Deltasim PTBoat flight model update 1.

This updates and supersedes the previous mod. this update corrects the heavy nose down pitching effects seen at 35 knots, and corrects handling throughout the full speed range..
Unfortunately it mostly breaks prop reversal. The props are their normal 2.35 foot diameter so they arent producing quite the same amount of power per revolution as they did when they were 8 feet in diameter. They will slow and stop the boat fairly nicely, but i'm still working on reverse.
Be gentle with the rudder as you can now swamp the boat at any speed..
The update can be found on the bottom of the page located at http://www.sim-outhouse.com/sohforums/local_links.php?catid=4&sort=h&page=5&pp=20, or you can search on PTBOAT, PT or my name..
I hope you enjoy this one.. its a bit different, a bit more realistic.. A little less cowboy and a little more machine..

Thanks Pam, just downloaded and will give her a try. Thanks for the work on this beauty.
 
Thanks Tom.. Please do make sure to point out anything you see amiss.. Since Paul doesnt have this model, it was just me working on it. Now, when he and i work together we can do some mighty nice things, but, i dont hold such confidence in just my work alone. I dont know how it will run on someone elses machine, and i greatly appreciate the feedback..

Thanks Pam,

In general I think the speed is much better. Stabilty is improved, but I have the feeling this makes turning at medium and high even more difficult.

you should just be able to be a little more gentle on the rudder.. its quite responsive now.. if your using the flaps make sure to raise them before turning as they not only increase the lift but add stability as well making turning at high speed a bit more difficult..
 
Pam, I agree with Huub, the turning ability as decreased. I will do some more testing. My current project is trying to create some MESH for Anatahan Island and Sarigan Island both north of Saipan. Back to the PT Boat.
 
ok..
i'll make an adjustment which should help a lot.. I think i already know what it is.. gotta run to a board meeting but i'll be back in a couple hours and will get that too you.. :)

Pam, after retesting, just a slight adjustment on the turning would be necessary from my side. The other performance characteristics are fine. Thanks
 
The latest update is fine apart from the turning as stated by hub vink and Stovall.
Speed is very good compared to the standard and the ride height is spot on now.
Thanks for doing all this Pam, I love this boat and never thought we would ever see one in FSX,
with all this new WW2 scenery it has been a hell of a start to 2013.

i'd certinly hate to clog up the server.. and ive got no means to delete the old files off the soh s3erver.. Could you PM me your email and i'll send it right out too you???
 
Pam, I must be doing something wrong but I can't get the boat to move forward even at full throttle. Ideas?
 
wellll, i dont think your doing anything wrong.. i think its that each propeller os only 2.35 feet in diameter and in fsx water isnt any different than air unless you hit it, so it takes a lot of power to get 70000 pounds moving with those tiny lil props.. I dont know what the specific density is for water, so it would be hard for me to make an exact scale up for the props.. but i'll do my best real quick.. You see, i think what the problem was earlier with the turn ratio was the altitude of the cg. I had placed it at deck level to account for all the steel on the deck. But to fix the turn radius, i dropped it.. With a high cg, the boat comes out of the water sooner and reduces the drag on the hull, but it also makes it unstable. With it lower, it rides flatter ( numerically ) but is more stable..
I'll have to experiment a little to see what i can do..
