I didn't see any bad comments. All I'm reading is people trying to help. Listen to their advice. By reading your posts, you clearly have no idea what you're doing. As you said yourself G2 doesn't help you with starting. You can ask all the questions you want, but if you don't listen to the advice, whats the sense? RC planes/helis are not toys. Anyway, I hope you get it going,,, one way or another. Also if you bought the plane off ebay, then I would DEFINATELY have someone experienced check the plane and engine out.
Good Luck!

PS if you do have every single size allen wrench available, and none fit, then your screw is stripped.
