Thanks, I'll be sure to let my brother know you liked the music!
Originally the bird did tilt up and down but there was a problem with it vibrating when it came to land so I had to take it out. I didn't have enough time to fix it before but I'll give it another go some time this week. Also the navigation system for landing is really janky for many reasons. I'm going to continue working on that though, probably cutting momentum when the bird lands would go a long way towards helping with landing... hmm.
