#1 I have a G920 wheel and I've played around with a few different rotation rates and it doesn't seem to make any difference with HydroSim. My suggestion is just keep playing with it the way it is and you'll get used to how much to turn the wheel. Hopefully down the road we'll be able to actually adjust that but for now I don't think it works.
#2 @CanYouFoush is right about this. The game's physics aren't completely accurate so doing what they do in real life isn't the fastest in the game. You want to get as much air under the boat as you can without blowing over and it's easier to turn when the canard is down.
#3 The only time I lift is in the roostertail turn or if I fly the boat too high and I need to lift to get the boat to come back down. Other than that it's foot to the floor all the time.
Weekdays are better for me, I wouldn't start any earlier thsn 8:30 eastern (5:30 pacific) or it'd be tough for the west coasters to make it. Another option (if enough people are interested) would be to do a separate west coast and east coast series with the top season points drivers having a championship race at the end. Obviously you wouldn't have to live in the region, just go with the start time that's best for you.
Thanks @Ryan-Yates that is helpful. Unfortunately I'm not entirely sure how I'd use that in the physics calculations. What I envision for figuring out the lift generated by the hydroplane tunnel/air trap would be to setup a grid of points at an angle. I can then sample the water at the center of each square to find the height above the water. From there I'm not sure what the equation is to figure out the lift force exerted by the air pressure. I'm thinking it may be similar to ground effects.
Thanks for registering! Unfortunately, the U-9 Delta/RealTrac has already been registered by another user. You may use the U-9 Jones Racing boat if you wish, or any other boat that isn't already registered.
