yes the stock esc can handle any 27 turn. BUT AS I SAID DO NOT RUN A 19 TURRN 12,10,8, etc. it will burn up the esc. yes the truck does introduce you to r/c and how to work on a vehicle. but for racing the parts you can get in the stress area are stock and they just are not very good, also very tracks will have parts on hand for the raven. thus not very good unfortunately for racing, there are some parts though that losi parts will fit the truck.
