  1. Thank you Peter The missing sub menu is the pattern selection window. The Addons/CumulusX!/SmartTow option does show. It did work at one point. There was no change in the update of P3D in between. Simconnect hasn't changed either, but it worth an enquiry. Thanks, Harry
  2. Hi there CumulusX users and developers I'm a paid registered user of CumulusX and the help about menu says I have licence no. 64. CumulusX works very well but not smart tow. It did work initially, but broke at some point. ****I fully understand that P3D is not supported, but thought I would ask anyway just in case.**** Here is what I did to try and repair it: CumulusX registered and licenced Reinstalled CumulusX from a clean registry and reapplied licence.bin and txt file to activate CumulusX features CumulusX DLL is true. Here is what works: Default Tow works - Maule Addon menu in P3D calls up the main CumulusX panel and debug. Blue thermal option works. Ridge and thermal lift work. Clouds work. Birds working (proves licence) P3D configuration file has correct entries for towplane (manually added) to [SIM] section of Prepar3D.cfg Have put in dummy FSX.cfg file in all relevant locations in case CumulusX is looking for an FSX configuration installation (which there isn't). CumulusX does NOT warn that it is waiting to write towplane config to FSX.cfg. Can select towplane and options like flap number in CumulusX when the sim is not running. Here is the problem: Can't select towplane pattern - the sub menu doesn't appear in P3D. The selection I make for towplane in CumulusX does write to the registry. CumulusX doesn't seem to know that it needs to write towplane data to the P3D version of the config file. Conclusion: So the tow I get is straight out and I think it is just normal P3D towplane working (Maule). Why smart tow worked at one point even without a config file entry in [SIM] is a mystery. Thanks if you can help. Cheers Harry PS) By the way, a UKVGA member is trying to get P3D 64 bit working with CumulusX and it does, but it is tricky. As yet, without support for P3D 64 bit, the virtual glider community is slowly going backward not forward. There is still not a single simulator other than Condor that models a thermal with an associated cloud.
  3. Yes please Peter I will go whatever platform you think is best. I'm hoping that Prepare3D will release with a complete bug fix of FSX and basic performance improvements for latter day hardware. Ben, I share your enthusiasm for CumulusX! Enjoy
  4. Thanks for that B21 and Jcomm. Check out this post with respect to ballast, the wandering albatross bird and climate change! The post is a bit off topic but if you love gliding of all kinds it's a must read. Basically the observation is that as the ocean winds increase over the last few decades, the wandering albatross is able to reach more successful fishing grounds with the prevailing wind which makes them fatter and heavier which increases their wing loading but helps them soar better because the ballast increases their flight performance in the changing conditions. "The researchers found that westerly winds in the Southern Ocean have increased, on average, by 15 percent over the past few decades. Both female and male flight speeds got a boost as a result, with females alone traveling about 311 miles per day in 1990, but about 435 miles per day as of 2010" http://news.discover...eds-120112.html Enjoy
  5. Jcomm having been a long time DiscusX flyer in CumulusX, if you make the move to DiscusK thermalling is more challenging than the DiscusX. I'm only starting to get the hang of the DiscusK. I think the trick is that you have to turn a bit faster in thermals especially if you are not circling in the precise core of the thermal. If you set CumulusX to 100% turbulence effects, what happens is that the DiscusK seems to get thrown out of the thermal much more than the DiscusX if you are flying too slow. The inboard wing is in the lift but the outboard wing is not. In this case it seems that the natural tendancy is to try and push the inboard wing back down against the rising air but if you are flying too slow it seems to induce a stall of some kind and the glider is thrown out of the thermal even worse. So now I try to keep the speed up a bit during thermal turning and not force the glider to do anything it does not want to do. This typically means I seem to be turning the DiscusK at 55-60knots when I could turn the DiscusX a lot slower without being thrown out of the thermal as much. In some respects it might be that the DiscusK is setup with less stability than the DiscusX for extra performance, but making it a more difficult glider to master. Turning faster in thermals means you can bank tighter and stay in the lift. Once you have cored the thermal you are turning faster and have sacrificed some climb rate for the sake of staying out of the turbulence at the edges of the thermal. Flying the DiscusK is a real challenge! It might also help to reduce the sensitivity of the aileron axis a bit. What I found happening is that I would start to oscillate my bank angle trying to core the thermal as I flew too slow then pushed the inboard wing down then to have it pushed back up then me pushing it down again and so the bank angle was not steady. Once the glider is centered in the thermal only a bit of opposite aileron might be needed, but it's the process of trying to get into the lift that is the tricky bit! I don't think it is the sensitivity of my joystick but probably flying style bad habits from the DiscusX. The problems of flying in a thermal also depend on the thermals strength. I am flying between 12pm-2pm in the heat of the Australian summer and the thermals are strong combined with a moderate prevailing wind as well. I'm also experimenting with water ballast in the DiscusK and whether the simulation of ballast makes any sense in FSX/CumulusX. In real life it is a big factor because it helps with settling the glider down in turbulence as well as penetration into the wind and overall efficiency. It sure is fun to see the water streaming out of the back of the glider in the preparations for landing. Enjoy!
