Re: Chinese ht motors kits for $21
Watch out for Alibaba, lots of crooks (ask me how I know). No reliable feedback like Ebay.
However that dealer is probably legit as that was going rate last time I was in ShenZhen. What they don't tell you up front is it costs about 3x more to ship than cost of engine. I found it better to just wheel and deal with middlemen like BGF, Zoom, etc.
