Ran into my self with the buggy. That hurt. Straight into my ankle. At full speed. At the time I was going to hit the brakes but I forgot that my trigger was broken and yea.
Don't run it into yourselves or others. I ran my 1/10 scale cars into my ankles. That hurt. Wonder what a 1/6 or 1/5 would to. Run the car in a big open space.
Other safety precautions would be like LiPo safety and all.
