A decent ARF (Almost Ready to Fly) will run about $100-$150. Radio and gear is another $150 for a basic setup. My plane was built by me in about three months (nights and other free time). You do need patience and understand that things will break. Here is what remains from my current gliders predecessor.
My video gear is design to give me a live feed on the ground and transmits about two miles. I can and will hook it up on the ground to record some of my flights. So far, my record altitude is about 2300 feet above ground.
Find a local field and see if there is anyone willing to give you some stick time. Also, if you do get a glider or other plane, be sure to stick with the club and let them help you learn. It makes all the difference in the world.
