I purchased the Tower Hobbies package several years ago. Very easy to fly and and very durable. I still fly it occasionally with the tower .46. ( I would not recommend this engine unless you read AAAALLLLLLLLL the threads and be ready to deal with a finicky engine. A good 40 is just fine. I told one of our members , when I was just getting fair at flying, that I wanted a plane to do some aerobatics. He took my plane up , did a few nice loops , flew it inverted and greased in it. Lesson to me: its mostly the pilot to a certain extent.
