Hi, Joly cat from OSE, KB45 1000KV from OSE, Sentilon HV100 esc from Unitedhobbies, 24 IB3600 cells from.... anywhere, x442 or x445 prob, this set up will take you to 50mph++++, but for what i know the Joly cat is not in stock and its $500 with hardwares, personally i think it too much, i beter go with the H&M M1 Cat and some FDM hardware for much cheaper.
