There are creative ways to reduce the cost of this hobby.

First, avoid the heavily marketed, gimmicky products, such as the Nexstar RTF. It's a fine trainer, but there are other choices that can be had for significantly less $. For example, I've posted the price of a package consisting of the Tower Trainer, OS .46 LA and Futaba 4YF in a couple other threads this week. Total cost is around $220. Even if you have the misfortune of totaling it, the radio and engine will probably survive and a new plane is only $65.

Also, focus on the bare necessities with respect to tools and field equipment. There are many things, such as electric starters, that are optional, despite what some may say.

Another viable choice is small electrics. If you stay conservative, the up front costs are a bit lower, but you won't spend as much for field equipment and fuel. If I want to take my Slow Stick to the field to fly, all I need is the plane, transmitter, spare props, wrench for the prop, batteries, and field charger. While the electrics are nowhere near as cool as glow, and you don't come home with the lovely scent of burnt glow fuel, it's still flying. I know some people who have a great time with small electrics.

And yet another possibility is the careful acquisition of second hand equipment. If you can find some stuff locally that's in good condition you can save lots of $. However, don't rush over to eBay and start bidding on things you can't see from sellers you don't know. There are some real bargains out there, but there is also lots of junk. As a beginner, you don't need to be dealing with equipment problems while you are learning. Ideally if you're going to purchase some second hand stuff, you'll have an experienced person check it out first, or buy it from someone you can trust.
