I was looking for a robust freestyle frame and had read good things about the Smoother Operator, so I decided to give it a try. It's a tight build, so I'm not sure I could recommend this for your first build. It feels solid though so I'll give an update after I maiden it.
Also, I'll be using Flybyacademy 5s 1500mah batteries.
How do you like that flight controller, intrested in getting the 20x20 version when it comes out?
