Yes ATIS - Automatic Terminal Information Service, Generaly found only on large airfields with commercial activity in my country, do smaller aerodromes have it in Aus?
-
If your altimeter is calibrated and correct and you are parked at a spot that has the same elevation as at the centre of the longest runway (or you know for sure elevation at your position) then yes it should match. I fly mostly in and out of farm strips with of course no ATIS so the procedure I adopt is as you mention dial in known elevation before taxiing then check when Im in vicinity of a airport with ATIS that it matches Saying all that, anywhere that has an ATIS is likely to require you speak to them before departure and that info will be given anyway (speaking of UK, though should be same..... I must remember to add that disclaimer)

Astounding -
I explained this to facthunter some time ago Danny but he won't listen Whatever I'll report back on the starter I've ordered when I get to trial fit it and try get the thread back on track.😁
-
....and just sacked 10% of their workforce
-
Thanks Onetrack, you wouldnt get me up in it either
-
Indeed It's a wonder really that the design has proved so reliable in the millions of motorcycles its been fitted to in the last few decades They really should have given you a call before releasing it to the world, you could have told them to fit a pin in the end
-
Presuming you mean simply by using electric motors then yes of course which is likely why you don't see many efforts at trying to make ICE multicopters. I'm pretty sure the machine shown was basically an engineering exercise from someone with way too much time to waste. As onetrack implies, the start procedure must have been an interesting excercise in choreography😁 P.S. Just found pic I took of the description Placard, I have no idea what it says...anyone here that can read French?
-
A few years ago at A few years ago at Blois I saw a petrol powered man carrying multicopter, I seem to remember it had 8 small petrol motors with servo driven throttles, I was sceptical and remain so...I wonder if he ever got the thing flying?...i'll try dig out a pic here you go 12 little petrol engines.....Blimey

We used to sometimes fit a foam ring called a Bib Mousse to our enduro Bikes, advantage was puncture proof, but you could never get the needed tyre deformation with them so grip suffered on rocks and roots and you can't just tweak the pressure for various conditions Also made the ride harsher and as you said no good for prolonged highway use as they overheated and broke down A gas filled tyre remains a hard to beat arrangement for most applications

For info, here is an exploded layout of a typical Denso motorcycle starter of the type Rotax seem to be using.
-
Exactly, but I've had enough of Facthunter and the mysterious pin that only he can see, Its like asking a Trump supporter to accept he didnt win the last US Election.🙄
-
Maybe someone else can step in and actually locate this pin that Facthunter insists exists in a picture in this thread?
-
It doesnt solely rely on the two m5 through bolts it also has a strap holding it to a shaped support, it's clearly shown in the Drawing that you seem to be having problems interpreting
-
No it doesnt I think you probably mean the exploded diagram showing installation of the upgraded starter and are confusing the the bolt that both holds the starter together and affixes it to the starter case with a pin protruding from the starter pinion, probably because the drawing is from an angle where it appears to do be in that position... .......its not a pin in the pinion hole.
-
it isn't. no starter discussed or pictured in this thread has a pin in the hole in the end of the pinion I've located and ordered a used Denso 228000-7460 starter as the appropriate model is no longer available new even from the motorcycle dealers who once used it, they all now supply Chinese copies. I'll report back to this thread when I find out if it is the direct replacement I believe it to be
-
You are over thinking it, the makers don't vary tooth profiles between similar starters for obvious reasons, there is even one very reputable Rotax engineer supplying an alternatively sourced part that may well be the one I've found. You've mentioned this pin before, can you point me to a photo showing this? To give one example of why this type of substitution isnt always the No No you imply, Rotax used to sell a Rotax Branded oil filter that was actually an easily available Mahle type but with Rotax written on it..this I would suggest is a far more flight critical part and substitution was in fact substitution of the same part. I suspect the same in the case of the starter, that it is a Denso unit already in production for other vehicles and is simply re-badged. This is the whole point of doing the research.

On the subject of lifting bodies, those of us of a certain age will remember the openiing sequence to Six Million Dollar Man that featured the Crash of a either a Northrop HL10 or M2-F2 (It remains an argued point and seems the fottage used is composits of the 2 types) HL10 Below https://en.wikipedia.org/wiki/Northrop_HL-10

Fairey nuff, But what evidence did you look at to determine rotation of starter? If you take a look at drawings of a Rotax Starter arrangement and videos showing work on the starter gear train and sprag they clearly show the direction of rotation as does the same information for the BMW F650.
-
Danny Check out this one.. Denso 228000-7460 (as used in Aprilia Tuano 1000 and others) I think this is the one, cw rotation all the dimensions match, .9KW Only question is does it have an internal oil seal on the output shaft and it will of course need longer fixings but I dont see that being much of a problem to source.
-
This is long winded..caution Its entirely possible I've made a mistake 1: The rotax 912 starter: looking from rear of engine and rear of starter....the crank rotates CCW...there is one idler gear between the starter and the ring gear on crank Therefore the starter motor rotates the same direction as the crank when both are viewed from rear...therefore Rotax starter motor turns CCW when viewed from its rear so CW when viewed from its front/nose 2: The BMW F650 Starter: Looking from the right hand side of the engine the crank turns CW...there are 2 idler/reduction gears between the starter and the crank so starter turns CCW when viewed from this side...BUT the starter when viewed from this side has its front/nose pointing towards you. So in conclusion if you look at both starters from the nose then the Rotax starter is CW and the BMW Starter is CCW and therefore not interchangeable If someone has time to double check all this I would greatly appreciate it

I would have thought cooling was an issue but apparently it had the same fan cooled Franklin engine as the Republic seabee and was actually better cooled during taxi and ground runs than its conventional counterparts in tractor installations

Is the wing partially detached at the rear?

Looks exactly like the Air Training Corps badge we all wore on our berets in the UK during 70's 80's. I dont know what the current badge looks like as they've renamed (dumbed down) the name of the organisation to "Air Cadets"
-
Ouch. I think its best to regard any forum as a gathering of people with some shared interest who can often offer advice and reccomendations but as we are all human its natural that opinions, humour and thread drift will occur. Regarding it as just an information service will I fear lead to dissappointment.
