Yep the Real Air sf260 is great!

I agree with geofa on this, if you try and maintain alt in a slip of course you will lose airspeed because of the added drag. The whole purpose of a slip is to descend without picking up speed much like the flaps are meant to do on a normal approach. As far as slowing to Vs in a slip i have also seen CFIs do this (i have never had a reason to attempt this on my own) but as far as spin goes it is a "skid"(opposite of a slip) that will get you in trouble fast but either can lead to a spin.PS just my two cents RealAIR make cherry adonn A/C and i would love to one day see them or something comparable in XPX

Yeah-but I would be pegging the airspeed at approach speed. If the airspeed indicator is decreasing while in a cross controlled situation you are asking for trouble and it can happen fast...but actually thinking about what you just said-you are increasing your descent rate while maintaining airspeed by adding increased drag-not going slower..

If your on short final and you are at stall speed and you decide to slip, maybe your asking for it. But if your high up and you want to loose allot of altitude and not increase your speed then you can use a fwd slip.If you initiate a slip without pushing the nose down you should loose about 5 or 10 knots. Correct me if I am wrong.So I just loaded the f33A and I trimmed it for a 500 FPM descent, when I initiate a fwd slip it does nothing besides yaw. It doesn't slow down and doesn't loose anymore altitude then what it was trimmed for.If try it in the Carenado 172 it does the same thing(nothing). If I do a fwd slip in another payware AC it does what fwd slip or slip is suppose to do.Try slipping in a 10 knot crosswind and maintain your heading, you can't.The flight dynamic are off !

The RealAir Duke is a perfect example of what a fwd slip will do !

Thats exactly what I was saying in all of my posts. The Carenado plane won't loose anymore altitude and it won't bleed off any speed in a slip.

Just tried for my self. I did lose about 4kts of ground speed according to the GNS at cruise settings, I was expecting a little more. At some point thrust and drag would equal and you should not lose anymore speed when holding lvl flight in the slip, I have never flown a real bonanza so i will have to digress on how accurate the model is. Still imo one of the best for XPX

Output total drag to screen in the sim. Check if there is a drag rise when in the slip(while maintaining airspeed..)M

There's a general rudder yaw/roll problem with the F33 in x-plane. If you apply full rudder the yaw response seems to be definitely too weak but the yaw induced roll is overdone.( this yaw/roll interaction is more suitable for a swept wing jet)With full rudder there's almost as much roll as yaw.You can't even fly a 15kts crosswind approach in crab and take the drift out during the flare because the rudder is too weak.Although the RealAir Duke and the SF260 do slip nicely they are way way too stable in yaw. AFAIR this was necessary back in the old fs9 days in order to be able to force the planes into a kind of spin. Put the Decathlon etc..into a slip, neutralize the rudder and see how long it takes for the nose to swing back.That excessive yaw stability is also the reason why the Duke doesn't have a realistic engine out behaviour and the Decathlon can't snap or do a hammerhead.

Yep-no flight model on any sim is close to perfect..yet...The maximum crosswind component for most Bo's is 17 knts so 15 is getting pretty close...The video I submitted above does show a forward slip being done-which was the question of the original post however......and yes the yaw induced roll is overdone-but at least there is yaw!...and I would not hold the Duchess however nice it is to be perfect either...When the Carenado F33 came out for fs there were similar complaints with the mantra of Carenado fm's being bad (and some of them have been less than stellar). However one of the one's that got me was someone complaining they could barely get off of Concrete, Washington's runway. I remarked that could be a challenge and was told no-it is a bad fm. Well a guy , who is a simmer and Bo pilot posted a video later that was very compelling of him taking off rw from Concrete in a bo and barely making above the trees at the end-it was a sobering experience for him and a scary experience...I wish the video was still out there.In any case-I don't find the slips that far off and there are others which show it isn't a Cessna. For instance, at cruise put it into a gentle 500 ft. per minute descent-where does the airspeed go? You won't find that in a Cessna. imho it is a little slow to react-but react it does.With that in mind, I hope talented people like bstolle will get involved with xplane and make the fm's even better-but I probably would not be interested in xplane if it was not for this fine aircraft!

Does the F33 use some kind of artificial stability system?M

Artificial in that it overcomes what appears to be negative stability issues in xplane by cheating? I would think only the designer would be able to answer that one..

I would think only the designer would be able to answer that one..

That depends. Try this;- Start PlaneMaker- Open the aircraft- In the menu line goto EXPERT/ARTIFICIAL STABILITY, goto the "Art Stab" tab- If there are any entries there (other than 0) it uses artificial stability (or take a screenshot for us)M

Yes there are entries...I don't know if I can post a shot as it might be proprietary?

The fact that it's there speaks volumes.I might get reamed by some people for saying this, but using the artificial stability option is a cheat.

Who cares if it gets the job done....and I'm still waiting on ahem a over roll fix on a certain aircraft, roll rate way too fast. :-)

Not quite Goran, e.g. a yaw damper pr definition IS artificial stability :smile:Besides, who cares how an aircraft looks in planemaker as long as it performs like itshould in the sim.But like I said recently, if you don't know what you are doing, playing artificial stabilitycan open a can of wormsM
