I can echo what Anthony is saying. I have two copters (UAP2 Y6 and quad, both around 4kg) and both have the tendency to tip when applying throttle to slowing during takeoff. So I just apply something like 20-30% throttle in the beginning, which isn't enough to make it tip and then quickly, but still smoothly, advance the throttle to 50-60%. I know with a new setup this is a little nerve wracking, but if you made sure all the motors turns the right direction, have the correct number and props are installed correctly, it will work.
