The Extra 300 ,if you put enough power up front, can do fine. Just set it up with smaller throws than 3-d and give some of the maneuvers a try.

IN all fairness the Extra has a shorter moment than most pattern planes (the distance from wing to stab) so it won't be as smooth as a purpose built pattern plane. After you've tried it some ,see if you could get a chance to fly a pattern plane . The distance from the wing to the stab is longer to have more stability in pitch. The feel is quite different.

So set up the extra and fly it for awhile. If you enjoy pattern type flying then you could plan on your next plane being a pattern type plane and you could set the Extra up for 3-d(more throw & more rearward CG). Not many planes will do 3-D & Pattern both very well so most people build seperate planes for each purpose .
