Since I received my A&P last December, I really haven't done much with it. I've worked a little with my brother (Walt at EXPaircraft) and a few short term jobs.
Walt doesn't work on Rotax and only does a few things on RV-12's. I've thought about specializing in RV-12's / SLSA's and Rotax. I've looked in to the Rainbow Aviation course and Rotax specific training such as Lockwood in Sebring. I'm also considering building an RV-12 to really learn the details of the 12's (if I can get my wife to approve

).
The big question for me is whether there is enough demand for maintenance service to justify the cost of the training.
