Fun to watch the bikes screaming down the straightaway. I can't figure out how they get them to lean on the curves. The only model racer I had as a kid was hooked to a straight wire that ran through a couple small eye screws under it. In the back was a small CO2 capsule and you used a special spring loaded doodad to puncture it. Sucker would pass anything on the road for about half the length of a football field.
Hit the neighbors dog once when he started chasing it, he had to take him to the vet for some repairs and wanted me to pay for it. Good luck on that one, told him his dog wasn't supposed to be running loose like his wife was while he was on the road(truck driver). That ended the conversation....and apparently the marriage judging by the moving van that showed up a week later.....but I digress.
