These are fixed pitch, so no 3D with them. Free is good to a point until you need to find parts for them...and you will need parts pretty quickly (even with the parts to build 3 more) learning to fly is lots of fun but costs in parts. You should look into getting a good sim and use it to learn the basics while learning to fly the real things.
I can tell you from my experience with the Axe CP that tail motors are a hassle to have to deal with....you can learn to fly with them but they can cause more issues than there worth at times.
Just my .02 cents
