It's not my first plane - I started with a Stick and flew it for a while - the Edge was my next plane after my Stick. The engine, receiver, everything was build over from my Stick. So I'm not totally new too RC planes - I just put it in beginners thread because I didn't know where else.

Quoted from Charlie:

"School of Hard Knocks Lesson #37: If it ain't running well on the ground it will not improve on its own with additional altitude."

Believe me I know this lol - but I just never listen too myself.

"Lesson #72: On takeoff . . . or most other maneuvers . . . advance the throttle slowly and smoothly."

I do this.

"Lesson #73: Heck, don't slam ANY of the control sticks and sliders at any time. On vs. Off is for two-position switches."

This I know too.

"You can adjust the "main" needle valve (high speed) for hours and hours but if the low end is bad you'll never get a good transition from low or middle to high speed. Most engines have a bit of tolerance for both settings. Some are very finiky."

Yes and I have no clue about the low end adjustments - that's the reason for me taking it too the hobby shop. The guy actually picked it up a couple of minutes ago and said they will sort it out - I don't have too worry. He also thinks its the low end which needs too be adjusted. But they'll put it on a bench and do it.
