Have you tried to apply full right-left rudder alternatively in a real Cessna?

I ask this because, I don't know in a Cessna, but e.g. in a B737, full rudder deflection _will_ flip the aircraft:

Hello, Marco.

 

That's actually a good question. I have not since I haven't flown a 172 since my avatar picture was taken and I don't feel like saying how long ago that was! I am 90% confident that the size of a 172 rudder would not have the same effect of that of the 737 or similar planes. However, in XPX, I am talking about a simple 10-20% deflection of the rudder and softly alternating between the pedals. In reality this should at most create a wagging of the plane's tail and maybe make your back-seat passengers a bit ill. In XPX this can create pretty fantastical positions for the plane that is quite comical.

 

The good news is I haven't noticed this with Carenado planes.

It used to be impossible to slip the aircraft in using the rudder as any speed at all caused the nose only to deviate slightly from straight into the slipstream, but now, you can actually crank the rudder so hard that you end up with a wingover effect into the rudder turn if you don't apply enough aileron. It's as if the slipstream is catching under the forward wing and lifting it while the trailing is losing lift. This does happen in real life, but it's not as pronounced as XP is making it. But at least I CAN slip into the tarmac now.

The default 172? Impressive. That's my one issue with Carenado's planes: they don't slip at all. The rudder won't move them enough to counter the ailerons but, of course, just because you can line it up doesn't mean it has the physics to act correctly. Which is too bad since slipping is a pretty important piece of flying.

That's my one issue with Carenado's planes: they don't slip at all.

 

I've never had a problem slipping the C182 in FSX. Is this an XPlane issue?

Hello,

 

I was referring to the XPlane planes with that statement, although the FSX planes of theirs I have tried don't do slips, either -- I could be wrong, though. I haven't flown Carenado's 185 but great to hear it does slip, especially in a bush plane.

 

Carenado's XPX Archer's rudder isn't even strong enough to keep the plane straight with counter ailerons so it's pointless to try but even with the little I tried, no vertical speed was gained. I haven't tried this out on the Seneca or Bonanza explicitly so I'm not sure if this is the case with those, too.

Great news today in 10.10 Beta 6 for the Baron 58:

http://wiki.x-plane....ne_10.10_Beta_6

 

Beech Baron 58 Fixes/Improvements:

• Wing landing lights added with independent control switches for left/right
  
• Revised Autopilot and annunciator panel so all modes work, including APPR
  
• ADF 1 added
  
• HSI now uses Nav 1, Nav2 and GPS
  
• Nav 2 VOR added
  
• Flight model improved
  
• Wing Ice light works
  
• Clock added to yoke
  
• Instrument night lighting fixed to work. No more lit instruments when power is off.
  
• Avionics fun doesn't come on when power is off.
  
• Dash annunciators improved and work properly
  
• Taxi light added to nose gear, aligned and working properly.
  

Is anybody seeing the artificial horizon go black at night in the Baron? It was working when I submitted it for the beta 6 update.....but I have developer files on my end and want to make sure I didn't mess something up on my developer copy only.

Looks fine here, with lights on and off

@Tom: the baron and the king air are just excellent, i appreciate the improvements you are bringing to the sim. side slipping works fine now, even for the c172.

 

but xpx has a huge hangar, it might be impossible to bring all of them to that level. eventually, you should mark some as 'premium' aircrafts and others as 'basic', so everybody knows what to expect. people here might start complaining about the more exotic ones as soon as they can't find anything missing on the prominet ones...

Same here!

 

The C90, the Baron 58 and the 172 are feeling great. This beta 6 runs so smooth in my rig that everything looks great :-)

 

Now if only Austin could finally address that problem with prop aircraft banking right when we reduce throttle from cruise settings.... ;-)

 

I smilled when I red a few days ago about the enhancements for beta6 FD... "Better performance on sideslips up to 90º and backwards flight...".. I'm loving Xplane, but I was tempted to write to Austin and say - ok, now please fix the forward flying too :-) Being bad, I know, and given that after fighting it for so many years (after v8) I finally decided to buy xplane10, it certainly is because I believe in it, and I really enjoyed the results I got from my xp10.10b6, but I think some basic aspects of the FD must really get addressed... For the time being I am using aileron trim, as once Austin suggested me...

Isn't that what single props are supposed to do? Every time you adjust the throttle, the torque on the engine is changing which will causes the aircraft to roll if your aileron trim isn't adusted.

Not with the intensity that xplane's prop exhibit, and a lot more in yaw than in bank, and, certainly not when the throttle is retarded and the airplane starts to bank right, unless it is built with cant, incidence to make it fly straight at cruise.. Problem is, all xplane props, unless they have counter-rotating props:

 

- Bank right when you retard the throttle (for clockwise rotating props)

- Bank left a lot more than they should, while exhibiting almost no yaw when at high power settings (i.e. during climb)

 

I can live with that - finally - because the good aspects of Xplane can compensate for this quirks...

What causes the yaw? Is it asymmetric prop wash over the rudder? Or does the engine somehow exhibit a torque effect about the yaw axis?

Both, although on the huge majority of GA aircraft the slipstream assymetricaly hitting the vertical fin/rudder contributes the most. Then, torque can cause roll, and thus roll-induced yaw too...

 

On a real, say, Robin DR-400, you'll notice the yaw, and the ball well deflected to the right and asking for right rudder all the way through your climb or whenever you use more power.

Hello Jcomm,

 

Do you have this exaggerated experience in add-on aircraft, too? This is part of the flight modeling I noticed in the default planes like the 172 but with nice add-ons, I haven't noticed this. In fact, where I just had to laugh with the 172 was when after takeoff, the plane just circled in a nice left-turn 360 right over the numbers in an endless loop.

 

This is why I mentioned earlier not to judge the sim on the built-in planes. I'm sure it just comes down to the smaller group at Laminair not having the time to tweak each plane like the add-on companies do.
