You can fly anything within the wingspan limit (2meters) and wt. limit of 5 kg. (11.2 lbs). Unfortunatley, the Ryobi is not going to help you fit into those paramaters. Its not to say that you couldn't fly pattern with a Ryans Rebel. I just don't think you could get one light enough to compete with. Go to a pattern meet or two, and get a feel for what entry level flyers are using. You might be suprised.
