Hi everyone!

Bought the CS777 a while ago. So far I'm not to satisfied.
I found a few problems, but Google isn't much of a help finding answers.
First, taxi speed. Even if I load up that bird to 100% and start taxiing... It keeps accelerating and if I wouldn't use continuously the brakes, I'd go way above 30knots. I'm unable to adjust the throttles. They're stuck at 21.5% until I'm ready for T/O. How am I adjusting the throttle settings, beside in the fsx menu?

Second, strobe lights. The strobe lights look more like on an Airbus. Tried to adjust the strobe lights in the CFG file but that didn't help. Any help pls?

Third, horizontal flying. At Mach .81 and fully loaded, my airplane is laying like a flat board in the air. Completely horizontal. Tried to play with the trim, but I'm aware that this is more for T/O.
I'm a flight attendant and quite often on the flight deck inflight ... So I know that the 777 is definitely NOT 100% horizontal. It's about 5% over the horizon. So... How am I able to adjust that?

I know, it's a lot of questions... Any help is appreciated!
