For a start, I don't know, I wozn't there and I havn't seen the mess.But the truth bout that will out, one way or the other.Wot I'm very dissapointed bout is the way he shifted all fault to the builder and tell blaitent lyes on a publick forum. That I do KNOW and that I don't like.As you so rightly point out, you can't know the cause of the crash.Paul asserts that it's the rudder cable swage failing. How exactly is that "shifting blame?".A bloke I worked with years ago used to say and live by the motto "BuII**** Baffles Brains".Your brain is being baffled.Saying something doesn't make it so.

Well,Today is the first I've bothered to have a look at the Rotorcraft forum.There are in flight photographs being taken from an in-flight machine... in one I think I can see the joystick without a hand on it.Given that it is a new machine in test flight, is this a good idea? Would it be wise to divert ones attentions from flying a new machine in such a way?Nick.

Mr Bird,Seeing as you own a Rotax 912 and have many hours on one, and I don't, what does this:Image Insert:

Was there some mention of the performance being sluggish in one of the posts?I wonder why...

Do you want to say, that he not only crashed the gyro, but also screwed up the enginebefore flying without oil pressure ????I checked the original pic posted in US forum and it really shows that...How nice of him....http://www.rotaryforum.com/forum/att...achmentid=8568

Mr Kay,I wouldn't know, I fly a soob, they usually have 60 ~ 80 psi at 3800 revs, or at least mine does. I don't know about these rotax engines, allegedly the two strokes have no oil pressure, why should a 912 have any, aren't they two strokes as well?Do you have a 912? what should the CHT be at these revs?Nick.

Nick I think 912's and 914's are four strokes, Birdy's always saying he prefers the '4 bangers'. So if it is a four stroke, then it should have oil pressure, shouldn't it???Mitch.www.thebutterflyllc.com

It certainly is a 4-stroke.We are flying it on some UL planes (Tecnam Golf, 3XTrim, Remos).They are very sensitive against oil pressure. Part of the cooling is by oil.

Greg,I thought his reference was to 4 cylinder.If it is a 4 stroke this could have some implications.

I'm guilty of having flown without engine gauges etc etc, for a variety of reasons over the years. Sometimes they were there, but not connected etc etc. Feelin the air is the way also, forgit bowt airspeed indicator.[

Nick (and anyone else),If it was a 912, 912s or 914, it is a 4 cyl 4 stroke with the 914 being a turbo. (water and oil cooled)The 2 strokes are -(1 cyl) aircooled 277, 377 (2 cyl) aircooled 447, 503, watercooled 532, 582 and 618(corrections welcome) telfFlying - The knack lies in learning how to throw yourself at the ground and miss.

Same picture: Zero CHT. Hmm.... Almost no oil pressure, high revs, and a stone cold engine. Ahhh! Contradiction!!!!Maybe it's a gauge problem!!!!Maybe there isn't any need for ritual disembowelment as well as hanging, drawing and quartering...

Most likely a gauge problem Nick, I dont have a 912 but I'm sure I have seen oil pressure gauges in them. I would be looking at the gauge senders and going from there.Engine without any oil pressure and or showing no temp, will not last for very long !! and will most certainly sound very diferent from a healthy 912, the Suby gets quite a rasping type of sound to it with no oil press and the temp gauge pegged to the stop and at cruisin revs.You never know how far you can go, till you get there !
