I’ve had my maxx since they day they landed in uk shops and with the exception of the really **** fans on the motor and esc it’s been bombproof. It’s been used in concrete and wooden skateparks and huncote bmx track where it’s nose dived, flipped, cartwheeled, bounced and crashed as well as landed perfectly and it’s still going strong (apart from the fans. They broke ages ago). I’ve not needed to upgrade it at all. I’ve not replaced anything. Three to four packs twice a week at least, every week since I bought it.
I’m going to fit a wide max kit because it does roll over a little too easy but it’s not bothered me so far. I’m mainly doing it because I like the coloured arms so might as well fit the wide ones.
just my 2p worth.
