    The colour picture on page 14 of the construction manual shows the assembled tail shaft with 90 degree offset. This is different to the line drawing in the construction manual showing the holes in line as Joe has mentioned above.So, there is a discrepency in the construction manual....Hmmmm ??? ???BlueHi Bluey,It is interesting to note that the Brumby Helicopters website is faulty and when you want to peruse what"s in the box, only the first two links work correctly!I have tried to look at the parts pictures that would be in the "box" to see if the coupling flange is pre-drilled at 90 degrees offset or both holes in-line, but, the link isn"t working!There is more than one way to skin a cat, though! In your reply, you quoted page 14: "The colour picture on page 14 of the construction manual shows the assembled tail shaft with 90 degree offset. This is different to the line drawing in the construction manual showing the holes in line as Joe has mentioned above.So, there is a discrepency in the construction manual....That was an interesting observation, because if you look at the parts pictures in the phase 2 of the construction manual: http://brumbyhelicopters.com.au/_ima...ail%20Boom.pdf ,on page 2, you will note that the coupling flange is pre-drilled in line rather than 90 degrees offset!! ??? ??? ??? ???What is even more interesting, when you look at the version of the manual!!! (Rev: 0 Page 2 of 12Date: 07/02/2011)!!!!!!The first flight of the CH7 B was according to OzCH7b"s Public Profile, in April 2011 at Caboolture!

      Hi Joe.Very interesting observations indeed. The time line comments are particularly telling.Yes, only time will tell.I have been looking at a few single seat kits, and the helicycle http://www.helicycle.com/ interests me greatly.The price is about $45K landed with engine (Turbine) and the factory holds key rotor head components until a company rep arrives, totally inspects the construction, strobes the blades and flight tests the machine. That kind of factory support speaks volumes.I am also looking at the mosquito as well, but am waiting for more impressions from owners of the turbine version.All the best JoeBlue

        Hi. Blue!Talking about interesting observations, Look at the picture of the tailshaft flange attachment in the topic, "Single Seat Helicopter to drool over. « on: October 29, 2011, 16:09:40 PM » "

          Sounds like it is time for an AD to be issued from the factory.I am just glad no one was hurt in the accident.The fact the construction manual has 2 versions of the drilling of such a crucial part shouts "lawyer" to me. Bad news all over if that happens I feel.I do like turbines even though they guts the fuel

            I dont think he has been, i think they just put it all down as pilot error. Also it was a lemmon from the start he told me. and he was very disapointed in it also.I would like to know who "THEY" are! Are "THEY" saying that the pilot reached around and snapped the shaft whilst 40 feet in the air? Must be very agile!!

              I would also like to know all about "they". " They" seem to know a awful lot.

                    Brian,I understand and agree with some of what you are saying. What concerns me, more than anything else, is the wall of silence around the accident/crash! Having looked at the assembly and the construction manual, which appears to be suggesting the drilling of the two tail rotor shaft flange bolts in-line in one place and 90 degrees offset in another, including pictures of same, for the first one assembled at Caboolture (is 90 degrees offset), then being presented with a picture at Single seat helicopter to drool over: (http://www.asra.org.au/smf/index.php....0;attach=5685) which is clearly drilled in-line!End of quote.Ahh, that wall of silence, can be infectious at times . I reckon down the track the incident will make light of day. ASRA plays no part in light sport helicopters at this stage so we have no info other than the rumours that are going around.With 9 units heading to work, it wont take long for any dificiencies to rear their ugly head [ if any]. If you approached Tony Carmody directly, you would most likely get an answer.Quote reminds me of a factory tour (as a budding toolmaker) of the Porsche factory at Wolfsburg in 1965. There is a driveshaft of approximately 12 inches long in the museum. It used to be in an experimental Porsche which eventually turned out to be the 917 with a flat 12 cylinder engine. This car developed about 1500 HP. When it was taken out on the test track, the driver planted his foot on the throttle. Unfortunately, the car did not move. The torque produced, twisted the hollow driveshaft, which made it pull the spline out of it"s housing. The driveshaft then just dropped on the road. It is the museum piece on exhibit.End of Quote Years ago a truckie mate showed me a bit of tailshaft off a truck that had a bogged trailer [ 40 tonnes of grain], the prime mover had loads of horses but when the driver dropped the clutch to make the truck "jump" something had to give and the tailshaft twisted like spaggetti. I was more than a bit disappointed to see that the tailshaft was hollow

                          So, why is there a wall of silence,Well, if i was involved in any way in producing any publicly available machine, id shutup too.This internet thing has its pros, but theres alot more cons.Any dichead can say anythn he likes bout anythn, with no consiquence.Its the reader who decides on wots true n wots crap.Personaly, i believe nuthn i read on this thing. Certainly not to the extent of trusting the info with my life, or coin.This thread so far is a prime example of wots crap.The last place you go for the truth is the dealer or the internet. Ones bias and the other has no consiquence.
