Arduino+IMU over Xbee to another Arduino+IMU - Feasibility

Projects General Guidance
1

Hello Good Arduino Folks! This question encompasses many aspects of a prototype design, but we have hammered out many details and I would like peoples opinion on the overall feasibility of this project. I would also like anyone to address their own personal concerns and also make suggestions! Here it is in a nutshell

This project is essentially a helmet which guides a pair of headlights on a motorcycle. You look left, they look left. (helmet controls Yaw axis) Also, you turn left (creating a bank angle), they redirect their aim up from the ground (by adjusting on the Roll axis), so that the Yaw can be adjusted correctly via the helmet movement. Here are some specs

  1. Helmet has MPU6050 IMU + Arduino Fio (3.3v, 8Mhz) + Xbee TX (series 1) + 3.7V li-po battery.
  2. Bike has Arduino Uno + xbee shield + xbee RX (series 1) + MPU6050 IMU (level converted) + 4 servos (2 sets of 2) + 12V
  3. The 12V source from the bike battery itself is regulated to 6V for the 4 servos, regulated to 9V for the Arduino Uno.
  4. The helmet IMU is for adjusting Yaw axis (aim left, aimright) while the Bike IMU is for Roll axis (rotate clockwise etc)

Concerns:

  1. Would there be issues in Xbee communication considering the different operating speeds of the Arduinos? (Fio TX = 8Mhz, Uno RX = 16Mhz)

  2. Very general - what are concerns / feasibility of the bike's electrical system? We are not as electrically savvy as we should be. (I'm a programmer, my partners doing the mechanical design)

  3. Maintaining accuracy in read (IMUs) and write (servo movement) and ensuring they are in correct position.

  4. Any other concerns you experts might see I would like to know more about!!!

Thanks for looking
