racer 250 and devo 8

i contemplate buying a racer 250 eachine at banggood.
I posses a devo 8 with deviationtx installed (a nightly build) and i will use a walkera receiver on the racer.
My question is: is there a model file already existing for a devo 8? Can i find a tutorial dedicated to 250 racer?
anything to know for this type of drone?
Thanks
Christophe

Good question i am looking for the same . I have the eachine racer with a dsm2 rx and use my Devo 7e with of course deviation installed.
