Anybody has problem with flying the Posky 737-900?

I downloaded the Posky 737-900 from Project OpenSky to find out what is the difference between that and the 800. The annoying thing about this is that the 900 comes with no panel and they ask you to download the 737NG panel from Posky's site which I cannot find anywhere. So I download some freeware 737NG panel from site like this one and install it in the 900. When I tried to fly it manually, the plane just continues to pitch up like a fighter on a vertical climb even when there is no flaps and throttle N1 is just a mere 45% at 8000 ft. IAS is just 238 kts. I have to push the stick down hard to keep it level and then the plane rolls and banks too. When I tried to land the thing at the nearest airport, the plane crash even when the approach speed is just 145 knts with 30 flaps descend speed is just 800 ft/min. I have not crashed landed a Boeing for a long time. Anybody has any clue what is happening?
Posky said that the plane's flight dynamics is very close to the real thing and have flown by real pilots. If that is how it really handles, I don't want to ever fly in one of these things in the real life.
