The Duraplane is fairly cheap and if you do break something, they sell replacement parts.

I learned on one and had a lot of fun.

If your breaking props while landing, remember to fly all the way to the ground. I was cuttin the power back to idle and trying to glide to the ground. More often then not, it stalled about a foot off the ground. This causes really hard nose landings and the gear will bend enough to let the prop hit the ground. Instead, you should keep enough power to prevent the stall until after the plane touches the ground. Then cut power.

Make sure any plane you learn on has ailerons. It's a lot easier to learn than just rudder/elevator.
