actually- an electric motor -which has max torque at ZERO rpm -is a very desireable setup for driving a propeller -
far better than an IC engine when instant performance is req'd
I have flown both types a lot and the IC setup has far more lag in accelerating the prop.

If you take 2 identical dimension & weight golf balls - one with and one without dimples, and you hypothetically drop them off a high building i.e 30 storeys high on an absolute calm, windfree day - say onto a concrete pad below - which ball will bounch back quicker and which one will bounch higher.....?

Dimples on golf balls began when it was noted that the older beaten-to-death balls which at the time were covered in leather, if there was lots of surface damage, these balls flew further than brand spanking new smooth balls.
