Hi and hello to the forum as a newbie here!!! 
I have had my Arrma Kraton for 1 week now and have driven it 3 times. The 2nd and today (3rd) this front diff joining cup has come off again after re-assembling it last night. Not very impressed! Is there an upgrade or something I need to do to make sure this cup doesn't come off? I noticed that I had to line up the flat part of the diff gear (ar310498) that sticks through the housing/bearing with the grub screw tightening. If this is a weakness on this truggy and there is no fix I will have to send it back. Expected more for something that cost what it did. Any pointers will be appreciated!
I also noticed that the mount that holds down the top of the engine had a missing screw and on further inspection found the hole hadn't even been correctly been drilled! (top right screw location in pic) Should I take this back to the dealer I brought it from? (modelsport.co.uk)
I look forward to running this all the time, but haven't even managed to run the batteries out on this Kraton yet!
Many thanks
Jon
