ArduCopter

The quadcopter built by the team, when flown over a distance gives an altitude drop of around 3-4 feet.

The specs for the the quadcopter are as follows:

Propeller size: 30*10.5

Esc: Flame 80A

Motor: Antigravity MN 8014 kv100

The logs and parameter file is attached below:

Please help me in figuring the possible reasons for the altitude drop, and hence the solution for the same.
