Have to start out with a trainer?
I would strongly suggest you purchase a trainer. There is a lot more to learning to fly than just flying in a circle. I would suggest a Sig LT40 as a possible trainer. Equip it with an OS 46FX and you will have a plane that will satisify your needs well after you solo. The OS46FX will be an engine you can you use in your next airplane. I have instructed several students with this plane and they all loved it. Give it a try.
