theres nor alot of differences, The Squadron has an updated tail box, Fiber frame and the servo mount differently, The Ver. 2 has a metal frame, different tail and the servos mount different. But basically they're the same but the Squadron has better performance because its a bit lighter. Oh and the Version 2 comes with Plastic blades and the Squadron uses Woodies. I say get the Ver 2 because it $40
I can't wait to get some extra money so I can buy me a few. Its hard to be scared to crash when you can buy a whole kit for $40.
