RE: Scorpion motors for 2x2 model
I'm interested in this too. I'm about to get a Scorpion 4035-250 and run it on 10S in my 110 size pattern ship. A lot of guys are using Scorpion motors in the Sebart Wind 110, though mostly the 4025 on 8S.
Their "About Us" page pretty much says that the motors (and company) is pretty much designed around electric pattern competition, and their reputation is to be lighter and more powerful than Hacker.
