I have the Hacker in mine but if it ever gives me problems I wouldn't hesitate to put in
a Scorpion motor. I have a Helios pattern ship with a Scorpion 4020-12 and it is a very
sweet motor.....lots of power and very smooth.
I just removed a YS 1.60 DZ from my 2 metership and plan on installing the new F3A
Scorpion motor in it as soon as it's available.
