OK, so it's easily done to tip these small guys over on ice and snow... here's a solution that works great for me! Tarot 450 training gear:
They have a wider stance and makes it much more stable!
You need to drill 4 new holes in the plastic in order to make them fit. Tarot has stopped making them, so hurry up if you wanna secure some...
The canopy is some el cheapo I bought on FleaBay and painted myself. With "starboard" etc colors... It's made for T-Rex, so you need to trim a little and make 2 new holes.
