I thot 25 words were the limit for the daffynition.
But - to slightly expand-
the power curve of the engine/motor,will affect all of this.
drama tick ally.
My foray into electric power has shown this .
The props can be accelerated or "decellerated " -almost instantly . so take off "power is instant and braking power can be predicted.
I realize this throws more bull fodder into the question.
EXAMPLE- my ERATIX uses a 14x 7 APC weighs 3.75 lbs
take off thrust is akin to a slingshot
ditto for in air acceleration yet speed at full power is at structural "yellow line" in a heartbeat. for landings you can drop it in at 10 mph
obviously the total package mix is good.

Heck, I'd say it actually points through a fair amount of the fodder.

One reason our models fly the way they do IS the engine's power curve for sure. I'm voting for at least one of your candidates.
