Duraplanes tend to come out on the heavy side. The O.S. .46 LA would probably be a better choice than the .40 LA. A little bit of extra power could go a long way toward improving the flyability of the Duraplane trainer, especially if you're taking off from a grass field.
This Duraplane trainer is a kit, you will also need to purchase covering, covering tools, and other accessories to complete the airplane. You will need a radio system, and you will need field equipment for starting and maintaining the plane.
Why not consider the Thunder Tiger Easy Trainer 40H w/ Side Kick flight accessory combo?

The box will contain just about everything you need to go flying except a jug of fuel!
You'll have an instructor to help you. Instead of purchasing a plane that is designed to crash well, why not choose an aircraft that is designed to fly well instead?
Good luck and good shopping!
