got a new WM+, hoping I killed the other one, and thats why I can't get it working. I'll try to get things hooked up tomorrow. I'll let you guys know if it works.

Okay here is a total noob question how do I connect my Esc, servo and rx channel to the Arduino? Hardwire or do I need a certain connector?
Thanks

I'm almost finished with my build.
Can I get more detailed info on when the full throttle thing can happen. Full throttle is kind of scarry.

Solder on male breakout header pins and use female to female jumper wires to connect your receiver and female to male jumper wires to connect your ESC's. Sparkfun has what you need.

When you go full throttle, there is nothing for the moment to prevent all motors to spin at their max, and indeed to use a good gyro correction.
I have to code something to limit motor values so that gyro corrections can still be effective.

You can also buy some servo wires. Female plugs are compatible with breakout header pins.

Yes because the Arduino needs 5V to run as well as your RX does too.

one more dumb question - So if I power my bec from balance plug of my battery - should I connect my servo, esc's, arduino and rx all from the bec? I am assuming this is okay or will it mess up my power up sequence in anyway? This is how I do it on my tricopter - main battery power to ESC's then plug in charge plug -

Since I've never used an Arduino I can't comment on how and when it needs to be powered. I don't see any issues in using the balance plug to power all of that stuff as long as you don't have a BEC that is a POS.

I will soon see as my parts from Sparkfun should be here in a couple of days as well as my motors and ESCs Just need to figure out the frame.

The BEC is needed, but it is already included in each ESC.
An external UBEC is not needed.

I just finished loading my first sketch onto the arduino - took me little bit to get the pins to line up correctly and stay that way since I dont have any header pins yet - now waiting for Wii motion plus -

Hi,
I tried to integrate a nunchuk, but apparently I got a very bad copy of it, single side pcb.
It works, but its step resolution is about 5 degrees. I can do nothing precise with this.
I just ordered another one, with the hope it will be good this time.

Hi Alex, will the ADXL322 dual-axis accelerometer work with your design ?
