POSKY 747 Problem...

[Ashar]

Okay, I got this beautiful paint for the POSKY 747 complete with model and all...When I move the aircraft under it's own power, the rudder pulsates as though the wind is blowing...Then when the aircraft moves, the rudder looks very strange and the aircraft's nose gear pulsates...Also, if I try to turn left, the wheels turn right...It's really weird...LOL...I'm guessing it might be something to do with contact points or something...Can someone help?

I had the same problem with a Cathay Pacific POSKY 747 Ash,I just uninstalled it and installed it again and it worked fine,have you tried doing that?

Nope...Might give that a try...Thanks Dom

Ashar, and fellow simmers..

I just downloaded 744 Posky as well..
Would appreciate if you can share your experience...especially with its descend performance

Thanx.

Hello, playmates - I'm back from my travels in the US.

Ashar, the rudder and nosewheel vibrate like that because of the yaw damper. Some models are just prone to it - the 737 Experience (very close to my heart!) tends to do the same thing. What I do is to turn the YD on just as I'm moving onto the runway. Less 'by-the-book' maybe, but at least it stops the wobble.

Aritrixa, I haven't downloaded the V4 Posky 744 yet, but I will later today. Hopefully they've done something about the flight dynamics, which were, er, less than optimal on the V3. I'll get back on the descent performance.

Thanks for the tip Micro! I'll give it a go...I didn't know the v4 were out...Having a look at them as we speak...Hopefully, it should be very nice

Hey Ash,

maybe try take the .cfg file from another working POSKY 747? Should fix it.
EDIT I see you've sorted it.  ;)

Descending is hard in posky 744 and 742 just add a little throttle before touchdown and your set.

I had no problem with the descents...Let the autopilot handle things...It makes life much easier...I disengage autopilot around 10 miles from the airport...I like to hand fly all my approaches

Exactly. I think its just if you have full flaps too earlier then your speed is reduced too much and you need to pull in a notch or two of flaps and give it a little throttle before you stall.

I'd hoped that the flight dynamics would have been improved in V4, with the addition of another FD person at Posky, but things don't seem to have changed much. They still have that unusual notion of putting the reference datum almost 100 feet forward of the reference point, and the C of G more than 100 feet behind it! (They are usually at zero for both - waterllne, centreline, quarter wing chord etc.) Whether this is a device to stop tinkering I don't know, but the result is that even though the FD seems to have most of the right numbers for a 747, that doesn't stop the nose wheel collapsing on the tarmac as soon as I load it up. (Anybody else notice this?) I've had to adjust the load locations to help with the balance, so that it doesn't do it, but the balance is very sensitive indeed. It's not like that on a real jumbo! Also, anybody noticed that on final approach at full flaps around 145 knots, it has a nose-down attitude? Looks like too much lift and not enough drag on the flaps, so I had to adjust those too. (Oh, and adjusting the too-high nose attitude in cruise.)

Or is it just me?

I do get that sinking nose gear as well...As for approach...For some reason, yesterday mine kept pulling up...Needless to say, I stalled and crashed...I was holding the autopilot...Was very strange...Oh and the autopilot was holding 160 knots with full flaps close to around 6 miles from the airport...I tend to let the autopilot handle things for 747 until the last moment...And because I was watching a TV show

Quick update - Posky has posted updated FDEs for the 747s on their website - seems to have cured the nose gear problem.

Thanks...
Would give it another try..

big warning:
Dont forget the XML gauges (see readme) or the wings wont flex and the maingear acts weird
