I lost my roo on its second flight.....Im so stupid.....

First flight I had someone extremely good fly it and trim it for me. He
said it ws a little wild on the ailerons. But otherwise flew great, like all
the other Roo`s.
Well....my turn to fly.... It was EXTREMLY wild on the ailerons....and I
was over correcting when turning.... But I thought I could handle it...
I flew for about 4-5 minutes...... Then I made a mistake... Instead of
banking it onto its side to turn , I banked too much, and it was on its back
inverted. Because it was 8 in the evening, it was a little dark....verry
little dark..... then I lost orientation of it..... I did not se it was
flying inverted........so when I gave Up elevator to turn....it dived full
speed downwards.....But it was very high up. So I thought I would just pull
full elevator, and loop it.........I was wrong.....not high enough. Full
speed at around 300km/h into the ground.....everything destroyed... the
engine is completle destroyed.... Im a bit sad now :-(
