I have a brother in-law whose in the hospital right now with second degree burns to his legs. His Savage X exploded on him while he was spraying the chassis with NITRO BLAST engine cleaner. The engine was off. The gas is still in the tank and I'm thinking that it was the engine cleaner. However his wife was indoors when she heard a loud explosion. When she went outside, the neighbors were throwing blankets on him and hosing him down with water. I don't see how that could of happened with just the cleaner. I'ts more of an airspray to blow off the dust.
Anyone in RC land know what it could be, or if anyone had a similar experience? I'd greatly appreciate your feedback. And by the way, I know I spelled California wrong on my user name.
