is lower than the temp where lipos are most efficient, a gradual increase in lipo temp can offset power loss as the pack discharges.  Depending on ambient temp, discharge rate, effectiveness of cooling air, etc, higher C batteries may actually show a more pronounced drop in power.

Maybe I was not as sensitive in the past to the throttle’s effect between the start and end of the flight as you probably would be, but I suspect that the HOT weather will show its benefit to me on verticals near the end of the Master maneuver schedule.

Reducing the compensation factor increases the peak power available with greater likelihood of the power dropping off deeper into the discharge.  Of course this assumes a reasonably healthy setup to begin with.

However that will probably change, since we are getting into HOT weather here and will be using more mah in a flight than in the cool weather.
