Hey !! Really nice dude, a good brother of our slow PC-6 ;-) Wish you luck in development, will look closely to it ! Cheers, Valentin

Thanks ! We hope to deliver new screens soon, but I know what is the most interesting and it's not renders... but in-game shots ! Unfortunately, we're a bit far from it.. One day, one day !

Yeah LAdamson, your comments about mixture etc on both sims are so true.. unfortunately. The overall braking effect of a prop is the result of several factors, some are too maths for me but, for us pilot, the simple clue we have to remember is : the lower the low pitch stop is, the higher the brake effect... On general aviation ACFT such SR22 and so , the low pitch stop ( mechanical ) should stand around +12° positive pitch. While it may create some significant braking effect at cruise airspeed when you fully retard throttle, it's nothing compared to what more advanced turboprop can do ( once again, I take the PC-6, which I know very well, for example ). So, the low pitch stops IN FLIGHT ( because if reverse is available, low pitch stops on ground are more likely to stand around -11° ... ) and the blade chord, as well as its airfoil of course and obviously, the relative wind passing through the prop ( so determining it's AoA ) are such factors that determine the braking effect. Finally, to answer I can tell you that in X-Plane, you can slow down EVEN FASTER than what you described, it's just a matter of having good blade chords, min pitch ( low pitch stops ) as well as airfoil. All of this is easily customizable in Plane Maker. The last factor, and by the way, the most problematic for my work on Plane Maker and the PC-6, is that low pitch stops request low airspeed ( so, not much windmilling effect ) to be reached, cause of ther ( overspeed ) governor action. You can't reach PLPS ( Primary Low Pitch Stops ) just by retarding throttle, or PCL while in high airspeed conditions ( cruise, descent... ) Hopefully, I will find the solution for my problem. Anyway, many interesting things to exchange here, I'm pleased to see there are knowledgeable people there, flying in X-Plane ;-) Have a nice day dudes, Valentin

Do you know what will come next ? I would LOVE : - TBM850 - Kind Air B200 or C90B - Any PT6 powered turboprop ;-) I'm just in love with that kind of turboprop, like a big breathe after the long time learning and management of good old radial engines, a la accusim ( B-17, P-47 etc... )

Mm ok nice if you finally managed this ;-) ! Just another thing to know : After flying X-Plane since early V8, I always noticed it has a tendency to be very " clean " and " gliding " in many aspects. for example, helicopters in autorotation have overall less descent rate and bigger RPM rise compared to the real thing, and a plane in X-Plane while in descent gain speed quicker than in real life ( I compare this with a C152 that I know for example ). Globally, I would add a bit more drag to virtually anything in X-Plane to be more consistant but.. that's the way it is ! Maybe all that is because the flight physics are really precise and constant calcul-based.. making a very " living " simulator. Back at my MSFS days, I didn't noticed that the slightest of my input ( prop RPM, mixture, Manifold Pressure etc... ) change affected the sim much.. Anyway, tell us the final result ! Valentin

Hi Jason, If your ACFT is one equipped with constant speed propeller, you can lower the minimum pitch value ( low pitch stops ) reached when the Prop Lever is full forward, Throttle full retarded and the slipstream isn't strong enough to continue windmilling the propeller ( low airspeed, like in final approach ) When that kind of prop is in low pitch angle region, it can create a serious ammount of drag ( example, some planes like the PC-6 can reach impressive dive rates by throwing the prop in the Bêta range, in other words, very low pitch setting, near of flat ( 0° ) pitch. Try it with values like between +8° and +12° and adjust as necessary, I'm sure you'll reach what you want. Of course, if this is a fixed pitch one, all I said is useless.. Good luck, Valentin

It really looks to be a great aircraft .Watched excellent Javier start up tutorial on youtube ! I'll buy it as soon as it is on the org or Aerosoft.

