I assume you are thinking of the DL-50? It is quite heavy for use in a pattern plane. Lots of power, though. I would suggest maybe trying a Brillelli 46GT instead of the DL, it is significantly lighter and would be a better fit. Less power, but it should still have lots for your uses. Virtually the same price and great customer service from Scott.
