Well I wasn't personally attacking your motors but since you felt the need to correct me let me clarify, I was saying why buy a cheap mill such as these, gotech's, alphas for $200 and then have to put a quality carb on them http://www.amainhobbies.com/product_...lus-21-5-T21BF to make them run right, why in the world would you ever buy a replacement carb from the same manufacturer if the original didn't last but a couple gallons? I've seen this game before, the money is always saved by using cheaper materials, if the materials were on par of the other major manufacturers for less money there would be no rb, novarossi or o.s. Every few months or so some new motor from the same taiwan factory comes out with a different cooling head that everyone deems the latest and greatest budget racing mill. And it is always the same story, you have to tune this different then other mills, theres a different break in process, you have to rerod it at a gallon. I really don't care what people run or spend there money on but don't tell me I should read or know more before I comment, this is just another rebadged tawain motor and there's nothing more to know as they've been out for a while.
