Very nicely done, JR. As you probably know, the wobbler is the engine form most often recommended for folks who are starting out in the engine building hobby.

The wobbler is simple and dependable. They can be surprisingly powerful given their simplistic valving design. Plans for multi-cylinder versions exist where one cylinder won't do the job.

Folks looking for model engine plans should be aware of the John-Toms site...