  6. This could well be old information for many, but if there are any reasonably experienced CumulusX pilots that know the basics of gliding pretty well but want an extra challenge for thermalling as well as aerobatics, I highly recommend the Discus-K model from Aerosoft. I've been flying the Discus-X model for a long while and assumed that the two were essentially identical but for some cosmetics, but for some reason I don't quite understand I think I was wrong. The Discus-K simulation has taken the enjoyment factor up another notch for me, as well as the difficulty. It is truly a nimble and responsive glider, beautiful to fly and is a nice test of gliding simulation skills. I really love the lack of electronic instruments leaving the experience down to the raw basics of flying itself. The part that surprised me is that the Discus-K simulation actually noticeably reduces the load on the CPU and frame rates (a small effect but noticeable), and increases the thrill at the same time. Just remember to un-comment the water ballast code in the aircraft.cfg file because the developers decided to disable the code by default I think because the K was primarily intended for aerobatics. However it is also a beautiful thermal ship as well! Enjoy Harry
  7. If you want a little extra with the CumulusX smart tow plane, add 10% wake turbulence simulation from AS2012 and have some fun! I think it is probably not very realistic but it does add plenty of incentive to stay out of the tow-planes wake that's for sure! Just don't increase it much beyond 10% or the tow rope will snap! Cheers Harry
  8. Hi Peter and Beta Testers For CumulusX I wish you a happy and peaceful Christmas 2011! Have a drink on me. Without a shadow of a doubt CumulusX has been the most enjoyable software I have ever used on a PC. It is infinitely interesting especially when combined with real weather and terrain. I have fired it up again for the last month after my exams and am flying simulated cross country on the east coast of Australia. Wave-lift would be a dream but it sounds like a really hard computer science problem. I hope it is an enjoyable challenge! My processor is an i7-2600 3.4GHz if that gives any guide to how much computer power is readily available these days. Thank you sincerely! Harry
  9. Thanks Peter! For all the support you have given for CumulusX. I wish for you that one day you can chop off the nose of your glider and install one of these with an electric fuel cell rather than batteries : http://www.front-ele...r.com/index.php If I could ask, where are all the CumulusX pilots hanging out in multiplayer these days? What type of multiplayer is most popular that required this update? EDIT: Thanks to Bulau, my multiplayer questions have now been answered. Cheers Harry
  10. The wave seems to move forward with altitude. Cheers
  11. Yeah thanks. The bit I'm amazed at is that the wave height oscillates with altitude. I thought that it would set up wave's but that each wave would be x-shape, y distance apart, and taper off in height gradually by z-amount. This is a difficult problem for FSX when you see what is actually going on. Cheers
  12. Yeah beautiful shot awe inspiring paper as well. What to do in terms of pre-compute/real time calculation with two mountains next to each other in FSX Cheers
  13. Eh Peter The graphics link to your picture is broken at this point. Wonderful paper! Getting the efficiency of the algorithm up is a big challenge. Here are other resources for interested enthusiasts of wave lift: B21's post on wave lift June last year: http://www.forum.aer...showtopic=35874 Great real world practical information on wave lift flying: http://www.canberrag...waveFlying.html Cheers
  14. Thanks anyway and best wishes for the new year 2011 Peter and fingers crossed that you can achieve a wave lift algorithm this year! Here is a link to the Canberra Gliding Club who fly the real thing! http://www.canberrag...waveFlying.html Cheers Harry
  15. Hi there Was flying in the simulator on a typically nice cumulo cloud morning as depicted by CumulusX/ASE/REX2. The CumulusX simulation will allow cumulo clouds to form into bands or lines of cumulus clouds in certain situations and that phenomonen was particular strong that morning. It got me thinking.... I was flying the glider parallel along a distinct band of cumulo that had formed a line allowing me to make some decent progress in distance at no cost. The glider's altitude was greater than the cloud base flying adjacent to the clouds themselves. Fly too close and you hit the turbulent sink. Fly into the cloud line and you get turbulence and cannot see left from right. But if you fly parallel to the cumulo line just outside of the turbulence area ahead of the line, you hit an area of very slight and smooth lift where the glider's normal ~1.7ft/sec sink rate is cancelled out. I do not know why the simulation does this, but try it for yourself and see. The experience truly felt something like what it must be to fly ahead of a line of rolling clouds! The interesting bit is that the shape of the CumulusX clouds when they sit in a line almost look like a roll cloud already! (see attached image). If the simulation already creates a line of subtle lift parallel to the band of clouds, all that has to happen in CumulusX to make the band of cumulo "roll", is to put the clouds closer together so that there are no gaps , then spawn new cumulo objects ahead of the band and delete the old cumulus objects at the rear of the band , and the cloud line would essentially appear to "roll" forward in a line . I realise that the degree of the updraft ahead of the cloud would be wrong relative to reality, and also the downdraft at the rear of the line would be wrong too, but it's an idea anyway. Here in Aus we have the amazing Morning Glory Phenomenon (see attached). I'd say this phenomenon could be implemented in CumulusX but I totally appreciate that it is not as easy as I think, that it takes a lot more time than I think, and that it will possibly never be simulated because the phenomenon is too rare in the real world to bother to simulate. Whatever. Thought I would throw my two cents worth in. Cheers Harry
