Ancient R,
Why the techiness? whilst Pprune Rotorheads is for the Pro's, there are many private pilots who take much quality info from this site, I for one have found any question you care to ask on Rotorheads will be answered with deep involvement from many WORLDWIDE vGood pilots, ... Chill out man we are'nt all A1 experts.....!!
