First of all,it s not your fault about anything.You kindly shared the information you had and i m thankful for that. Second,dont confuse experience with "database knowledge". I have 22 years of rc experience.Does that automatically grant me the ability to know every single clutch carrier size or know every single car clearances? Most definately not! Experience has nothing to do with this,if it did,i would have already broken in the engine by now.
MCD SHOULD list compatibles engines period!MCD should provide all the information a customer needs since he is PAYING to buy their product. Unless losi,hpi,arrma and all the other major manufacturers are stupid.
Last but not least,i didnt put any oversized engine anywhere. It s a stock zenoah. It s an off the shelf basic motor that i bought AS A BUNDLE WITH THE CAR. I didnt try to put a malossi or a polini engine in there,nor i tried to put a pocket bike engine. There is absolutely no excuse for all this.Anyway,i ve said enough,i ll hack it up and make it run
