I have been following the story about the race plane crash in Reno.The most recent development is how these guys mod the planes to make them faster.One thing this guy did was over the yrs to cut off 10' of the wing span.From what I read it is common to do that.Other thing that is under investigation is the trim at the tail of the plane.The reports I read is there isn't much of the original plane left.The question I guess for the novice is if the mods still leave the planes safe/stable.These guys that fly them are going 500mph with nerves of steel low to the ground.
