Oh my god I want to make fun of all of you.(except the previous post I didnt read it till after i posted this) Some of you have made good points though. check your arfs for piss poor workethic and quality control. range check is important. when you get to the field and you cant fly because there isnt a open channel that you happen to have crystals for then use your 2.4. If you cant fly at your local park due to radio interference at least you checked before you hit a little kid with your plane(how do you think i ended up with a 2.4). Most crashes are preventable in hindsight and totally unexpected in forsight. A solid routine for build(arf or kit dosnt matter you still have to put the thing together)will help prevent most operator error. And always remember its never your fault its always the airplane/radio/runway/winds fault.
