fs9 vs fsx flight dynamics?

Ya I've added the realairs c172 flight dynamics to the carenado c172 and they are excellent and I just bought and downloaded the carendo c185 bush version and i've only played around with the tundra tire version I tried both the original and the updated flight dynamics from bushpounders.com for the tundra tire version (could not get the fsx air file to work fs9 crashed) and the only noticeable difference was the fact that the updated cfg entries caused alittle more bounce on rough terriain, i was able to execute perfect 3 point landings with both but with both on rough terrain when bouncing occurs or if I land a little hard the right wheel sinks into the ground, some bush plane lol is there a way to fix the contact point to not do this cuz after a few half foot bounces the landing gear fails.

Hi,

 

may I ask another stupid and slightly off-topic question regarding the C185, particularly the Skiplane. Is there any possibility to pull the fore ends of the skis up to bring them in a parallel position to flight direction (as seen at airliners.net)? Mine hang down as seen when the aircraft is at the ground. This doesn't look nice and increases drag I assume.

 

Thanks,

Harald

Ya it does look kind of odd and I looked at pictures of real ones and they were not like that but the only way to fix that would be to make a new model file I believe, but I could be wrong.

Harald - I can hardly believe that you tested your 185 by flying into Milford Sound! I used to fly 185's and BN2 Islanders into there on an almost daily basis years ago - sometimes as many as five or six times a day in the peak tourist season. When I first flew into there it was just a gravel strip and was sub-standard for commercial air transport operations, so the civil aviation authorities kept a list of pilots who were authorized to use it - and it was a small list... There was a flight service station there and the guy running it would check the list to make sure you were authorized...

 

The truly fun part was on the way into Milford. We would do a low level circle around the volcanic crater-lake that fed into McKinnon Falls at the head of a valley that led down to the airport. There was a vertical drop with water cascading down for nearly 2000 feet. We would pop in through a small gap, circle around the crater with passengers holding onto their seats with white knuckles and then have them look straight down as we would come out and over the falls... It was pretty spectacular. Sadly the authorities found out about it when a major travel movie was released that showed us doing it - and it was immediately banned...

 

Lots of fun and there was never a day when I wasn't filled with awe at the beauty and majesty of that place...

Cheers mate

I never flew the ski version though our company had many of them based at Mount Cook. But as I recall, the skis would tilt when in the up position, as they had to be free to rock up and down around the central axis as well as bounce up and down vertically when landing on rough snow/ice surfaces. I wouldn't swear to that though - it was a very long time ago. But it looked right to me when I first got the Carenado 185... I remember that they were stabilized by bungee cords! :-)


With the tundra version, the contact points do need to be adjusted. I bought it soon after release and wrote to Carenado to tell them about it, but it seems they didn't bother to correct it. I think they used the same air file as the standard version, but the tundra tires are much bigger than the regular tires and so the contact points need to be raised to allow for this... If they are not adjusted, you will get that bouncing and gear collapse... I did adjust it and can sent the info to them - sad they didn't use the info to fix it... Ten seconds of cut and paste....???

Here's what I use...

 

[contact points]

static_pitch = 9.0

static_cg_height = 3.5

gear_system_type=4

max_number_of_points = 9

 

I also adjusted the eyepoint to allow slightly better forward view on the ground]

eyepoint=-5.00,-0.85,2.5

 

Hope this helps

Where are the contact points? because the only difference between those numbers and mine is the cg height and in my cfg its 3.45  not 3.5 but is that all you changed or did you make a mistake copying and pasting?

 

also another note just to praise carenado, when I told them about the issue's with the tundra and float models (the other 2 were ok) and how their fix didn't work and I couldn't fix them they offered a refund or another plane for free, I'm definitely very impressed with their customer service and I would feel kinda bad if I got the c185 working after I got their c337 for free, oh well lol.

Hi Ian,

 

why not? B)

 

Milford Sound is quite well known here from calendars and posters... It's one of the places German tourists dream of and maybe have the strongest imagination of when they hear the name "New Zealand".

 

By the way it was with the C185 wheeled version I tested there, and I only flew a short pattern. Have to explore the places you mentioned!

 

I found no way to lower or raise the skis of the ski version - when taking off and landing, the ski tips scratched over the runway, a disgusting view -  while your description above was indeed my imagination how skis on a skiplane work. There is an entry for a gear lever gauge in the panel.cfg, but I didn't find it at the panel; when inserted into a 2D panel it doesnt't work; neither worked the "G" button or the lever on the bottom which is used to lock the tailwheel in the wheeled version. However, I decided to abandon the ski and the tundra version as I bought the C185 bush package particularly to get the float/amphibian plane.

 

I had no luck with the bushpounders aircraft.cfg as when using it, the planes bounced up and down so strong that it crashed even at the smallest taxiing movement. At the same time I'm quite happy with the aircraft.cfg provided at Carenado's update site as the plane is very stable when cruising and not too tricky when it lands.

 

By the way, I'm currently on my annual Round-the-world trip called "winter journey", at the moment in Argentina/Chile (to freshen memories to real-world holidays...), with my executive 727. After that I will come to Australia and Newzealand, thanks to your tip about the RealNZ sceneries. Nice places for some amphibian operations.

 

Regards,

Harald

Unfortunately my FS9 computer is in storage and has been for some time. I started working on a home cockpit and the project has got bogged down. So it's been ages since I have been actively FSing.... :-(   So the contact points etc. I gave you were from an older backup on the computer I'm currently using and may be different to what I was using previously... Sorry about that... When I get my system up and running I will check the aircraft.cfg and see what the changes were I made in the version I was last using... But do try the 3.5 instead of 3.45 as that should take care of the difference between standard and tundra tires...

Ok thanks, I will try it and see if it works but it seems to be more of a glitch with the plane.

Static cg height/pitch  have nothing to do with the actual contact points. These two just define the height and attitude when you enter slew mode, or when initially loading the plane.

Well Kiwiflyers45's fix actually worked for me and I think it did because the plane may have been loading the contact points incorrectly because the CG position was slightly low previously.
