Hi guys , i have a turnigy trooper 4x4 brushless , ive put my vxl 3s esc in and ran the stock 2080kv motor with not one single issue , now ive just bought a 7.5t sensored orion vortex brushless motor and it runs 100% without the pinion on , as soon as its all bolted in and ready to go it seems as though there is a rev limiter like on a 1/1 scale and it all gets hot to the point the battery cables have melted , the pinion is 14t but im unsure what tooth the center diff is ? , would you say its an over gearing issue ?
Thankyou for your help in advance

ps its running on 2s
