DO NOT USE THESE ONLINE PLEASE Hawker posted beta 2 of his Tiffie FM on the OPP forum, and I posted beta 3 of my 190A, spit V and Spit IX based on Koppers new information. beta3
- tested the Spit V for climb, top speed and ceiling they seem to match
- Fixed up low speed acceleration so now AI can take off with spit V on full tanks with a hill at the end of the runway !
- added drag to get 190A top speeds in line, tested for top speed and climb rate seems to match, ceiling too high.
Climb rates checked on full tanks. Greg / Tailslide

Thanks, guys. I will test these tonight. I am very impressed with the latest FM builds and finally the potential of SDOE seems to be materialising. I have been flying quite a bit off-line recently and have been having a lot of fun against the AI. The Bf109g-6 is a dream to fly, a real challenging against the Spit IX but I can usual win by using good energy tactics. I think against a human opponent it would be far harder, unless you entered an engagement with a height advantage.The Spits are both fun to fly but the V is only really effective if you can sucker your opponent into a turn fight - luckily the AI will usually oblige. The IX on the other hand is a capable opponent for the Fw190 and has the edge over the Bf109g-6. The Tiffie is getting there - but it ain't no dogfighter. However, if used in the interceptor role, its high low altitude speed and stability as a gun platform will be in its favour. Additionally if you get in trouble it should be able to out pace the opposition. The Mustang is now a far more attractive proposition, while the Dora is being worked on and I look forward to seeing what Zur can do with her. The Lightening still seems a little too potent. It was a surprisingly manoeuvrable plane but still seems a little uber in all respects. I was dogfighting one in a Dora a couple of nights ago and was chasing it down as it tried to extend in the horizontal. The P-38 turned hard ahead of me made a pass head on and then hooked up behind me. In the mean time, I continued to fly straight and level, yet I had a P-38 which had executed 2 successive 180 degree break turns sitting on my tail with heaps of energy. It still doesn't seem to bleed off energy as it should. In support of your observations about the density of the air, I still feel that the drag applied to these aircraft by the game engine is too low. I spent 5 minutes last night chasing a P-38 with no props across the channel at 300mph! And he wasn't slowing down. On a more positive note the ground handling (a issue we have debated ad nausiam) is now close to what I feel is sensible. I have been able to pull off some nice 3 point landings, and take-offs have to be executed with careful precision but are possible with out dragging a wing. Congratulations guys you have done a great job. Just don't stop now. [This message has been edited by Yardstick (edited 11-25-1999).] IP: Logged |

The SpitV, IX, 190A, and tiffie all had drag increased on them. I'm pretty sure at least part of the drag problem was the windscreen of the spit and the nose of the 190 did not add a lot of drag like they did in real life. The p51 did not have drag increased but it was a famously drag free plane so I'm hoping this will make shallow dives in the mustang a good tactic. Agreed about the p38, Zurawski may have that puppy in shape for the next plane pack. TS

Tail i have beta 3 of tiffie available now,but i need u to do some majic with the rudder i couldnt find the property u metioned so i tried another.Didnt seem to work so i left it alone at its 5.2 state.IP: Logged |

Tailslide,Are you changing cm,cl,cd in airfoil data?
Are you using Etienne´s tools ? Thanks in advance. nuum

This is a question for MH and I hope to help with it to all of you wonderful FS "workers":
I wave a weak understanding about aerodynamics and drag plots in NACA profile data; but I think that the parabolic plot that NACA gives for a PROFILE only considers the increase due to the form and interference drag; In a real finite wing, there is still a induced drag increase to be considered, that is in proportion with the square of lift produced, that is to the increase of the Angle of attack.
I´ve seen in the Openplane spec that data for the chord, span and Oswald´efficiency factor are required to prepare a profile. All of them are necessary to compute the induced drag; So, when you include drag profile data in your models, Openplane computates it to add the induced drag? Could this be a reason for the lack of drag into the game? Am I right with my thoughts about drags in profiles and in wings?IP: Logged |

nuum, yes I do but this is a very small part of the changes.. mainly to un-do whatever was done to keep the planes from stalling in the first place (the wings get a sudden artificial gust of lift after stall to keep the wing from stalling). Colome, I have a little trouble following your english but yes both of these types of drag are modelled. However drag for other parts of the aircraft that don't have airfoils like the windshield or nose have to be accounted for in other ways. Check out this plot.. the blue areas are high drag. http://firelight.dynip.com/planestats/ECAaddon-BEWARENotRealStats/190andspitanalysis_files/fw190a.jpg ------------------

Tail i like the fms i think they ready for 5.3 except!!! 1 lil prob with the 51.The 51 has a real bad pull to left on take off i cant correct it with rudder,other then that its nice,just a bitch to take off again  .IP: Logged |

Zurawski mentioned that too.. I'll have a look at it see what I can do. TS

Hi Tailslide,I'm having a problem with the BF109G 5.3 Final--it keeps punting me back to my desktop. I downloaded the .zip from the Open Plane Projects web site and installed the files. When I tried to enter a mission (one of Jeeves' Dover campaign missions), it would go through the checklist and then kick me back to the desktop. So I tried going into training missions for the various A/C I downloaded new FM's for. SpitV worked fine. But BF109 training mission did the same thing as Jeeves' mission: it kicked me back to the desktop once the checklist was complete. I re-downloaded the BF109 file in case it had been corrupted during download, but the same thing still happened. Any ideas? Any help would be greatly appreciated! Thanks!

Ooops! Ignore my previous post--I found the problem. I hadn't copied the Startup.ppf file for the BF109. Once I did that, everything worked fine. I put it in the FighterSquadron\Media folder, and that did the trick. Just out of curiosity, what does this file do? Does it have to be in the Media folder, or can it go in the Media\Aircraft\Bf109g folder? Thanks in advance, and thanks (to everyone) for doing so much work on the FM's! IP: Logged |

The startupp.ppf file references a bunch of .SMs. It basiaclly says, heay, these are installed and load them up when the game starts. If you have the plane pack, you should modify the startup.ppf file in there rather than using a different one. If you don't then the stuff in the planepack won't work.------------------
Cheers!

Ok I posted another p51. I can take off ok with it and so can the AI send me the mission if you still have trouble. I ran the harbour strike mission, all ai took off ok including spit 190 and p51. I notice the p51 pitches down really sharply like the p38 used to with full flaps so the spit landed ok but the ai p51 took a header into the ground on landing when dropping flaps. I'm not sure what got changed on the p51 to add this effect so I don't know if I can take it out. TS

RE: Starup.ppf & the 109gAronsky, The .ppf that is included with the 109g has an additional airfoil for the 109 added. Other than that it's the same as the PP5.2's startup.ppf (So .. no need to edit or change) Razer ... come on ... I'm better than that! (to not edit the PP .ppf)  IP: Logged |

Ran into a problem with the Spit MkIX, The gear isn't visible when extended from an out side view. It looked like it was always retracted, but i slammed the plane hard on the ground to see what would happen and one of the wheels suddenly appeared bouncing across the ground. I guess it was extended even though I couldn't see it.How do I get on the list for testing FM's and sending in bug reports? Thanks,
