RC48. My Memory Having RC Car. My No 24 RC. Yonezawa Hi Power Off Roader Buggy The Missiler 1/10 1984.

On 14/10/2018 morning another sunday, go for treasure hunting in flea market Seremban. Stall after stall go threw nothing intrest me. Last is a second hand shop. Just went inside at rhs my eye cought attention on a box that a buggy rc picture on it. Closer look woooooo is a 1/10 buggy, look at the box all badly damage torn. Take it to a side and open it, wala a red buggy inside, a remote, Folded instruction manual, the battery charger. Take out the buggy and check the rear tyre already damage and motor can't turn. Looking for the brand Yonezawa, i have no idea. But made in japan. Ok i want it, the prices on tag Rm80, ask for best prices Rm50 but ask to reduce to Rm40. Deal sold yahoooooo. I buy another vintage RC 1/10 Buggy. This my 24 collection.
After paying go to a shop taking my breakfast and slowly look into the net and found out it around 1980 Under YONEZAWA CORPORATION JAPAN. This the second model 1/10 buggy from Yonezawa Corporation My is from 1984 according to the instruction manual printed, but in the box is 1985. The box buggy is yellow but my is red.