Hello everyone ! While a thread for our airplane is already opened on another forum for a while, I think it's also good that it's shown here, where there is a growth in X-Plane simmers since X-Plane 10 is out. This project started in March of last year, and is carried by MR3D, the nice scenery developer of HMS Jackdaw, EGOD and the really great Mitsubish A6M2 Zero japanese fighter ( http://hosting.x-pla...bsite/zero.html), and me. The tasks are divided like this : MR3D : - 3D model of the plane and cockpit - Texturing, animating Hueyman : - 3D model of the turbine and the prop - Flight model and systems - Sounds recording We should both work on sounds, planning to use the excellent Dream Engine from the Brazilian great helicopter developer " conex " Now, let's know a bit more about this very particular plane : The Pilatus PC-6 is a swiss airplane, made by Pilatus Aircraft. The enterprise is located in Stans, near the Pilatus mountain in Switzerland. The first model, flew on 4th May of 1959, powered by a Lycoming GSO-480-B1A6, a 340 HP piston engine. It was designed to be a light, solid and robust aircraft, a STOL one ( Short Take Off and Landing ) The result exceed Pilatus's expectations, and now in 2012, the PC-6 remain the world's leading turboprop in the STOL category. The latest versions, /B2-H4 are powered by the famous Pratt & Whitney PT6-A27 or -A34 Free Turbine Offering 680 and 750 SHP allowing it to bring 9 or 10 skydivers up to 4000 m ( 13000 Ft - FL 130 ) in less than 20 min under International Standard Atmospheric (ISA) conditions. This powerful powerplant, coupled with a Hartzell HC-D4N-3P ( fully featherable four-blade aluminum prop, with reverse thrust abilities ) permit very short landing distance ( 315 meters - 1030 Ft ). It's aslo able to dive from 4000 m ( 13000 Ft ) to runway in less than 2 minutes, diving straight from the sky without coming near VNE, and this is thanks to it's very draggy geometry, and it's propeller spinning in Bêta mode ( not in reverse as reversed propwash would disturb the air slipstream over control surfaces and making plane uncontrollable ) a mode which put the propeller blade picth near 0° pitch ( no positive nor negative thrust ) so it acts like a big disc shaped airbrake Many versions has been built, using different Pratt & Whitney PT6A, or even older Turbomeca Astazou ones... The PC-6 saw action in Laos and near Cambodian border during Vietnam War ( you MUST watch " Air America " movie with Mel Gibson and Robert Downey Jr. ), and is still used today, in remote areas, where helicopters are out of range, or don't have it's one ton fret potential to carry sufficient stuff. Our choice has been set on this ACFT for some reasons : 1 ) There aren't enough aircrafts of that category in good quality for X-Plane, I'm only aware of both incoming Soul Made Simulation's Beaver and Dan Klaue Quest Kodiak. 2 ) I personally love this aircraft, I see it almost every weekends, as my mother is doing skydiving in this one. This means I have access to real ACFT datas, PoH, ref speeds... and also pilot feedback and mechanics feedback. 3 ) Because of above statement, I'll be able to record high quality sounds ( via Zoom H4N ), directly on the real aircraft, producing one of the most immersive sound experience in X-Plane, and not using default X-Plane crappy sound system. 4 ) With the flexibility of our lovely sim, we guess it would be possible to do some exclusive features, which are also done in the real life by this - so special - plane : Skydivers drop, fret transport in high altitude fields like Lukla, humanitarian mission on damaged airfields in Africa etc.. 5 ) Because it's a relative simple ACFT, without many avionics or systems, I think we could reproduce it as real as possible, to offer our customers both a realistic experience, with all procedures and checklists followed, and a non negligible fun factor. If all goes well this year, for both of us, we hope to see this plane released by the end of Summer. Here are some WiPs shots. And don't forget to check my little blog, ask questions and drop comments, you'll be welcome ;-) http://hueyman.overblog.com/

Hey Phantom88, thanks for your interest ! I'll eventually start a new thread here, but the main one is still on the org : http://forums.x-plane.org/index.php?showtopic=58037 There is also my little blog : http://hueyman.overblog.com/ And just to clarify, the PT-6 Porter don't exist.. there are the Pilatus PC-6, and it's associated, very famous powerplant, the P&W Canada PT6 Turbine ;-) Cheers and happy new year everyone !

Dunno for the Valkyrie but for his Huey .. http://forums.x-plane.org/index.php?showtopic=37508 and Bell 47 http://forums.x-plane.org/index.php?showtopic=49960

It isn't for a King Air, but on the PC-6. PT-6 engines are so reliable they are used in so many ACFT.. I think those engines pushed the propeller to it's maximum possibilities.. alpha range, beta range, reverse and feathers really allow the plane that carry them to do many things a fixed pitch prop equipped plane can't do...

I'm myself very interesting in the modelling of the PT6 A-34.. By hetfield81 at 2012-06-14 By hetfield81 at 2012-06-14

Hello dude, It was Propsman who started that... since 2009, he seems very busy, involbed in XP10, and no news on his Bell 47, Huey and Valkyrie.. unfortunately... Hope to see him soon ;-)
