The major difference between a Pitts and a Stinker is that the Pitts performs really fun and wild aerobatics. The Stinker does the same thing but with precision. Extremely predictable biplane. Don't mistake the last to mean it's a soft flyer. It reeks of performance.

The only reason you don't see more of them is because they take a while to build, and don't come in ARFs'. It will be more than worth the effort. Use the biggest 4 stroke you can get your hands on, but that may still be a little short on power. The Moki 1.8-2.10 or the MDS 2.18 would be the glow engines of choice. You will need the weight up front because of the short nose moment arm.
