Anyone know where or how I can get some touch up paint for uforce 1000 '22 model galaxy gray?  Thanks!

Bought the uforce 1000 about a month and half ago.  Decided to test it out.  Only can get 5900-6000 rpm's out of it then the gas just gives up.  Is there a safety feature or rev limiter on this thing shutting it down?  I don't think the work/normal mode has anything to do with it. Thanks for your help.
