I've read and heard a lot about how Ground Resonance sets up and can quickly progress into an oscillation that upsets a helicopter. I've got references from Ray Prouty that lead me to believe that all helicopters, regardless of the configuration, are vulnerable to this.
A co-worker says that he's been to a conference where an expert stated that 2-bladed helicopters aren't susceptible to ground resonance.
Who's right?
In this vein, why did Bell change the landing gear configuration between the 206L and the 206L-4?
