Need Help to identify

[everythinghobbyshop]

Can someone please help me identify these items?
Was told it was bought around 2014 or 2015 and all parts come from the same rc.
Nothing has a name obviously, but the chassis has a small sticker that says "QC Passed"
The fuel bottle is set up to mix gas and oil.
I have been looking for info all over the internet and have come up with nothing.
Sorry for the bad pictures.
Any help would be appreciated.
Thanks
