I'm looking to buy myself an RC something for Xmas... some thoughts are as follows.... my initial thought was maube something I could use indoor in winter or outdoor in winter in the snow/slush.... or something fun for nice weather alternatively. What does everyone think I should buy? Any other suggestions? I'm a decent plane flyer but need more practice. Love helis despite their hard. Can't go wrong with cars or crawlers.
