[mtsmat2008]

sup guys,after many engines and engine rebuilds i am thru with nitro and taking the plundge into brushless i am planning to do my first nitro to brushless on my lst2. i plan on running 5s lipo with stock gearing 24/63. i am just having trouble deciding what motor/esc combo to use. its either the hobby wing 4465sl (2000 kv 150a esc) and the mamba monster (2200 kv 120a esc)does any body suggest either one to power such a heavy truck
