Hi Max,
Yes you got a Chinese copy of the RCGF engine. I do remember sending some 30T parts up to you. I know that the jugs say RCGF on them but it is still a copy and not the real deal. If you need any more help with it let me know.. I run the warehouse and service center here in the USA. We will be in Toledo this coming week end 4-1 to 4-3 for the Weak Signals hobby show. The sad thing is we sell the real 30T for $369.99 and it has a 2 year warrantee return to me for repair. We also ship for free. Sorry for your bad deal...
