Well , I`ve always had great succes with Rc Mart[Dinball] . Not only the engines, but parts , glow plugs and many transactions with them . Too bad you guys had a bad experiance . I normally get things with in 7 days and at least for my orders , shipping was fair . They even overnighted an engine for my 8ight so I could race it the following weekend and it was only $20 for overnight from H.K. to IL. But everyone has their onw experiances , there is support for the engines through Global Hobby [a known distributor] .
