Thanks for the info. I've been contemplating which paddle steamer kit to get (OcCre, MS, Dumas,...) but I think I will go with the Graupner. I've built a Graupner RC helicopter before and the quality was fairly good. And it's the only kit, besides the Dumas, which is designed for R/C. I also don't love the Dumas, it looks somewhat "cheap" and the reviews aren't great about the quality of the wood.
So, my plan for the Graupner is to mount 2 separate single cylinder engines and drive each wheel separately, allowing for better turning. If it will fit, I also plan to add a 3rd engine to power a generator for lights and the whistle!
Now just need to find the Glasgow in stock for a good price...
