I've had a crawler course in my garden for years. I had quite a few wall building projects with big piles of stone lying around so I've made the most of it for my crawlers.
It went most of the way round the garden. I've made a few bits permanent with cement and stone. But most of it originally was stone and rock piled up.
Like my stupid user name suggests I live on a steep hill. It's probably nearly 30ft from lowest to the highest point in the garden, so there's plenty of steep climbs and descents.
Here's a picture from the cctv which shows most of the recent work I've done.
It's good for 1/10 crawlers and good for mini crawlers. Trx4m is a great size for it.
The terrain is very unforgiving (when the truck tumbles down it) , mainly sandstone and a strong mix of grit or sharp sand, so very grippy.
I've done this so hopefully I can use it all year round. The other stone found in the local area gets slimey in the winter or very wet weather.
The Trx4m tarantula is very good on the course.
And here's the Bronco coming down a section..
And here's another little line in the Bronco...
Thanks for looking and if anyone else wants to show your crawler course, please do.
