I had some problems and burned out an omo servo a while back. It was locked up so that meant I had to take the whole chest apart. Major hassel so I was unmotivated and didn't work on it.
I mentioned it in the shoutboox and Mats gave me a suggestion. Don't just replace it but do an upgrade. Make something better in the process so it is moving ahead in stead of just reachieving what I already had.
