Just want to share it with all of you..

BTW: i did it with round tube first.. then ported the idea to square

Carrier Plate / Carrier Board / Accessory Mount

Everyone seems to have standardized on 45mm screw spacing for their flight control boards (paris/fly/divide). Does anyone have a source for cheap / light / plastic carrier boards for mounting accessories pre-cut at 50mm with 45mm hole spacing? Seems like this should be everywhere, but HK and the other usual suspects don't seem to have.

I suppose ponoko might be an option if no one has done this yet. The arducopter guys have something simple like this:Arducopter carrier plate v1 but they built to 80mm.

Even if you bring the stick back to zero, it is still trying to get to the older position.
Why would it try to get to an "older position" if that older position is no longer where we are commanding the quad to?

If the quad is level and the TX stick is at neutral then isn't the quad at the commanded position, regardless of if it is in the air or on the ground, for which there should be no accumulated error?

If the quad is on the ground and we give a right roll command of 10 degrees, I can see why the error would build up past 10 degrees if the quad is not allowed to rotate to 10 degrees. But if you hold the quad in your hands and roll it to 10 degrees, the accumulated error should go back to zero since the quad is now at the commanded 10 degrees of roll. In the air or in your hands, 10 degrees of roll is 10 degrees of roll.

If the sticks are at neutral then the desired roll angle is zero. If the quad is level in the air or on the ground then it is at the desired roll angle of zero for which the error should be zero and the motor commands should be equal. Zero degrees of roll on the ground or zero degrees of roll in the air is still zero degrees of roll. If not then I'm missing something here

Yes, but I don't think the system is that perfect. I have always found that if the quad is not allowed to move when the stick is moved, then the outputs never fully equalize out. I have never had a problem in the air however. I am not sure if the I term is ever set to zero in the MW code.

New Board and shield

Details
1) 8 PWM channels for 8 motors.
2) 3 Dedicated Analog channels for camera stabilization and trigger.
3) 4 Extra Analog channels for whatever.
4) 2 UARTS: RX0, RX1 and TX0, TX1 for GPS, LCD or wireless, etc.
5) Direct drop in of BMA020, Sirius, Atmel, Pololu MinIMU-9 sensor BOBs.
6) Sketches up to 130048 bytes.
7) Standard 45mm mounting on the shield.
8) Direct plug in of Receiver.
9) Motor connections where needed so no birds nest on top.
8) Built in LLC if running the board at 5v but all test indicates that the board works fine at 3.3v so no LLC needed for 3.3v sensors!

Memory comparison:

Feature 328P 1284P 2560P
---------------------------------------------------------
RAM 2k 16k 8k
Flash 32k 128k 256k
EEPROM 1k 4k 4k
UART 1 2 4
IO Pins 23 32 86
Interrupts 2 3 8
Analog Inputs 6 8 16
PWM 6 8 14

Cool.
How about some innovation?

Feature STM32F103C8T6
RAM 20K
Flash 64K/128K
EEPROM Use flash as eeprom
UART 2
IO Pins 37
PWM 4 16-bit timers with 4 channels each
Features DMA, USB
Timers 4 16bit timers, 32bit systick, 32bit cycle counter
Analog 2 12bit ADCs, up to 7.2msps sampling rate x 10 channels

The board: 36x36mm [the new standard]
6x motor outputs
8x pwm inputs reassignable to motor outputs when using PPM
