Same goes for left.

APM2 & Optical Flow Sensor

Does any1 know if the APM2 supports the Optical Flow Sensor?

If it does, where does one connect it and in what flight modes does the APM use the OFS to stabilise flight? Or how exactly does it work?

Running two APMs in tandem

Would it be possible to run an octocopter X4 coaxial with two apms?

I.e. one apm controls top 4 motors, second apm controls bottom four motors.

Obviously 8 ESCs and maybe even dual transmitters.

This would be a truly uncrashable system.

So my alt hold is up to sh*t...

It bobs up and down 3-4meters. Iv tried changing the alt hold P to 0.30, 0.35 and 0.4.

It works the best around 0.32. But it revs the motors too hard and pulses the copter up and down.

What should I change with regards to

Im having trouble with the throttle on my octo.

I battle to hover it. Im only moving the throttle 1mm or less at a time but the thing keeps bobbing.

Is there anything I can do or do I just need more practice?

Drift issue with APM2 & latest APM Planner firmware version

Loiter works great, alt hold works great.

The drift however is a KILLER!

I plug everything in, arm the motors and all is well, but over time (around 20-30s) I slowly have to start giving more and more stick input to keep it in one place. Until eventual

8khz or 16khz ESC setting?

I have Turnigy G10 810kv outrunners. Should I set them to 8khz or 16khz.

16khz apparently generates more RF interference and heat but is more efficient.

and vice versa for the 8khz setting.

Any1 have some advice for me?

Thanks
