    Yes I agree and worse of all they seem oblivious to what is required and the challenges in the territories they are likely to gain more traction. I was involved with a program in the middle east and by far the biggest challenge aircraft wise is heat. An enclosed cockpit will require air...

    Blade Flap, also called Blade Sailing in UK.

    Nice work. In the Calidus accident with 200rrpm pre-rotation obviously the causal effects were pretty well discussed for this particular accident but some comments on Calidus snags. In general terms I always recommend people pre-rotate to beyond 200 in Calidus and for that matter Cavalon...

    Agree fara - I hear the low cost alternative with possibilities in Asia or Africa but why take a 600x?? Take what already exists. Robbo helicopters are a sales tour de force but in mature markets they are trainers & private aircraft first.

    Hey Leigh - yes agree on the effort side although the Fairey aviation efforts with the Gyrodyne, Rotordyne were of a significant order of magnitude greater and still failed! Now I take the point different time but why will it be different this time? Fairey it must be remembered were already a...

    I'm not sure what drives the business case for these entities beyond what appears to be access and availability of capital and if that sounds negative on the 600x I don't mean to be, its just that from where I'm sat it seems we are doomed to repeat failures of the past. Happy to be shown the...

    Fatal - Cavalon G-CKYT, Scotland, UK

    I can hear everyone and we are in danger of shooting the messenger. What I personally am saying you can read for yourselves above and to re-state on the basis the thinking thus far is that it didn't fail because of defects [and that is re-enforced by the lack of any airworthiness release in...

    So we saying that the +3 -0.5 number is not a limit?

    Fatal - Cavalon G-CKYT, Scotland, UK

    The Cavalon POH suggests:- Not sure the weight of the aircraft at the time but I suspect that it was towards the high end given the process most go through when sending students solo. Sustained positive g at those values is I agree a challenge although a peak g with an aggressive pull...

    Fatal - Cavalon G-CKYT, Scotland, UK

    We can all read the exact wording when the AAIB release their final report but for the avoidance of doubt with the "investigation focused on understanding the circumstances which led to the rotor head separating in flight", a year passing and those engaged with the AAIB so far on the engineering...

    Fatal - Cavalon G-CKYT, Scotland, UK

    We have talked the safety of gyros around a few times and whilst it never seems to lead to much agreement it is fact that a fixed wing aircraft is able to fly through use of a structure whilst rotary wing aircraft through use of a mechanism and a structure is inherently safer than a mechanism...

    Fatal - Cavalon G-CKYT, Scotland, UK

    I've been told the failure is more likely through overload, fairly well commented upon in the UK and accepted as such for much of 2021 which makes the AAIB statement interesting.

    Fatal - N419LB Cavalon OK

    Pilot operating handbook, maximum all up weight etc were not listed? Genuinely surprised and perhaps a red flag to what gets taught and surprised some of them were new to you but I suppose it goes to show you should never assume, which is quite apt in the context of this post. Sorry for any...

    Fatal - N419LB Cavalon OK

    Yes of course but the pilot operating handbook doesn't give a the take off distance required with varying headwind components so 10ft could be 0ft, 1ft, 100ft or any number anecdotal evidence may decide. To the points others have made the number that sticks in the mind is the optimistic one...

    Fatal - N419LB Cavalon OK

    +1 and now if you listened to Synder the 60ft is now 10ft with Cavalon One real big issue in the small / niche world of sport gyroplanes is that urban myths or metrics that should come with huge health warnings or caveats are told less often than they should for fear of putting a head above...

    Fatal - Magni M24 near Butzbach, Germany

    Likely the fuel fire comes after the oil fire given the disruption of the oil lines etc and the potential for the turbo to cause things to flash. Just a view but fuel bladders used in the military and motor racing are very easily acquired, but they are not cheap. These are about the best...
