I will be interested to see the hot and/or high performance. With naturally-aspirated petrol engines, you get a triple penalty when hot/high: the engine produces less power (because there's not as much air available for combustion), the propeller loses effectiveness (because the air is thinner), and the plane has to be going faster for takeoff (also because the air is thinner).

Presumably the first will not apply to the electric motor; it'll happily produce full power at 40degC or at 6,000ft. This may translate into a pretty significant improvement in takeoff performance at hot and/or high airfields.
