| you are not aloneI had an electric concept and an X-cell with only the throttle chanel reversed between the two models.
So I did the pre-flight, cyclic and tail looked good, started the X-Cell, and whoops, full throttle. I was holding the rotor head good and hard but I will say the OS 61 knows how to put up a fight. Anyways, I got the fuel line off and it stoped with nothing more serious to report than a foul smelling smoke from the clutch.
What I'd like to add is this: 4 months later and the X-Cell fell out of the sky from about 40 ft following something of a reverse auto. It was kind of weird, heli aquired head speed on the ground as normal, went up, normal engine tone (governed by GV1) but unbeknown to me (until it was too late), the blades had simply lost energy on the way up and stopped turning - certainly nothing left for any kind of controlled auto descent (repair bill = to 1.5 Raptor ARTF kits). Why? Well like a damn fool after the smelly clutch incident I failed to check and replace the clutch lining. On further inspection, the interior of the cluch bell was bright polished ali with trace elements of clutch lining dust. Embarrasing, yep you bet.
P.S. Regards the adjoing thread re knife edge manoevres infront of a crowd (or pilot) - if a heli was on the verge of this condition it would likely not pull out of that stunt before it hit - or you'd have to use the inertia to bail out over the heads of the crowd/judges into the car park.
