I JUST got my quad working fully (Quanum Pico + Turnigy 9xr with OrangeRx module) thanks to sloscotty.

When I take off, the quad just goes into a crazy yaw spin.  I've tried trimming via the TX but that doesn't help.  I've tried manually applying opposite yaw, but that just makes it spin the other direction.

I THINK the problem might be that I have the motors on backwards.  Normally motors spin inward toward the body of the quad, but mine are all swapped so that they spin outwards away from the body.  Would this be the cause of my yaw problem?  I'm double checking before I try to go soldering the tiny wires again because I think it was a miracle I got them connected last time without any screwups.

If your motors aren't turning the correct direction, you'll want to fix that first (and make sure propellers are correct as well):
(from above)
CW-----CCW
------^-------
CCW-----CW

If those are correct, try reversing channel 4 on your transmitter.

It was the motor directions. They were all spinning exactly opposite from what they should. Flipped them around and it flies like a dream!

Aha that's good to know! how did you change spin direction, swap the motor wires?

Great jamesw!  Good that it is finally flying!!

Just swapped the motors!  
Moved back ones to front and front ones to back.
