After a small electrical problem (hall sensor) mine is up and flying my overweight 80 inch Extra.It's too much power for this airframe,but am looking into a lighter and larger Extra in the future.
It starts easy,idles low and pulls hard. I think my vertical speed is similar to my level speed
Here is a quick clip of the Taurus 52 on its third tank of fuel.
