Are those 1/10 scale? Almost look like 1/12 scale.
Electric cars today with brushless motors are crazy fast.
Raced RC on road cars from 1973 to 1990.
Started in the mid 70s when I was 15 with the Jerobee 2 ch brick radio with the .049.
Our track was in the Costa Mesa Ca. at the Briggs Cunningham museum parking lot.
It made me a car guy for life.

At one time I was very involved with RC racing.
Racing and also race directing and announcing our Friday night races with near 100 entries.
That was before computers and transponders and you had to manually count the laps.
Had some luck racing in the late 80s.
With help from Ron Paris in the 1/8 scale gas cars with .21 engine.
They were 5lbs and went over 50mph.
Like this but a little slower.
