Hello
Can you send us the eagle files or upload them to the paparazzi hardware git repo ?
Maybe some people could check them, or search for improvement opportunities before they are oderes.
(servo pinout with 3 pins and seperate (screw) terminal for power supply, tactile smd push button instead of jumper for BOOT, smd crystal, no screw terminal under the dicovery pcb, right of the pcb could end flush with discovery board, mounting holes, BEC input caps, possibility of mounting a chinese mpu6050 breakout
ebay link direct - on the pcb (no 10dof since the mag will not work well in this position), looks like max7450 is getting discontinued by the manufacturer, i2c pullups)
