Here we go... Lego is going down

Armed with a gps speedometer, 3s lipo and dreams- this K'nex rc car I built will hopefully hold the record for the fastest RC car made from a kid's construction toy. Lego builders have done speedruns and personally- I think the fastest ones were cheating quite a bit by using 3d printed gear boxes, steering etc. So, here's my much more authentic attempt. Tires, springs and electronics are the only non knex parts. As these Speedrun attempts should be. Wish me luck! Aiming for 65mph!
