I took my Alpha 40 up for it's first flight last night. Went pretty good. The Alpha 40 is heavier than my electrics (my electrics are not very big) the extra weight mostly translated to a longer take-off. In air, flight was pretty much the same. There was a slight difference in the throttle. Electrics seem to have an instant throttle up whereas there was a very slight delay with the glow. Now, that slight delay could have been attributed to the weight. Of course, the Alpha 40 is a trainer, so the flight envelope was not quite the same as some of my electrics.
