Have the above setup, all very stock. I have just received my APM 2.5 to replace the stock gyro that came with this quad.
I am stuck on connecting the ESC's to the APM. After reading this: http://diydrones.com/forum/topics/powering-esc-s-with-out-the-distrabution-board
It looks like the jury is still out on whether or not I can just connect all the 4 3-pin ESC leads to the outputs on the APM. I've seen a few other threads on people using this quad and it doesn't seem like they've even considered it.
I'm thinking with 2.5 that I'll be able to just connect them all without issue. I'm also using the uBlox GPM and MaxSonar EZ sonar but have not connected them yet.
Can someone please help me and let me know whether or not I can just connect the leads?
