Extra 300 would be one example. Generally you use symmetric profiles for acrobatic planes - as all profiles have their own pros and cons, and symmetric ones increase capabilities in inverse flight (and acrobatics) while sacrificing low speed and straight flight performance.

Can you tell me the name of a commercial plane with a symmetric wing cross section?
