around 3200 watts, enough for the Sportsman Pattern
That's enough for
anything![X(]
Seems pretty high on the amp draw at 84 and a little low on the prop pitch with a 20x10. Many electric set-ups use something like 21x14 or 20.5x14.5.
But I am not at all familiar with the Scorpion motor you mentioned. I thought it was an Axi.
Good luck on the maiden. This thing is built well and mine needed only a couple clicks of aileron and one click of elevator to get it grooving pretty nice right off the grass.
