RE: RC Plane And RC Helicopter Collide Mid-Air
Yes, someone is to blame. The airplane runway is for planes flying in a pattern in a fairly predictable way. That's a reasonable expectation. There are hardly ever midairs even when 4-5 planes are flying together because they all move in the same basic pattern. The heli guy put a stationary object in the direct flight path of a plane where there shouldn't have been one. The crash is 100% his fault.
Just so you know I'm not biased, I fly both planes and helis. I have a 450 that's a lot of fun and a Blade MCX for indoors, and I have 6 airplanes, both nitro and electric park flyers. I would never take my 450 out over the runway when a plane is flying for exactly the reason I stated- plane flyers aren't used to having to dodge stationary objects in their flight path.
