Thats a good point FlyingSquirrel lol :p

This has to be the worst heli paint job of all time! It looks like a flying tablecloth!! Look on the posative side with the table cloth you could play nought's & crosses while your waiting for your passengers. |
HEY TFS!
Now that's kicking a man laying, thank you very much! Me and Bjork have the same last name, and what do you know if she isn't my sister and the dress is my mothers handcraft? You kow Iceland is very small of a country. I think that her swandress is great and he who thinks otherwise shall have his head checked. May I point out to you that Bjork is a delicate little flower with an angels. And if you are going to express your self some more in a less positive way about our so very sophisticated taste for fashion, I will have to bring out my old viking ship, sail over, hunt you down and slap you around for a while! O yeah and maybe I'll bring you back the ugly Brit biddies my ancesters took from you on their way over to Iceland, we kept them safely in remote place for you! :} And this IKEA helicopter... ah well... Have to admit my curtains look better in this colour. |
This one has to be somewhere in the same "ugly" category..
Hypnotic R-44 http://img.photobucket.com/albums/v1...tainFlyers.jpg Just think about all the work painting the helicopters like that and they are even uglier. Sometimes simple is better ;) |
So in other words Heli-Ice, you're a redneck? Or should I say blueneck?:O
|
TFS.
You spotted me! :ugh: |
paint
You know, the wild scheme about two posts before this one is crazy, but those hyper circles certainly do seem to make the ship look a little less bulky. If we could somehow use that "busy" configuration in a better scheme we may be onto something.

Pretty paint schemes
I agonised over this myself but now await the arrival of my new Raven 2 in a boggo dark blue metallic with silver accents.
Why? I think you need to consider the next owner. What might look super cool to you could be the kiss of death when it comes to moving it on. Boring I know..... HP |
r44 waddle
flying a r44 raven today at 115kt with a serious waddle, is this normal. thought the tail was about to fail. maybe i've been drinking to much never experienced this in a astro
|
Like the post above I can answer this in relation to the Enstrom. when in the cruise at about 85 in the Enstrom it develops a similar waddle with a frequency of about 1.5 Hz. It happens when flying in perfect trim and resonates so gradually gets more severe. The Engineer told me it was some sort of interaction between the TR and the vertical stabiliser. It disappears if the aircraft is flown ever so slightly out of trim. It doesn't matter which way. Just a hint of pedal. Make sure its not enough to cause extreme flapping problems in a Robbie though!!
Altering the speed will also damp it out so it would appear to be a resonance problem. Edit: I just remembered what he said. It went something like this. the TR acts like a vertical fin when in forward flight, the angle of which is determined by the pitch on the blades. The waddle happens when the 2 'fins' (TR and real fin) are at slight, critical, different angles to the airflow. Vary the angle of one and the resonance stops. |
I have noticed a similar sensation on the jetranger if you push the nose over on decent. It feels a bit unstable once above about 120kts. I have heard other pilots comment on this as well in the 206. It is easily fixed with pedal input on the 206.
|
A governor that is pulsing can give this waddle too. (Nice word waddle ins't it?) Try switching off the governor in stable, straight and level flight and see if it still occurs. If not, you've found the problem.
A dodgey magneto can have the same effect. I'm sure your engineers favourite job is stripping and re-assembling a magneto :E |
Helo 44
What happened before/after failure - since close to new and during start up the starter motor would occaisonally fail to engage with the ring gear. this made a sound like high pitched whizz... Also, on the Raven II people tend to hit the start button - engine fires - stops. . then they hit the start button again before the engine and starter have come to rest. . . this also mashes the ring gear (with an elongated shape) Float Test R44 waddles in very calm conditions when in balance, a little left/right pedal sorts it out . . I belive the flat back of the engine/fan cowl is the cause. . :8 |
I saw on the BBC news this morning one of the reporters flying over london in a R44 or 22, filming the lack of traffic after yesterdays attack. I had to smile as I could see the pilot working hard to trying to keep it stable and in the hover... I did like his military style flying suit complete with gold bars, bet he parks the Robbo "round the back" and has an Agusta key ring :E

.... a recent victim of urban graffitti tagging perhaps ? ....;)
h-r:) |
Looking at Aesir's picture, it must have taken one hell of a pilot to park that fixed wing in the hangar!
:ok: |
Hehe.. Lightning_Boy yeah didnīt notice that! Looks like a Bucker Jungmeister donīt it.

Or thomasthetankengine, after that heaving landing, chess, while waiting for the fire brigade !
