Impressive. We used to go and watch an R/C airplane speed competition at the Whidbey Island Naval Air Station every year. The Navy actually sponsored the event, and provided RADAR to verify speed. This was long before today's miniature jet engines, so all of the "jets" were powered by two cycle reciprocating engines driving ducted fans. The best we ever saw was in this range, 230-240 mph, and they were in the air, not on the ground. Just maintaining visual on one of them, even not being the guy trying to fly it, was difficult. Driving this car must be very difficult.
My younger son and I raced R/C cars when he was about ten until he turned about 15. "Gas" (glow fuel) power outdoors in the summer, electric in the winter indoors. Here are our two gas cars, 1/10 scale "touring cars". Class rules allowed .12 ci two strokes with some internal limitations. I converted a .26 ci four cycle for my car, which everyone was fine with, although not technically "legal". We had a ball. I really miss doing that with him. Gas cars are, unfortunately, dead. Modern lipo batteries and brushless motors killed them. Really too bad, something about the noise, smoke, smell, goo, and all of that really made the gas cars fun.
These things might have hit 40 mph on a good day. That was plenty fast, believe me, with a dozen or more racing in a pack.
