I'm not an electrical expert but I would use a 4025-16 if I was putting a Scorpion
motor in my airplane. I am currently assembling a Helios 90 pattern ship as a back up
for my Wind with a Scorpion 4025-16 motor, Castle HV85 ESC, and 3700mah 8s lipos.
It is the almost the same size as the Wind so I'll have a good comparison in about a week.
I use an APC 18x10e prop on the Wind so I'll try that first on the Helios and see how it works.
