thanks I'm glad you like the kit.
I studded my track with finishing nails with the large head on them.
I put one every other lug and only one for each side just make sure they are out of the line of the wheels.
Mine has no problems doing wheelies on ice
I am slowly getting back to having everything running I use to get only 2300 rpm from my mill now I get 6793 rpm should
help with cutting parts faster.
I am still tweaking the wheels for the ski's so it can be run in the summer just like in my vids on youtube.
