    It actually says in the piece... China uses similar looking Hydrants to American Hydrants

    I think he probably reacted to help danny and the footage after it cuts would either be him dropping the camera or it flailing about so wasnt worth showing

    Nah I reckon the video is real, look at the mirrors wobble at different frequencies in the hover, one of them looks really flimsy. I don't think they would put negative detail like that in a fake video

    I didnt mean the breather if that was directed at me (its hard to tell who you are replying to as you never use the quote function)

    They removed the drive shafts (and who knows what else) for the flying part of the video, probably too heavy with them fitted. (pause the video on the bit where you see a rear view on the track and there are clearly drive shafts and a diff) The flying car always was and still is a daft idea, yeah you can build one but then what?, does anyone seriously think someone is gonna take something that expensive and flimsy into modern road traffic? One bump and it'd be a write off even if repairable it would be under an airworthiness regulatory system,...so huge cost Concept always was nonsense

    Does it actually go into the filter?, perhaps a makeshift primer?
  7. Red
    Yes both types should be oiled

    Brendan, what is that black round thing with a rod or tube sticking out of its centre that appears to be directly behind the air filter element?

    eVTOL industry prepares

    Red commented on Admin's article in Articles

    Actually nev they do, in the same way a helicopter's rotor does (A helicopter in forward flight uses less power to maintain height than it needs to do the same in the hover)

    As I've mentioned in my experience it just works for a less than adequate time period. If you look at the installation manual, Rotax actually states fitment should include a supporting airbox, the omission of such in many uncertified aircraft is done for a variety of reasons, mainly space and weight constraints
  11. Red
    UK permit to fly, which allows the great majority of maintenance to be carried out by the owner, with some work (eg on the control system) needing to be signed for by a competent second person and some work like modifications needing approval by the overseeing organisation (BMAA, LAA) and sign off by an inspector

    I can't see it being fuel as it seems to effect engines that were run on various fuels, ethanol free/laced/avgas. I wonder if it could be hot cold cycles..hot when running then left getting cold soaked in hangers'''repeat every flight , quite temperature difference. I don't imagine engines in your part of the world ever see cold part of that cycle. I'm just guessing here.

    Strange indeed, over here its extremely commonplace to get splits, I think every rotax 912 sans airbox owner I know has mentioned it occuring to them at some point I wonder if climate plays a part?, though I dont see how cold damp conditions could lead to this, especially as the splits always seem to start internally

    Edit...I'll just use the ignore function

    If you have no airbox and just filters hanging on the carb throats I'd reccomend removing the socket and inspecting at this point Brendan, I took the socket of my new to me Jabiru engine that had just 9 hours on it but years of sitting around waiting for the builder to complete and it was starting to split, they split internally.....it seems to be a quite rare occurence in Jabs but its so easy to remove and check its worth doing on your 100 hour checks imo. Now if it was a Rotax 912 with no airbox...well Ive replaced them on one engine twice in a 1 year and actually had one split half way round and the carb fell right off luckily after landing, Jabs seem far more forgiving in this dept. as Nev mentioned cantilever mounting on a stub of rubber with no support for the other end of the carb is far from ideal, maybe your aircraft has a rigid airbox that end..if so disregard my comment it'll probably last hundreds of hours mounted that way.

    You've wandered off into aspects and vehicles I made no comment on so Ive no idea why you quoted my comment on cable barriers versus motorcycles and there obviously poor design in respect of motorcycle impact, just look at the things, low dow so if hit upright youd just highside into the oppossing traffic, or if you had already slid onto the ground it probably do major damage to a limb at best..and if you ended up on top of one of the posts..well thats something I've experienced at quite low speed and still broke 3 ribs and a collar bone.
  17. Red
    Wow, I just had a read up on those cable barriers, whoever designed them was either an idiot who didnt understand the physics behind a motorcycle and or rider impacting such a device or simply didnt GAF

    Risk compensation is very real, the person in his/her huge modern suv with full insurance feels so safe they are almost guaranteed to drive like an idiot Consideration for others could help balance out this effect but there is very little of evidence that quality exists in the majority of people

    As someone who once worked as a motorcycle Courier in the smoke (only did it for 3 months as 2 blokes in the outfit got killed on the job in that short time so I legged it) I'd love to see that very detailed study

    914 is known to have a substantial rpm drop on switching off one ignition circuit What are your numbers? https://legacy.rotaxowner.com/si_tb_info/serviceinfo/si-914-034.pdf

    TAS is a calculation, it's can't be directly measured. As far as the aircraft is concerned it always experiences Forces relative to its indicated airspeed.
  22. Red
    Vne will be an given at indicated airspeed?, 244 knots indicated is over 400knots TAS at 35000'

    Why are you are holding pieces of paper saying 14 oct 2023 in a post made a day before that date?
  24. Red
    That's good, over here the last availabe Ethanol free fuel (Esso Super unleaded) started adding ethanol last september, hopefully you guys get to have the good stuff for a while yet.
  25. Red
    Just a reminder to confirm the compatability of your fuel system when using Mogas containing Ethanol, I believe some Jabirus have Fibreglass tanks
