This little crawler did an excellent job. I thought I was unlikely to find a smooth enough line for it, but it did very well. Tyres are a little low on profile. Which affects grip a bit. But they are soft enough. Purchased from Bangood.
It was a glorious day. I recorded this a while ago. Sadly the weather isn't quite so pleasant now. I think I need to but more boats or amphibious vehicles! 😁
