RE: Center of gravity
There are two really tough issues here and both have been pointed out by others and my only addition is to combine them.
1. Learning orientation to fly on ones own... a very difficult task with a plane that looks to be a fairly hot sport plane... plain and simple... an almost impossible task.
2. Giving the plane a check out and maiden flight. Throw directions, throw amounts, balance, hardware checks, checking wing for warps, etc and then once in flight getting the plane in trim. A fast sport plane can be challenging for an experienced pilot familiar with his radio to get trimmed out if it needs very much trim... if trim throws aren't enough and it has to be landed out of trim... the landing requires a careful effort of even an experienced pilot.
These two issues in my opinion exponentially raise the difficulty factor to a degree that success would be in the miracle range.
Without question, I agree with others to let this plane rest until skill is gained with other aircraft. If you must learn on your own... I'd start with a parasol wing plane that is not overpowered and do it on a smooth air day. If at all possible, travel to have it preflighted and test flighted and trimmed. Once it can be flown well, then a trainer... then this plane.
