Hi Trevor

Thank you for the reply, I'll go with the tank style steering. As I'm getting through the build diaries in my spare time I'm catching on to why a lot of the robots are build like they are. Why make all the mistakes when most of them have already been made I suppose. I've looked into it properly since I posted and I've realised it's going to take a big servo and a lot of trial and error to get right. I'm computer/electronics based so will play to my strengths with the ESC and tank style steering and leave the complicated fabrication for now

Thanks again

Dave
