Thank you for the links and info on ReadSpeed. I spoke to them today and Matt is away but hopefully back end of the week, and can then go through the finer details. Guy I spoke to though was very helpful, and they sound like the people to deal with.
I've just been watching a whole lot of youtube videos on hot minis! I have to be strong though, I didn't buy it for that, but I'm so impressed on what they can achieve even with the A series engines. There was moke up here that was advertised a few months ago that had the R1 conversion done. I was tempted, and I thought it was cheap (high $20ks from memory), but I wanted a mini. And I really don't want anything else that will risk my license that easily
