Yeah, the buggy hits top speed about 75-100ft past me in the vid, but I was in the way of the cam. I think it's actually too fast for the track I plan to use it at, but oh well.
I took a video of the slow speed performance. It's a little better since I was able to prop the camera somewhere stable. Don't mind the hanging sheets in the background - It's a ball net so my son can practice hitting tee-ball in the house without breaking anything. :)

That's as slow as I can go without it stopping. Notice no cogging? :)
