Hi guys, below is a video of our quadcopter. We built it using aluminium square tubes.
Here are some of the electronic parts,

with APC 8x3.8 slow fly props.

APM 2560 with "ArduCopter V2.0.49 Beta" loaded
and set to X-frame and simple mode selected.
Below is a video of us flying it.
We realised the quadcopter is always 'running' (or you call it drift?) around too much in the alt hold mode. Even when i tried to bring it back using the transmitter, it 'ran' (drift) off again.
Any advice for you guys?
Thank you!!

Hi, thanks for the help! :)
From Arducopter wiki:
Make sure the CG (center of gravity) of the copter is dead center. Then run the level command on a flat surface. (hold disarm for ~15 seconds to invoke.) You can also fly in auto-trim mode in a windless (important!) environment--any wind will cause the changes you make to work against you when the quad rotates 180°. Hold arm for ~ 20 seconds to fly in auto-trim mode for about 45 seconds. It will exit auto-trim automatically and fly normally. (Don't worry about counting out the time, just wait for the flashing lights to enter either mode.
You are refering to this troubleshooting section right?
I am going to try this auto leveling.
Just to check with you whether my steps are correct if i try this auto leveling.
1. First i take off in stabilize mode.
2. Upon reaching knee level, i switch to Alt hold mode.
3. Then i arm for about 15-20s to enter auto leveling mode.
4. Let it fly for 45 seconds and then switch back to stabilize mode to land.
Are my steps correct?
Thanks in advance! :)
You can run auto leveling in the air to tune it. Check the wiki. You hold arming for about 15 seconds to enter that mode.
You could use some tuning too. Check out the CH6 tuning options in the CLI.
