I've got the same plane (reviewed it for RCU) and it really doesn't need the flaps. But they can be fun too!!!!! The best thing to use them for is making slower approaches on your landings. The best advice I can give you is to simply get up about 2 mistakes high and start making landing approaches and practice deploying the flaps so you get the feel for how the plane is going to respond. Once you start pulling the throttle back and the plane starts slowing is when you deploy them. If the plane is moving too fast when you use the flaps it will balloon up and climb. But keep the plane up high while you practice and you'll get the hang of using them. Once your are comfortable with how the plane responds with the flaps down then you can start trying them on a landing.

Hope this helps
