Two Blade rotor systems + Neg G
Good afternoon, to those of you who are Degree Trained please forgive any Gram/spelling mistakes(especially long words) that said my question is for you very long and ProRotor Pilots who would be kind enough to help us low timers: We read nearly every day on the Pprune about the problems of Neg G, we know what the dire results can be (that is we should)so as far as I can see 99% of us adhere to the rules, but as one who does not own his own I like many others rent SFH on such as the R22 R44 and B206 all of them fall into the model range that are suseptable to Neg G damage, apart from looking into and up underneath the actual center of the rotor stem/transmision shaft, are there any other warning signs of possible previous pilot /flight abuse, obviouse signs are marks on the shaft but if you look at that area of shafting on all of these types there are marks caused by the rocking motion whist the Helios are parked in windy conditions, and supposing you get airborne with such an abused machine are there any dynamic signs that would point to immediate return to terra-firma, or by then would it be to late ? I know Lu will love this one but I feel that there must be something more than marks on shafts to indicate this problem area, or is it open to last man holding the stick gets first prize.
