Apm 1.2.99 problem

I installed mission planner 1.2.99 on a new windows 8.1 computer and it seems to work ok, but on the Config/tuning screen I no longer have the "Advanced Parameter" list or the Full Parameter list. I haven't completely checked out the .99 version, but

apm2.5 magnetometer

Is the onboard magnetometer on the apm2.5 of any use? It seems to drift as much a 30 degrees. I think I read somewhere on the forums that an optional magnetometer is required for position hold etc. Can the onboard magnetometer be initialized/zeroed?

Short Flight times

I have constructed a 450 bumblebee quad and am now flying it with the APM2.5. It flies great, but I am only getting about 3 min flight times. The motors are 2832 1200kv with 10 x 4.5 props and 20A esc's. I am using a 3s 2200mah 25c battery. The quad
