450 clone noob question

Ok guys let me say I am a noob and only been flying since July but catching on. A month ago I thought I would build my first 450 clone. I bought a copterx450se because i did not want to spend a lot because I knew I would crash. anyway long story short I just completed it and I have to say I am glad I built because I learned a lot.

Anyway trying to tweak it in when I hover - when I move the sticks man this thing moves fast is there anyway to slow it down a bit. When I move forward or back and side to side this thing moves fast and I have to over correct fast. Is there a setting that I need to tweak down? Or is this normal and its just me used to a smaller helicopter. My other helicopter is a walkera 200 and it seems to move alot slower. Maybe its me and I am not use to the bigger 450 but this thing turns and moves on a dime.

Also I have pitch curve and throttle curver set normal on it but when I increase the throttle it does not come off the ground until I am at 70% to 80% throttle. Maybe that is right and I am just use to my smaller helicopters where about half throttle they come up off the ground.

Anyway maybe it is just me because this is my first time to fly a 450 helicopter but man this things seems to move fast when I move the stick.
