My 4yo boy had a gptoys s911 car for a year, its a cheep rc car 50 bucks from china. Its fun little car but it required lots of maintanence.... you get for what you pay for.
so i have decided to get some better truck that would not break as much.
i found Losi xxx sct, used, in craig lists and i bought it... what a mistake!
5 time driving it 3 times replacing parts, a arms, 2 times bulkhead. It is too fast for him.
cant tell would it be fine for 6yo, but as already mentioned speed is not for them.
I can only tell he needs 4wd so it ca go over high grass, buggy or MT with moderate speed, max 30kmh.
