RE: Which way do they fly Down Under?
well id rather have a nose cone hit me in the head rather then the bare end of a crankshaft, the end of a crank hitting you in the head at hi speed would most likely kill you straight out or at least give you nasty skull fractures, where as the plastic nose cone would no be much better but it has that crumple factor to it also its shape alone can in some case cause it to hit ur head and slide at an angle off it though the damage would still be serious. either way around it im not trying to cause arguments guys just thought id mention it to ya, and that round nut that you call an ama safety nut we use those on scale jobs, and if i remember we used to get them provided with the old merco engines, people used to despise those engines but i love them but its getting hold of them now, bags of power for such a small engine and they turn bigger props very easily but are not a revers engine.
