I'm led to believe that V3.01 on an APM2.5 cannot fly octocopters in anything other than Stabalise/Alt Hold modes due to overload on the processor bringing the 50Hz loop down to around 5Hz.
1. Is this true ?
2. If so why is the firmware code still avai

Implementing PID controller requires calculation of error, integral of the error, and time derivative of the error. Good attitude system (like the DCM that I am using for my quad) usually provides quite smooth estimate of error; integral error eve

I just wanted to ask where in Mission planner code loiter radius is limited? I couldn't find it. We have quite big project using APM and loiter limit is to low for us. When re-uploading WP's, radius jumps down to 244 (I think)
Thank you for answers

I've been flying a lot of AUTO mission lately and I have noticed a persisting problem. My quad with ArduCopter 3.0.1 never wants to face the direction it is going, nor does it turn towards the next waypoit, it just 'strafes'. In other words the

Can the current offering of the APM: Plane accommodate a modification to use a camera (such as a Canon PowerShot) as a payload shooting straight down?
The pictures for this product appear to only show a forward looking camera, more suitable to FPV.

We've taken a 3DR Quad and changed it a bit to try and get more payload and more flight time. Here are the current specs:
Motors: T-Motor MT3520-11 400KV

Props: APC 13 x 4.7
Battery: Zippy 5S 5000mAH
