corse.....
I respect your opinion......and I'd like to say that i agree with you in many techinal points you comment around this forum......

when I refered to crankshaft breakage you may know very well waht engine i refered to.........you seem to be a fan of sirio engines as I can read on sirio engines topic, and YES, if you got an evo3 and haven't had any problem with its conrod or crankshaft you're a VERY LUCKY guy....not to mention the previous versions which seemed to work only for official drivers at WC events.......

regarding quality control, recalling an engine is definitely not a thing we can say "WOW, what a good quality control", it's in fact a good posture of a manufacturer....

I know at least the basic of how a product is manufactured since I study mechanical engineering.....and I also know how much money you can save to put any product in the market by eliminating some secondary steps of its production.... I'm not saying that any r/c model engine manufacturer does it, just saying that R&D and full QC make every product expensive.......
marketing is extremely important as well, and I have to agree that during the last years other brands had better teams than Novarossi, and in r/c racing the 1st place is what really matters......if a Nova engine was the currently world champion it could cost US$1000.00 and everybody would want one.....hopefully collari, salemi, tanaka, balestri or other top driver can change that....

well, everyone will defend their favorite brand......we can discuss about this subject till the end of our lifes, it's like soccer
