Arduino vs raspberry pi

Hello people of tek syndicate.

Me and a group of friends are getting together to build an RC plane with driver assists such as GPS and autopilot, the plane will have a 2 metre wingspan, the recommendation is for processing all of the thing that the plane would need to do. would you recommend using a raspberry pi or an arduino and why. if there is something else that you would consider to be better please tell me about it and I will take it into consideration. please don't recommend anything ridiculously expensive as we are only 14 and as a result do not have much money to throw at it. also bear in mind that some things may not be available here as we are from the UK.

yours faithfully Neil

I would say arduino because there are a lot of TUT out there. And I would say it's easy to use because the arduino platform is directed at schools and learning.

Why not both?

Seriously, though. Use a microcontroller for real-time applications like running the motors, reading sensors and stuff like that (arduino is good for prototyping stuff). Use a bus system like I2C to communicate with the raspi and do all the logic and other heavy tasks there.
