Hate to admit it but I've crashed an R/C plane or two in my time
Flying one is without a doubt not easy to master. The controls can be finicky. Not to mention the factors that are out of your control entirely: The smallest gust of wind can ruin your day with these light models, especially if there is a body of water nearby... *ahem* Not saying I
Seriously, you can pick up some really cheap ones at Radioshack to play around with and you won't feel it in your wallet when you crash it the first time. I've never heard of an enthusiast who doesn't have at least one nasty crash story.
Doing so will give you a greater feel for what you're up against, especially when trying to consider scenarios like the gust of wind I spoke of earlier. Think of it like this: It's like taking your drivers test for your license- much easier to do if you've actually driven before and not just read about it or played Grand Turismo a few times.
