An update on the RC8.2, just found the fuel line provide from the kit is so easy to break. I found some small holes on the fuel line last Saturday that make the engine tune not stable. I think it is due to when I remove the engine for regular maintenance. Finally I bought some Japanese made fuel hose (also found they are smaller in outer diameter, harder material), will see if it is reliable than the original.
>>andrewlau haha, ching, take your time, KRC is quite technical track and need to tune the engine good, a lot of jumps rught after sharp turn. Try to use harder clutch spring may help. have fun!<<
