Cole Posted September 8, 2006 Report Share Posted September 8, 2006 Okay guys and Girls, heres what I need to know. -The 212 and similar Helis make a snapping sound when theyre flying in sevral different situations. Some schools of thought state that the advancing blade is actually breaking the speed of sound, however from other schools of thought I hear that it is the next rotor passing into the inhearent turbulance of the airfoil prior. Let the games begin, I hear this is a "Noone knows for sure, many theories exist" topic. Have at'er Cole :punk: Quote Link to comment Share on other sites More sharing options...
